COVID-19 preventive behaviors and influencing factors in the Iranian population; a web-based survey

Background: COVID19 is a respiratory disease caused by a novel coronavirus. As there has been no definitive treatment for the disease so far, the only way to control the spread is to break the chain of infection. Our study aimed to analyze the preventive behaviors and influencing factors in the Iranian population. Methods: This cross-sectional study was a web-based survey in the Iranian population. We performed the study during the first peak of COVID-19 outbreak (from March 25th, 2020 to April 5th). We used demographic and Preventive behaviors questionnaires to collect the data. This web-based survey was publicized on the internet through the common platforms used by the Iranian population. This survey was released on the website “Porsline.com”. A total of 2097 acceptable questionnaires were filled. All data were analyzed, using Statistical Package for Social Sciences (SPSS) version 19. Results: 61.9% of the participants checked the hand-washing question as “Always”. 55.7 and 58.2% checked the wearing masks and gloves as “Always”, respectively. We found a significant relationship between gender and hand washing behavior (P = 0.006) and the use of masks and gloves (P < 0.001). Results showed that wearing gloves had a significant relation with the education status (P = 0.029) and economic status (P = 0.011). Wearing masks had a significant relation with economic status (P = 0.032). Overall women had better preventive behaviors. Conclusions: Preventive behaviors have a significant relation with some socio-demographic characteristics. According to the 3 main preventive behaviors of hand-washing, wearing masks and gloves 50% of the population has not taken these behaviors seriously

Comparison of Clinical Findings of Acute Appendicitis and Mesenteric Lymphadenitis in Children with Acute Abdominal Pain

Background and Objective: Mesenteric lymphadenitis is an inflammatory process that has similar clinical symptoms to appendicitis among diseases associated with acute abdominal pain. Therefore, the aim of this study was to compare clinical and paraclinical findings in children with appendicitis and mesenteric lymphadenitis. Methods: This cross-sectional study was conducted on 214 children who were admitted to Amirkola Children's Hospital in 2011-2021 with the diagnosis of appendicitis (112 people) or mesenteric lymphadenitis (102 people). Appendicitis and mesenteric lymphadenitis were diagnosed based on pathology and ultrasound, clinical symptoms, laboratory parameters and ultrasound of children were compared in two groups. Findings: Out of 214 children, 112 (52.15%) were girls and the mean age of the children was 7.53±3.19 years. Children with appendicitis compared to children with mesenteric lymphadenitis were more likely to have tenderness (42.2% vs 85.7%, p<0.001), rebound tenderness (40.2% vs 4.9%, p<0.001), vomiting (79.5% vs 61.8%, p=0.004) and pain shift (11.8% vs 25%, p<0.013). Also, WBC (9774.51±3971.35 vs 15358.04±4635.20, p<0.001), neutrophil (63.42±17.05 vs 77.02 ± 10.51, p<0.001), ESR (19.73±18.56 vs 38.57±27.29, p<0.001) and CRP (18.00±27.98 vs 52.77±40.30, p<0.001) were significantly higher in children with appendicitis. Ultrasound sensitivity (0.73-0.88) was 80.4% in diagnosing appendicitis and rejected mesenteric lymphadenitis with 100% probability. Conclusion: The results of the study showed that some clinical symptoms with leukocytosis, neutrophilia and high CRP can help differentiate appendicitis from mesenteric lymphadenitis. But ultrasound can have a more definitive result in this regard

HIV and HPV infections and ocular surface squamous neoplasia: systematic review and meta-analysis.

BACKGROUND: The frequency of ocular surface squamous neoplasias (OSSNs) has been increasing in populations with a high prevalence of infection with human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) and infection with human papillomavirus (HPV). We aimed to quantify the association between HIV/AIDS and HPV infection and OSSN, through systematic review and meta-analysis. METHODS: The articles providing data on the association between HIV/AIDS and/or HPV infection and OSSN were identified in MEDLINE, SCOPUS and EMBASE searched up to May 2013, and through backward citation tracking. The DerSimonian and Laird method was used to compute summary relative risk (RR) estimates and 95% confidence intervals (95% CI). Heterogeneity was quantified with the I(2) statistic. RESULTS: HIV/AIDS was strongly associated with an increased risk of OSSN (summary RR=8.06, 95% CI: 5.29-12.30, I(2)=56.0%, 12 studies). The summary RR estimate for the infection with mucosal HPV subtypes was 3.13 (95% CI: 1.72-5.71, I(2)=45.6%, 16 studies). Four studies addressed the association between both cutaneous and mucosal HPV subtypes and OSSN; the summary RR estimates were 3.52 (95% CI: 1.23-10.08, I(2)=21.8%) and 1.08 (95% CI: 0.57-2.05, I(2)=0.0%), respectively. CONCLUSION: Human immunodeficiency virus infection increases the risk of OSSN by nearly eight-fold. Regarding HPV infection, only the cutaneous subtypes seem to be a risk factor

A clinicopathologic study of orbital and ocular adnexal lymphoproliferative lesions with immunohistochemical staining of indeterminate cases

