RESUMO
BACKGROUND: Aspergillus endocarditis (AE) is a rare fatal infection. The infection is often reported in patients with prosthetic heart valves, immunosuppressed, broad-spectrum antimicrobial use regimens, and drug abusers. METHODS: Herein, we report a rare case of native mitral valve AE in a 63-year-old man, with a probable COVID-19-associated invasive pulmonary aspergillosis nine months ago treated with antifungals. RESULTS: In the last admission, the lethargy, neurological deficit, and septic-embolic brain abscess in brain MRI led to suspicion of infective endocarditis. Transesophageal two-dimensional echocardiography and color Doppler flow velocity mapping showed a large highly mobile mass destroying leaflet and severe mitral regurgitation. The Surgical valve replacement is performed. The surgical valve replacement is performed. Direct microscopic examination and culture of the explanted and vegetative mass revealed Aspergillus section Fumiagati confirmed by molecular method. Despite the administration of voriconazole and transient improvement the patient expired. CONCLUSION: As AE is a late consequence of COVID-19-associated invasive pulmonary aspergillosis, therefore, long-term follow-up of invasive aspergillosis, and prompt diagnosis of surgical and systemic antifungal therapy treatment, are warranted to provide robust management.

BACKGROUND: A protective effect of vitamin D against COVID-19 infection is under investigation. We aimed to analyze the effect of vitamin D sufficiency on the clinical outcomes of patients infected with COVID-19. METHODS: In this cross-sectional study we analyzed the vitamin D levels of COVID-19 patients who were admitted to Razi Hospital (an infectious disease referral center in Mazandaran province in northern Iran) from February to March 2020. Overall, a cutoff point of 30 ng/mL was used for the definition of vitamin D sufficiency. RESULTS: One hundred fifty-three patients were analyzed in this study who had laboratory documentation of a 25(OH) D level at the time of hospitalization. The vitamin D levels of the patients were 27.19 ± 20.17 ng/mL. In total, 62.7% (n = 96) of the patients had a 25(OH) D level of less than 30 ng/mL and 37.25% (n = 57) had a 25(OH) D level of more than 30 ng/mL. In total, 49% (n = 75) of the patients suffered from at least one underlying disease. The univariate and multivariable regression showed that vitamin D sufficiency was not associated with a statistically significant lower risk of adverse clinical outcomes of COVID-19 such as duration of hospitalization and severity of infection (P > 0.05). CONCLUSIONS: Sufficient vitamin D levels were not found to be protective against adverse clinical outcomes in patients infected with COVID-19. Chronic disorders in COVID-19 patients were found to have greater relevance than vitamin D levels in determining the adverse outcomes of the infection. Further studies are needed to determine the role of vitamin D level in predicting the outcomes of COVID-19 infection.

We report an unusual case of co-infection of invasive pulmonary aspergillosis (IPA) and fusarial skin infection in a patient with classic pyoderma gangrenosum with unknown causes, which were previously controlled with oral prednisolone, cyclosporine. The diagnosis was made on direct microscopy and culture of endobronchial washing, bronchoalveolar lavage and skin lesion biopsy. The treatment failed, and the patient expired 12 days following hospitalization. This report highlights the rarity of coexistence of IPA and a chronic fusarial skin infection and thereby reinforcing the physician's attention toward the possibility of invasive fungal infection in the immunosuppressed patients.
