Abstract
Macular amyloidosis (MA) is a skin condition with predominance in young women. We aimed to evaluate quality of life (QoL) and psychopathologies in these patients. In this cross-sectional study, patients with MA referring to the Imam Reza Hospital, Mashhad during 2018-2020, and their matched controls were included. Participants completed the 36-item short form survey (SF-36), the revised symptom checklist-90 (SCL-90-R), and the dermatology life quality index (DLQI). Overall, 40 women with a mean age of 36.80±10.19 years were studied. In the MA group, the SF-36 score was lower (P<0.001), and the SCL-90-R score was higher (P<0.001). The DLQI score was correlated with age (r=0.447; P=0.048) and pruritus severity (r=0.776; P<0.001), and was lower in patients with uncovered lesions (P=0.005). MA was associated with impaired QoL, which was determined by pruritus severity and lesion location; these patients can benefit from psychiatric interventions in this regard.

Abstract
The medical curriculum consists of basic pre-clinical and clinical parts. Basic sciences are required for diagnostic and clinical reasoning but students do not have a positive attitude toward basic sciences, mostly because of the lack of clinical relevancy. Basic sciences have many applications in the prevention, diagnosis, and treatment of a broad range of diseases but do not attract the attention of medical students. The aim of this study was to investigate the influence of clinical experts' opinions on the attitude of medical students toward basic sciences, particularly immunology. The opinion of six clinical specialists in different fields was recorded in a video clip, presenting the application of basic sciences and immunology in their routine practice. The attitude of second-year medical students toward the basic science courses was evaluated by a questionnaire containing four ranking questions and one short answer. The video clip was streamed and after that, students were answering the same questions. In total, 188 students including 129 s-year students (M/F ratio: 0.92) and 59 third-year students M/F ratio: 0.90) participated in the study. For all ranking questions, the mean score was significantly increased after watching the interviews' film streaming. Before watching the video clip, only 14.9% of students considered immunology as an important course but after that, the percentage significantly increased to 58.5% (P < 0.001). The results of this study showed that knowing clinical specialists' opinions about basic sciences significantly improved the attitude of students toward basic science courses, in particular immunology.

Abstract
Mycobacterium tuberculosis can spread through the entire body but rarely involves the eye. We report a patient with endophthalmitis in one eye and simultaneous retinal vasculitis in the fellow eye. Systemic work-up suggested infective endopericarditis. Polymerase chain reaction analyses of the vitreous and pericardial fluid were positive for M. tuberculosis. We initiated a four-drug antituberculous treatment regimen (isoniazid, ethambutol, pyrazinamide, and rifampin). After two weeks, we discontinued all the medications due to drug-induced hepatitis. We restarted isoniazid and rifampin, but hepatitis recurred. Finally, we chose isoniazid/ethambutol combination for 18 months, and also administered short-term systemic corticosteroid. His vision improved considerably with no recurrence of hepatitis or tuberculosis for 3 years after completion of treatment. Ocular tuberculosis can masquerade as other causes of intraocular inflammation, and a medical team consisting of an ophthalmologist and an infectious disease specialist might be needed for the diagnosis and management.

Abstract
The emergence of Escherichia coli sequence type 131 (ST131) as a multidrug-resistant and virulent pathogen represents a major challenge to public health globally. Recently, the O25b/ST131 E. coli producing CTX-M-15 with high virulence potential has been reported worldwide, but has received little attention in Iran. This study is the first in Iran to specifically determine the spread of the O25b/ST131 clone producing CTX-M-15 among E. coli isolates belonging to the B2 phylogenetic group. ST131 clone in phylogenetic group B2 was detected based on PCR detection of ST131-specific single-nucleotide polymorphisms in mdh and gyrB. O25b/ST131 E. coli clone was confirmed utilizing O25b/ST131 clone allele-specific PCR for the pabB gene. All group B2 E. coli isolates were characterized based on antibiotic susceptibility, extended-spectrum β-lactamase (ESBL) enzymes, and virulence traits. Our results demonstrated that 38 out of the 154 B2 group isolates (24.7%) were identified as belonging to the ST131 clone. Furthermore, of these, 28 isolates (73.6%) were detected as O25b/ST131 clone. Antibiotic resistance of ST131 E. coli isolates to ciprofloxacin, gentamicin, cefotaxime, and aztreonam was significantly higher than non-ST131 isolates. Almost all of the O25b/ST131 isolates with the ability for ESBL production were reported as CTX-M-15 producing (95.5%). Our results showed that the most prevalent virulence trait in ST131 clone was ompT (94.7%). This study is the first to report the prevalence of the CTX-M-15-producing O25b/ST131 E. coli in Iran. Our findings reinforce the surveillance of dissemination of ST131 E. coli clone as a major drug-resistant pathogen and an important new public health threat.