The histopathologic diagnosis of orbital and ocular adnexal lymphoproliferative lesions is difficult, resulting controversy in classification, determining benignity or malignancy of them and treatment modality selection. We designed the following study to evaluate clinical, histopathologic and if necessary immunochemical features of them in decreasing indeterminate cases. The study includes 51 subjects of biopsy-proven orbital lymphoid lesions and inflammatory pseudotumors from pathologic practices of Farabi and Imain Khomeini Hospitals, from April 1994 to March 2000. We reviewed H&amp;E stained slides. Then we examined clonality of indeterminate cases with evaluation of clonal immunoglobulin light chains (&amp;#312; or &amp;#955;) expression to find neoplastic cells. CD markers were used for excluding other closed morphologic differential diagnosis. In conclusion we determined 40 cases of lymphoproliferative lesions, divided to the following there groups: malignant lymphoma with sixty-five percent frequency were the most common type of them, reactive lymphoid hyperplasia with twenty percent was the second one and atypical lymphoid hyperplasia with fifteen percent was the third one. The most common site of involvement was orbit (57.5%). Males were affected slightly higher than females. Median age at diagnosis was 62 years. The most common type of lymphoma group was low-grade small lymphocytic lymphoma. It is necessary to note that 11 out of total 51 subjects were excluded under other pathologic diagnosis. On the other hand 4 cases of already diagnosed pseudo-tumors were reclassified into three lymphoid lesion categories above

ENUCLEATION IN A PATIENT WITH NEUROFIBROMATOSIS TYPE 1 WITH BUPHTHALMOS AND OCULAR DEFORMITY

To report a case of buphthalmos with neurofibromatosis (NF-1) who suffered with blindness suffered enucleation. Physical examination &amp;amp; histopathology were performed. Physical examination revealed Buphthalmos &amp;amp; vascularized cornea with lower lid ectropion and orbital deformity. Histopathologic findings shows plexiform neurofibroma in orbital tissue with scleral wall involvement. And hamartomatous proliferation in choroid &amp;amp; cilliary bodies with melanocytic elements. Few NF-1 cases with buphthalmos have been reported. But cases with complicationg buphthalmos (retinal Detachment &amp;amp; optic nerve Atrophy) suffering enucleation are very rare

Histopathological Study Of Eyelid Tumor Tehran Farabi Hospital (1988-98)

There are few studies of eyelid&apos;s neoplasm in Asia which in comparison of references are some differences.&quot;nMaterials and Methods: For this reason the retrospective study in 1103 patients which are referred to Farabi Hospital in 10 years period of 1988-1998 was performed. Epidemiological and histopathologic details were sough.&quot;nResults: 44 percent of the neoplasm were benign and 56 percent were malignant. The most prevalent benign neoplasm of eyelid respectively were Nevus (37.7 percent) hamartoma (19.6 percent) and papilloma (15.9 percent) and malignant neoplasm of eyelid respectively were basal cell carcinoma (78.7 percent), squamous cell carcinoma (11.8 percent ) and melanoma (2.4 percent ). The mean age in benign neoplasm was 36 years and in malignant ones 57 years, In benign tumors the most prevalent anatomical site respectively were upper eyelid, lower eyelid and inner canthus. But in malignant tumors it was occurred most frequently in upper eyelid in comparison to lower eyelid in addition occurrence of malignant tumors was prevalent in left but in benign neoplasm right and left eyelid were involved equally.&quot;n&quot;n&quot;n&quot;n&amp;nbsp

PRIMARY CHOROIDAL MALIGNANT LYMPHOMA:REPORT OF A CASE AND REVIEW OF LITERATURE

Non-Hodgkin lymphoma (NHL) is one of the masquerade syndromes of malignant melanoma that can occur with two main patterns of presentations in the eye: metastatic involvement of uveal tract, and primary involvement of retina. We report ophthalmic, imaging and histopathological findings in the first case diagnosed as primary choroidal NHL without central nervous system or systemic involvement. A 37-year-old woman presented with the complaint of severe visual loss in her right eye. Significant ocular finding included light perception of vision (LP), 2+ APD, 2+ cells in vitreous and intraocular pressure of 46 mmHg. Fundoscopic examination revealed exudative retinal detachment. Ocular echography showed choroidal thickening in addition to retinal detachment. MRI showed semilunar shape lesion in the posterior right globe suggesting choroidal melanoma. Systemic work-up could not reveal any underlying cause. The patient underwent enucleation with clinical suggestion of choroidal melanoma. Result of histological examination showed NHL (diffuse large Bcell type) of choroid. Immunohistochemical staining showed negative staining for HMB-45 and CD3, positive staining for LCA, and CD20. Multiple periodic lumbar puncture, bone marrow biopsies and MRI were unremarkable. No recurrence of tumor in systemic work-up was noted during the 36-months follow-up. Primary choroidal NHL is one of the causes of generalized thickening of choroid and should be considered in differential diagnosis of malignant melanoma. It is recommended to perform fine needle biopsy before performing surgery in any patient who has had an atypical malignant melanoma. This is, so far as we know, the first case diagnosed as primary choroidal NHL

PERIBULBAR COMPLEX CHORISTOMA IN ASSOCIATION WITH IPSILATERAL NASAL HYPOPLASIA AND NASOLACRIMAL DUCT OBSTRUCTION

Developmental midline perinasal masses in children are rare lesions specifically in association with choristomas. We encountered a 3-year-old boy with epiphora, a striking mass on the nasal bridge and ipsilateral nasal hypoplasia. CT scan imaging showed multiple calcified areas within the tumor in addition to linear defect in frontal bone, hypoplastic left ethmoidal sinus and left nasal cavity, and absence of left nasal concha. The patient had no history of seizure, no neurologic deficit, and ocular developmental exams were normal. After performing excisional biopsy of the tumor, histopathologic analysis revealed complex choristoma composed of cartilage and bone. The most appropriate name for this malformation, which we have not found described in the literature, seems to be, nasal hypoplasia with complex choristoma and nasolacrimal duct obstruction