RESUMO
BACKGROUND: Icterohemorrhagic form of leptospirosis has a high mortality rate. In this study, the clinical manifestations, epidemiologic and laboratory findings and outcome of Weil's disease were investigated. METHODS: A descriptive cross- sectional study was conducted on 66 consecutive patients with icterohemorrhagic leptospirosis who were admitted to Razi Hospital (The Therapeutic Center of Infectious Diseases in the North of Iran) in 2013. The inclusion criteria were as follows: All patients who had clinical and epidemiological data suggestive of leptospirosis and displayed icterohemorrhagic form at the time of admission or during hospitalization. All patients were visited on admission, one, two and six weeks later. Demographic data, clinical, laboratory features and complications were evaluated, and statistical analysis was performed using SPSS version 13.0. RESULTS: Among 66 patients, 89.4% (n = 59) were male, 60% (n = 40) were farmers and 9.1% (n= 6) had a history of swimming in rivers. The most common complaints were fever and jaundice, respectively. The most common clinical symptoms were fever (90.9%), myalgia (75.8%), chills (70.8%) and headache (65.1%). Hyponatremia and hypernatremia were seen in 7.6% and 72.8% of the participants, respectively. Also, hypokalemia was observed in two patients (3%). Approximately, half of the cases had leukocytosis and 90% had thrombocytopenia. Rise of AST, ALT, ALP and bilirubin were seen in 95.2%, 93.6%, 76.2% and 100% of the patients, respectively. Of the patients, 42.4% experienced complications of icterohemorrhagic leptospirosis including acute renal failure (30.3%) pneumonia (25.8%), pancreatitis (4.5%), subarachnoid hemorrhage (1.5%) and gastrointestinal bleeding (1.5%). Three cases (4.5%) died, 42 cases (63.7%) were discharged with residual effects and 52 patients (78.8%) had positive serology. CONCLUSION: The most significant biochemical abnormalities were thrombocytopenia, hyperbilirubinemia, hyponatremia and hypernatremia and azotemia and the latter remained stable in 2% of the patients at least until the end of the 6-week period.
RESUMO
Background: Hepatitis B (HBV) and hepatitis C viruses (HCV) are significant causes of liver disease worldwide. Liver fibrosis (LF) is a complication of chronic liver damage caused by HBV and HCV due to our limited knowledge comparing the diagnostic performance of platelet to aspartate aminotransferase ratio index (APRI) and fibrosis-4 (FIB-4) index with fibroscan. Methods: This study evaluated liver damage in HBV and HCV using APRI, FIB-4, and fibroscan indices. This retrospective cohort descriptive-analytical study was conducted on patients with HBV and HCV. This study uses laboratory results and imaging to investigate liver damage in chronic HBV and HCV patients. APRI and FIB-4 were computed based on laboratory results. Results: A total of 185 patients (82 hepatitis B and 103 hepatitis C) were included in the study. Thirteen patients had liver cirrhosis. There was no statistically significant difference between the fibroscan results in the two groups (P=0.99). The HBV group's mean APRI and FIB-4 were lower than HCV, but no significant difference was observed (P>0.05). Our results in HBV and HCV patients showed that APRI and FIB-4 accomplished well anticipating cirrhosis with an area under the receiver operating characteristic curve (AUC) of 0.771-0.845 and 0.871-0.910, respectively. Conclusion: Fibroscan is a powerful tool superior to APRI and FIB-4 in predicting LF and cirrhosis. Nevertheless, APRI and FIB-4 are inexpensive and non-invasive indicators with acceptable efficacy in predicting advanced fibrosis or cirrhosis. However, these two measures are not reliable in low-grade fibrosis.
RESUMO
BACKGROUND: Contradictory opinions exist regarding the use of angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) in patients with hypertension, which is the most common comorbidity associated with COVID-19. Herein, the effects of ACEIs and ARBs on outcomes of COVID-19 patients were evaluated. METHODS: In this cross-sectional study, the outcomes of COVID-19 patients were compared between patients who received pretreatment ACEIs or ARBs and those who did not. RESULTS: The incidence of moderate and severe forms of COVID-19 was significantly higher in patients taking ACEI/ARB drugs (P-value = 0.012). Also, patients taking ACEI/ARB drugs (P-value = 0.034), patients with hypertension (P-value = 0.011), and patients with dyslipidemia (P-value = 0.011) experienced more severe forms of COVID-19. There was an association between increased length of hospital stay and dyslipidemia (P-value = 0.033) and the use of ACEI/ARB drugs (P-value = 0.041), while no correlation was found between other parameters in univariate linear regression analysis as well as multivariate linear regression. There was an association between increased mortality of patients with increasing age (P-value < 0.001), BMI greater than 30 kg/m2 (P-value = 0.02), asthma (P-value = 0.003), and dyslipidemia (P-value = 0.045). CONCLUSIONS: ACEI/ARB drugs put COVID-19 patients at high risk for moderate to severe forms of COVID-19 and higher length of hospital stay. Although, it is notable that these drugs did not significantly affect specific adverse outcomes of COVID-19, such as the need for admission to the intensive care unit (ICU), length of ICU stay, ventilation, and mortality.