Abstract
Present study was designed to compare the potential effects of high serum levels of LDL and oxidised LDL (OxLDL) on spermatogenesis parameters in male Wistar rats. Animals were allocated into three groups and were fed for 14 weeks with normal, cholesterol-rich and oxidised cholesterol-rich diets. Blood lipid profile, sex hormones level, as well as sex organs weight were evaluated. The sex organs weight in oxidised cholesterol-fed group was significantly reduced (P < 0.05). Spermatozoa count in the group with high serum concentration of OxLDL (64 ± 4.2 × 10(6) ) was markedly lower (P < 0.01) than that of normal rats (87 ± 4.1 × 10(6) ) and rats with high serum level of LDL (90 ± 6.3 × 10(6) ). Similarly, the percentage of viable spermatozoa was significantly (P < 0.001) decreased from 78% to 52% by high level of OxLDL in serum. While, nonoxidised LDL did not have suppressive effects on spermatogenesis and organs weight. Consistent with these effects, the serum concentration of sex hormones including FSH (P < 0.001), LH (P < 0.001) and testosterone (P < 0.01) was significantly decreased only in rats with high level of OxLDL but not in rats with high level of nonoxidised LDL. In conclusion, high OxLDL level showed higher destructive effect on reproductive system compared to the high LDL level.

Abstract
BACKGROUND It is estimated that one-third of infertility cases are due to male factors. Hyper-cholesterolemia is a social problem in many developed countries and contributed with a heterogeneous group of disorders characterized by an excess of cholesterol and its derivatives in the blood stream. PURPOSE The objective of the present study was to investigate the protective effects of coenzyme Q10 and L-Carnitine supplementation on semen parameters, sperm function and reproductive hormone profiles in male Wistar rats with high LDL and Oxidized LDL (OxLDL) blood levels. METHODS Animals were fed with cholesterol and oxidized cholesterol-rich diets for 14 weeks to elevate the LDL and OxLDL blood level, respectively. Pretreatment with coenzyme Q10 (10 mg/kg/day, oral) and L-Carnitine (350 mg/kg/day, oral) were conducted for 5 consecutive weeks. Sex hormones levels, malondialdehyde and total antioxidant concentrations, as well as testis, epididymis and seminal vesicle weight were also analyzed. RESULTS Following high LDL and OxLDL blood levels, decrease in the sperms count and viability, weights of testis, epididymis and seminal vesicle as well as concentration of testosterone and LH hormone were observed. On the other hand, in contrast to reduction of total antioxidant level, malondialdehyde concentration, both in serum and testis, was increased. However, pretreatment with L-carnitine and coenzyme Q10 increased serum sex hormones level and improved semen parameters significantly. CONCLUSION Overall, pretreatment with coenzyme Q10 and L-Carnitine attenuated the destructive effects of high LDL and oxidized LDL levels on spermatogenesis parameters in male rats.

Abstract
Nowadays, cardiovascular diseases and male infertility are two big health problems in industrial countries.The aim of the present study was to investigate the protective role of coenzyme Q10 and L-Carnitine pretreatment in the impaired spermatogenesis caused by isoproterenol (ISO) in male rats.Thirty-two male Wistar rats were allocated in 4 groups. ISO was injected for 2 consecutive days (100 mg/kg) in ISO treated groups. Before ISO administration, pretreatment with Coenzyme Q10 (10 mg/kg/day) and L-Carnitine (350 mg/kg/day) were conducted for 20 consecutive days. Sex hormones level, malondialdehyde (MDA) and total antioxidant concentration as well as testis, epididymis and seminal vesicle weight were investigated.Increase in the concentration of MDA and decrease in total antioxidant level was observed following ISO administration. Accordingly, the sperm viability as well as testis, epididymis and seminal vesicle weights were decreased. In the case of sex hormones, the testosterone and LH levels were decreased and the concentration of FSH was increased. Pretreatment with L-carnitine and Coenzyme Q10 significantly decreased the MDA level and increased total antioxidant, LH and testosterone levels. Pretreatment with L-carnitine and Coenzyme Q10 also improved semen parameters and organs weight which were impaired by ISO administration.L-carnitine and Coenzyme Q10 pretreatment could protect spermatogenesis in male rats with ISO administration.