Introduction: The occurrence of oral candidiasis (OC) is expected in patients with COVID-19, especially those with moderate to severe forms of infection who are hospitalized and may be on long-term use of broad-spectrum antibiotics or prolonged corticosteroid therapy. We aimed to characterize clinical conditions, the prevalence profile of Candida species, and outcomes of COVID-19 patients with OC. Methods: In this observational study, oral samples were obtained from COVID-19 patients suspected of OC admitted to Razi teaching hospital. Patients with OC were monitored daily until discharge from the hospital. Species identification was performed by a two-step multiplex assay named YEAST PLEX, which identifies 17 clinically important uncommon to common yeast strains. Results: Among the 4133 patients admitted with COVID-19, 120 (2.90%) suffered from OC. The onset of signs and symptoms of OC in patients was, on average (2.92 ± 3.596 days) with a range (of 1-29 days). The most common OC presentation was white or yellow macules on the buccal surface or the tongue. In (39.16%) of patients suffering from OC multiple Candida strains (with two or more Candida spp.) were identified. The most common Candida species were C. albicans (60.57%), followed by C. glabrata (17.14%), C. tropicalis (11.42%), C. kefyr (10.83%) and C. krusei (3.42%). Notably, OC caused by multiple Candida strains was more predominant in patients under corticosteroid therapy (P <0.0001), broad-spectrum antibiotics therapy (P = 0.028), and those who used nasal corticosteroid spray (P <0.0001). The majority of patients who recovered from OC at the time of discharge were patients with OC by single Candida species (P = 0.049). Discussion: Use of corticosteroids and antimicrobial therapy in COVID-19 patients increases risk of OC by multiple Candida strains.

Background: Ivermectin which was widely considered as a potential treatment for COVID-19, showed uncertain clinical benefit in many clinical trials. Performing large-scale clinical trials to evaluate the effectiveness of this drug in the midst of the pandemic, while difficult, has been urgently needed. Methods: We performed two large multicenter randomized, double-blind, placebo-controlled clinical trials evaluating the effectiveness of ivermectin in treating inpatients and outpatients with COVID-19 infection. The intervention group received ivermectin, 0.4mg/kg of body weight per day for 3 days. In the control group, placebo tablets were used for 3 days. Results: Data for 609 inpatients and 549 outpatients were analyzed. In hospitalized patients, complete recovery was significantly higher in the ivermectin group (37%) compared to placebo group (28%; RR, 1.32 [95% CI, 1.04-1.66]; p-value = 0.02). On the other hand, the length of hospital stay was significantly longer in the ivermectin group with a mean of 7.98 ± 4.4 days compared to the placebo receiving group with a mean of 7.16 ± 3.2 days (RR, 0.80 [95% CI, 0.15-1.45]; p-value = 0.02). In outpatients, the mean duration of fever was significantly shorter (2.02 ± 0.11 days) in the ivermectin group versus (2.41 ± 0.13 days) placebo group with p value = 0.020. On the day seventh of treatment, fever (p-value = 0.040), cough (p-value = 0.019), and weakness (p-value = 0.002) were significantly higher in the placebo group compared to the ivermectin group. Among all outpatients, 7% in ivermectin group and 5% in placebo group needed to be hospitalized (RR, 1.36 [95% CI, 0.65-2.84]; p-value = 0.41). Also, the result of RT-PCR on day five after treatment was negative for 26% of patients in the ivermectin group versus 32% in the placebo group (RR, 0.81 [95% CI, 0.60-1.09]; p-value = 0.16). Conclusion: Our data showed, ivermectin, compared with placebo, did not have a significant potential effect on clinical improvement, reduced admission in ICU, need for invasive ventilation, and death in hospitalized patients; likewise, no evidence was found to support the prescription of ivermectin on recovery, reduced hospitalization and increased negative RT-PCR assay for SARS-CoV-2 5 days after treatment in outpatients. Our findings do not support the use of ivermectin to treat mild to severe forms of COVID-19. Clinical Trial Registration: www.irct.ir IRCT20111224008507N5 and IRCT20111224008507N4.
RESUMO
Statins can help COVID-19 patients' treatment because of their involvement in angiotensin-converting enzyme-2. The main objective of this study is to evaluate the impact of statins on COVID-19 severity for people who have been taking statins before COVID-19 infection. The examined research patients include people that had taken three types of statins consisting of Atorvastatin, Simvastatin, and Rosuvastatin. The case study includes 561 patients admitted to the Razi Hospital in Ghaemshahr, Iran, during February and March 2020. The illness severity was encoded based on the respiratory rate, oxygen saturation, systolic pressure, and diastolic pressure in five categories: mild, medium, severe, critical, and death. Since 69.23% of participants were in mild severity condition, the results showed the positive effect of Simvastatin on COVID-19 severity for people that take Simvastatin before being infected by the COVID-19 virus. Also, systolic pressure for this case study is 137.31, which is higher than that of the total patients. Another result of this study is that Simvastatin takers have an average of 95.77 mmHg O2Sat; however, the O2Sat is 92.42, which is medium severity for evaluating the entire case study. In the rest of this paper, we used machine learning approaches to diagnose COVID-19 patients' severity based on clinical features. Results indicated that the decision tree method could predict patients' illness severity with 87.9% accuracy. Other methods, including the K-nearest neighbors (KNN) algorithm, support vector machine (SVM), Naïve Bayes classifier, and discriminant analysis, showed accuracy levels of 80%, 68.8%, 61.1%, and 85.1%, respectively.

BACKGROUND AND PURPOSE: Rhinocerebral mucormycosis is a rare fatal fungal infection which is on a growing trend, particularly among immunocompromised patients. Immunosuppressive drugs, including corticosteroids and antimetabolites, increase the risk of this infection. Herein, we reported the case of fulminant rhinocerebral mucormycosis in a patient with ulcerative colitis receiving azathioprine and corticosteroid. CASE REPORT: A 58-year-old woman was admitted to the hospital in a state of coma with an extensive necrosis in her nose. She was afflicted with intestinal bleeding after 1 month of fasting and was treated with azathioprine and a high dose of prednisolone for ulcerative colitis 2 months prior to hospital admission. The direct microscopic examination of the necrotic tissues of the paranasal sinuses showed several non-septate hyphae consistent with Mucorales. Culture media yielded Rhizopus species, which was identified as Rhizopus oryzae by internal transcribed spacer polymerase chain reaction sequencing. Despite the implementation of surgical and pharmaceutical (liposomal amphotericin B) treatments, the patient expired after 2 weeks of admission. CONCLUSION: The gastroenterologists should be aware of the adverse effect of immunosuppressive drugs they prescribe for the treatment of inflammatory bowel disease.