Abstract
BACKGROUND Exposure to house dust mites (HDMs) is a major risk factor for the development of allergic symptoms. HDMs are worldwide in distribution. Assessing these allergens in each area is a critical step in evaluating the risk of sensitisation and controlling allergic symptoms. The aim of the present study was to evaluate the level of major HDMs, Der p 1 and Der f 1, in various parts of Iran. METHODS In 2009, 257 dust samples were obtained from living rooms' carpets in seven cities throughout Iran with different geoclimatic conditions. The level of Der p 1 and Der f 1 was measured by commercial ELISA. RESULTS Detectable level of Der p 1 and Der f 1 levels were only found in Gorgan and Sari, two cities near the Caspian Sea with moderate temperatures and high relative humidity. In both of these cities, Der f 1 was more frequent than Der p 1 (100% vs. 85%) and was found to be at a higher level than Der p 1 (geometric mean 3128 vs. 439ng/g dust, P<0.001). CONCLUSION The results of this study confirm that house dust mites in Iran are restricted to the Caspian Sea coastal areas, and in other parts, due to seasonal variations of temperature and humidity mites are not able to grow well and therefore are not an important risk factor for sensitisation and respiratory allergies.

Abstract
Mutations within the coding region of hepatitis B surface antigen (HBsAg) have been found naturally in chronic carriers. To characterize the mutations of HBsAg from Iranian chronic carriers who were vaccine and/or medication naive. The surface genes from 360 patients were amplified and directly sequenced. The distribution of amino acid substitutions was classified according to different immune epitopes of the surface protein. All isolates belonged to genotype D. 222 (61.6%) of 360 patients contained at least one amino acid substitution. 404 (74.5%) of 542 amino acid changes occurred in different immune epitopes of HBsAg, of which 112 (27.7%) in 32 residues of B-cell epitopes (62 in the 'a' determinant); 111 (27.4%) in 32 residues of T helper; and 197 (48.7%) in 32 residues inside cytotoxic T lymphocyte (CTL) epitopes. One Th (186-197) and two CTL (28-51 and 206-215) epitopes were found to be hotspot motifs for the occurrence of 213 (52.7%) substitutions. 20 stop codons were identified in different epitopes. There was a significant association between amino acid substitutions and anti-HBe seropositivity; however, the correlation between such changes with viral load and ALT levels was not significant. In chronic hepatitis B virus(HBV) carriers, positive selection in particular outside the 'a' determinant appeared to exert influence on the surface proteins. These changes could be immune escape mutations naturally occurring due to the host immune surveillance especially at the T-cell level.

Abstract
This study was designed to determine the correlation of hepatitis B virus surface Ag (HBsAg) variations with the clinical/serological pictures among chronic HBsAg positive patients. The surface gene (S-gene) was amplified and directly sequenced in twenty-five patients. Eight samples (group I) contained at least one mutation at the amino acid level. Five showed alanine aminotransferase (ALT) levels above the normal range of which only one sample was anti-HBe positive. Group II (17 samples) did not contain any mutation, 4 were anti-HBe positive and 9 had increased ALT levels. In both groups, from a total of 18 mutations, 5 (27.5%) and 13 (72.5%) occurred in anti-HBe and HBeAg positive groups respectively. The small number of amino acid mutations might belong to either the initial phase of chronicity in our patients; or that even in anti-HBe positive phase in Iranian genotype D-infected patients, a somehow tolerant pattern due to the host genetic factors may be responsible.

Abstract
BACKGROUND AND AIMS Currently, vaccination is the most effective protective tool against hepatitis B virus infection. Some studies have shown that positive results for a hepatitis B virus surface antigen (HBsAg) test may be seen after vaccination. MATERIALS AND METHODS In this clinical trial study, 62 healthy adult volunteers were randomly assigned to receive either the Engerix-B or the Hepavax-Gene hepatitis B recombinant vaccine. Blood samples were drawn 1, 3, and 5 days after vaccination and were tested for HBsAg using two different ELISA kits (Behring and Mega). RESULTS HBsAg was positive in 5, 3, and 2 participants of the Engerix-B group in the 1st, 3rd, and 5th days after vaccination, respectively, using the Behring ELISA kit the test was positive in only one subject in the Hepavax-Gene group, on the 5th day after vaccination. No positive result was seen in any groups when the Mega ELISA kit was used to test the specimens. CONCLUSIONS Our results showed transient HBsAg antigenemia after vaccination against hepatitis B. This condition depends on the type of vaccine and the HBsAg diagnostic test.

Abstract
Severe hypertension occurred as a postoperative complication after correction of a club-foot deformity in four children (seven feet) who were between the ages of two and three years and had no history of hypertension. The hypertension subsided slowly after administration of antihypertensive medications or more rapidly after release of the correction that had been obtained operatively.