RESUMO
Strongyloides stercoralis is a soil-transmitted helminth (STH) widespread in various part of the world. A 78-yr-old peasant diabetic female from Mazandaran Province northern Iran, was admitted to Infection Department of the Razi Hospital in city of Qaemshahr, north of Iran complaining about abdominal skin rash, pruritus, itching, anorexia, nausea, vomiting, dysuria and cough. This patient had cutaneous migration effects of S. stercoralis larvae in her abdominal skin (larva currents and urticaria). Lung CT without contrast demonstrate s bilateral diffuse ground glass opacity draws attention. Upper gastrointestinal endoscopy revealed gastro esophageal reflux with antral gastritis. Duodenal endoscopy showed unusual mucosa and a biopsy from it sent to the pathology laboratory. Histopathology of duodenal bulb and duodenum biopsy showed mild villous atrophy and S. stercoralis infection. The patient was treated with albendazole and clinical sings improved completely after treatment. Strongyloidiasis should be carefully considered by clinicians who practice in endemic areas. Clinicians must keep a high level of skepticism for patients from endemic area.
RESUMO
BACKGROUND: Patients who undergo cardiac surgery appear to be at increased risk for the development of Nosocomial infections (NIs). The development of antibiotic-resistant infections has been associated with significantly greater hospital mortality rates compared to similar infections caused by antibiotic-sensitive pathogens. OBJECTIVES: The purpose of this study is survey of Nis and antibiotic resistance patterns of causative bacteria among patients who underwent open heart surgery in the north of Iran during a 2-year period between September 2012 and September 2014. METHODS: In this cross-sectional study we evaluated 187 patients that underwent open heart surgery with NIs. Demographic feature, clinical characteristics and risk factors of each infection were recorded. The antibiotic susceptibility test was performed using the Minimum inhibitory concentration (MIC) method according to the standard protocol of Clinical & Laboratory Standards Institute (CLSI). Detection of Extended-spectrum beta-lactamase (ESBL) producing bacteria was performed by the double-disk synergy (DDS) test; also Methicillin-resistant Staphylococcus (MRSA) strains were identified by MRSA Screen Agar. The collected data were analyzed using the SPSS software (ver. 16) and, descriptive statistics were used. RESULTS: Out Of total of 2253 hospitalized patients who underwent open heart surgery, 187(5.05%) patients had NIs. 51.9% of the patients were female. The rates of surgical site infection (SSI), respiratory tract infection, endocarditis, Urinary tract infection (UTI), blood Infection and mediastinitis were 27.80, 25.66%, 17.64, 17.11% 8.55% and 3.20% respectively. E.coli and S.aureus were the most causative agents of NIs. The rate of ESBL-producing bacteria was 14.28- 71.42% among enterobacteriaceae and the rate of MRSA was 54.2% among S.aureus strains. All isolated Acinetobacter.spp were Multi-drug resistance (MDR). CONCLUSIONS: We showed that the rate of NIs among these high-risk patients was in the average level. But the emergence of MRSA and ESBL bacteria is increasing in our region.

BACKGROUND: Brucellosis can involve almost any organ system and may present with a broad spectrum of clinical presentations. In this study, we present a case of deep vein thrombosis due to human brucellosis. CASE PRESENTATION: A 15- year old boy presented with acute pain and swelling in his left thigh in June 2011, when he complained of fever, chills and lower extremity pain in which he could barely walk. In family history, his older brother had brucellosis 3 weeks ago and appropriate medication was given. The tubal standard agglutination test (wright test) and 2ME test were positive (in a titer of 1/1280 and 1/640, respectively). Peripheral venous doppler ultrasound of left lower extremity showed that common iliac, femoral, external iliac, superficial and deep femoral vein and popliteal vein were enlarged and contained with echogenous clot. He was treated with rifampicin 600 mg once a day, doxycycline 100 mg twice a day (both for three months) and amikacin 500 mg twice a day (for 2 weeks) accompanied with anti-coagulant. Ten days after the onset of this treatment, thrombophlebitis was cured. The follow up of the patient showed no abnormality after approximately one year later. CONCLUSION: In brucellosis endemic areas, the clinicians who encounter patients with deep vein thrombosis and current history of a febrile illness, should consider the likelihood of brucellosis.
RESUMO
BACKGROUND: Thrombocytopenia is associated with a bad prognosis in Leptospirosis. OBJECTIVES: We investigated the effect of corticosteroids to improve thrombocytopenia due to leptospirosis. PATIENTS AND METHODS: In a clinical trial, all patients admitted with leptospirosis in Razi Hospital of Ghaemshahr, north of Iran were enrolled in a 2-year study. Totally, 56 patients with moderate to severe thrombocytopenia were randomized to control and treatment groups. The treatment group received corticosteroid (prednisolone 1 mg/kg/day for maximum one week) in addition to the standard antibiotic therapy. RESULTS: There was no significant difference regarding age and gender between the two groups (P = 0.254, P = 0.789, respectively). The mean duration to improve thrombocytopenia was 4.41 ± 0.197 days in the treatment group and 5.72 ± 0.318 days in the control group, which was significantly different (P = 0.003). Duration of hospitalization in the treatment group was 5.24 ± 0.244 days and 6.23 ± 0.329 days in the control group, which was significantly different (P = 0.028). The two groups had no significant difference regarding mortality, intubation, level of platelet, duration of ICU admission and pulmonary, renal or hepatic involvement. CONCLUSIONS: Corticosteroid therapy decreased the length of hospitalization only in severe subgroup thrombocytopenia, but not in the moderate subgroup.
RESUMO
BACKGROUND: The antibiotic resistance of nosocomial organisms is rapidly increasing. The purpose of this study was to determine the frequency of bacterial agents isolated from patients with nosocomial infection. METHODS: This study was performed in the different wards of teaching hospitals of Mazandaran University of Medical Sciences (northern Iran). The study population consists of the patients with the symptoms of nosocomial infection admitted in these hospitals in 2012. The patient data (including age, sex, type of infection, type of isolated organisms and their antibiotic susceptibility) were collected and analyzed. RESULTS: The total number of hospitalizations was 57122 and the number of nosocomial infection was 592. The overall prevalence of nosocomial infection was 1.03% that was mostly in Burn unit and intensive care unit. The most common nosocomial infection was wound infection (44.6%) and the most common organisms were Pseudomonas aeruginosa and Acinetobacter. CONCLUSION: Given the increasing numbers of nosocomial infection in this region, especially infection with Pseudomonas aeruginosa, it is necessary to make a precise reporting and improve the procedures of infection control in hospitals.
RESUMO
INTRODUCTION: Fungal prosthetic valve endocarditis (PVE) is rare but serious complication of valve replacement surgery. Candida species, particularly Candida albicans is the most common isolated pathogen in fungal PVE (1-6%of cases). CASE PRESENTATION: We describe a 35-year-old woman who underwent mechanical mitral valve replacement about 3 years ago. She was admitted with neurological symptoms and later with dyspnea and hypotension. Transesophageal echocardiography showed large and mobile prosthetic valve vegetation. She underwent mitral valve surgery. The explanted valve and vegetation revealed lots of budding yeasts and the isolated yeast was identified as C. parapsilosis. Amphotericin B and broad spectrum antibiotic were started immediately. Unfortunately, the patient died two days after surgery, due to sepsis probably related to the candidemia. CONCLUSIONS: Fungal endocarditis is uncommon infection, but it is a serious problem in patients with prosthetic valve. Fungal PVE can occur years after the surgery, thus long-term follow-up is essential.
RESUMO
UNLABELLED: Background : Cefepime was used as empirical treatment in ventilator-associated pneumonia (VAP) induced by gram-negative and gram-positive bacteria. This study aimed to determine the antimicrobial susceptibility pattern of cefepime against microorganism causing VAP in Mazandaran, North of Iran. METHODS: This study was performed on VAP patients diagnosed with clinical pulmonary infection score (CPIS) scores in ICU of two hospitals. For each patient suspected of having VAP, quantitative culture of endotracheal aspiration (QEA) was performed and MIC was determined by micro dilution test. Data were collected and analyzed. RESULTS: Thirty- five cases of enterobacteriaceae were isolated orderly including E coli 13, P. aeruginosa 11, Enterobacter 7 and K. pneumonia 4 cases. All the isolated E. coli, Enterobacter and Klebsiella, 54.5% of P. aeruginosa isolated were fully resistant to cefepime. CONCLUSION: The results of this study show that cefepime is not a reasonable choice for empirical treatment of nosocomial pneumonia and VAP.
RESUMO
An Aspergillus fungal ball is a rare cause of ureteral obstruction attributed to indwelling catheters, stents, antibiotics, anastomotic leaks, obstruction, and immunosuppressive therapy and other immunocompromised states. We describe a case of unilateral ureteral obstruction caused by Aspergillus terreus following ureteroscopic lithotripsy and ureteral stenting in a 45-year-old diabetic man. The patient was successfully treated with endoscopic removal of the fungal mass and oral voriconazole. We also review briefly the clinical features, treatment, and outcome in 9 previously reported diabetic patients with ureteral obstruction due to aspergillosis. Obstructive uropathy related to Aspergillus mass may be suspected in diabetic patients with a history of manipulation, impaired kidney function, and persistent passage of a soft mass in urine. Direct microscopy and culture of multiple urine and ureteral washing are necessary for early diagnosis. Antifungal therapy and endoscopic removal of the mass are needed to reduce morbidity.

BACKGROUND: The clinical manifestations and outcome of influenza infection differ between various patients in the world. The purpose of this study was to assess the clinical manifestations of patients with confirmed or suspected novel H1N1 flu infection in Sari, North of Iran. METHODS: From September 2009 to January 2010, the patients' data were collected by retrospective chart review of medical records. Laboratory confirmation included a positive RT-PCR (reverse transcriptase-polymerase-chain-reaction assay) from a nasal or pharyngeal swab sample. RESULTS: Nearly 80% of established patients were in age group of 15-45 years. Approximately 14.6% of female cases were pregnant There was no significant difference in clinical and laboratory characteristics of patients with confirmed H1N1 virus infection to total cases with Influenza Like Illness (ILI). Thirty nine (95.1%) of the established patients had a combination of fever plus sore throat or cough. Relative lymphopenia was reported in 36.6%. Pneumonia was the most common complication. Acute pericarditis evolved in one case and aseptic meningitis was reported in another. CONCLUSION: Precise collecting information of clinical manifestations, risk factors and other characteristics of flu, can help to the early infection detection, timely treatment of patients and proper preventive measurements.
RESUMO
BACKGROUND: Brucella epididymoorchitis(BEO) is a focal complication of human brucellosis and has been reported in 2-20% of patients with brucellosis. Brucellosis is an endemic disease in Iran. The incidence of the disease in this country is 34 per 100 000 per year. METHODS: In a retrospective study, we identified 30 cases of Brucella epididymoorchitis in two teaching hospitals in the north of Iran during 1997-2009. FINDINGS: Epididymoorchitis occurred in 11.1% of male patients with brucellosis. The average age was 25.5 ± 12.43 years. Pain and scrotal swelling (100%) and fever (96.7%) were the most common symptoms. Different treatment regimens were administered including doxycycline plus rifampin (60%), doxycycline plus rifampin plus aminoglycoside for the first two weeks (36.6%) and doxycycline plus cotrimoxazole(3.4%). Ten percent of the patients did not respond to antibiotic therapy and required surgical drainage or orchiectomy. CONCLUSIONS: In brucellosis endemic areas, clinicians who encounter patients with epididymoorchitis should consider the likelihood of brucellosis. A careful history and physical examination and an immediate laboratory evaluation help to make a correct diagnosis. Generally, classical therapy of brucellosis is adequate for the treatment of epididymoorchitis.
