Arthroscopic Posteromedial Corner Reconstruction: A Novel Technique and Case Series.

Objectives: This study aimed to introduce a novel arthroscopic treatment for medial and posteromedial instability of the knee and present the primary and follow-up results. Methods: All patients who underwent the arthroscopic approach to treat medial and posteromedial corner instability from 2007 to 2017 were included in this report. Overall, 45 patients were included, among which 75.6% were male. The mean age of patients was 32.2 ± 8.4 years. Overall, 44.4% and 15.6% of patients had associated meniscal injuries and chondral lesions, respectively. The mean follow-up duration of patients was 84.2 ± 25.3 months. Results: Overall, 37 patients developed a full range of motion (82.2%), and most patients (95.6%) showed excellent quadriceps strength (grades 4 and 5). All patients had a normal or 1+ posterior drawer test, Pivot shift test, and Lachman test on physical examination. Moreover, 60% had an associated isolated anterior cruciate ligament injury, 17.8% had an isolated posterior collateral ligament injury, and 17.6% had a combination of more than one ligament injury. One patient developed septic arthritis. Two patients experienced pain, and one pain patient developed pain with a bony spur formation in the medial epicondyle. Three patients showed a 2+ medial collateral ligament (MCL) test (moderate instability) at the final follow-up, all of whom had multi-ligament injuries. All patients, except the three patients who had a failed MCL reconstruction, returned to their previous activities. Conclusion: This study described a novel arthroscopic treatment of MCL injury, and the results showed acceptable postoperative and clinical outcomes. As the use of minimally invasive surgery may minimize multiple complications associated with open surgery, it is suggested that further studies be conducted regarding this approach when faced with patients who have MCL injuries requiring surgery.

Two-Year Functional Outcomes of Nonsurgical Treatment in Concomitant Anterior Cruciate Ligament and Medial Collateral Ligament Injuries: A Case-Control Study.

The anterior cruciate ligament (ACL) is a common knee injury in high-intensity sports, which can cause early career loss in young athletes. Concomitant damage to other knee stabilizers may occur, such as the medial collateral ligament (MCL). Recent studies have shown that knee stability can increase without surgical intervention in patients with ACL and MCL injuries. Regarding the importance of functional tests in return to exercise prediction, this study aims to measure nonsurgical approach's long-term outcome for concomitant ACL and MCL injuries with a focus on functional tests. This is a case-control study with a 2-year follow-up. The case group consisted of patients who had provided written consent and completed their 2-year follow-up, and the control group was made up of healthy people who did not have any knee medical conditions and were matched by age, gender, and activity level. Physical examinations, Tegner and International Knee Documentation Committee questionnaires, and knee magnetic resonance imaging were conducted, and functional performance tests were performed after a 10-minute warm-up. Lody's index (the ratio of injured-to-uninjured knee results) was calculated. The data were analyzed using independent t-test, one-way analysis of variance, chi-squared test, and Fisher's exact test. The study involved 11 patients in each concomitant ACL and MCL injury cases and healthy control groups with a mean age of 32.4 and 28 years, respectively. None of the patients reported knee instability symptoms in the 2-year follow-up. More than half of the patients continued their sports field without reinjury, with no significant difference in activity levels between case and control groups. The 6-meter hop test and single-leg hop test showed no significant difference between case and control groups (p-value: 0.326, 0.859), and no significant difference was observed in the three Carioca, cocontraction, and Shuttle tests in the 2-year follow-up. Functional tests in ACL and MCL injuries revealed normal outcomes, implying a nonsurgical approach for patients with proximal ACL tears, better knee stability, and no significant differences between the injured and control groups.

Acute Irreducible Rotational Patellar Dislocation with Patellar Tendon Rupture: A Case Report.

CASE: In this report, we present a case of acute patellar dislocation with both vertical and longitudinal rotation of the patella. As a result of rotation in the longitudinal axis, the articular surface of the patella faced outward, and the dorsal surface faced the femoral condyle. The patient underwent open reduction. One year after open reduction and soft-tissue repair, the patient had acceptable knee function and no knee pain. CONCLUSION: This case shows how similar cases may be treated with an open reduction to properly address the patellar dislocation.

Epidemiology of obesity and high blood pressure among school-age children from military families: the largest report from our region.

BACKGROUND: For the first time, we aimed to determine the epidemiology and associated factors of obesity and hypertension among children of military families in our region. METHODS: In this multi-centered study, children between the ages of 5 to 12 years old, entered the study. Data on baseline and clinical characteristics, history of disease and anthropometric measurements, were collected. RESULTS: Among 504 children, 44.2% were males. Mean (SD) age of participants was 7.9 ± 1.9 years. Overall, 5% were obese and 9.9% were overweight. In total, 16.3% had elevated BP, 12.5% had stage one and 0.2% had stage two hypertension. Age (beta = 0.306, OR = 1.35, 95% CI:1.14-1.61), obesity/overweight (OR = 5.58, 95% CI:2.59-12.0), history of hypertension in mother (OR = 43.24, 95% CI:5.99-312.11), low birth weight (OR = 7.96, 95% CI:2.59-12.0), physical activity (OR = 0.27, 95% CI:0.10-0.72), and consumption of fast food more than once a week (OR = 3.36, 95% CI:1.82-6.19), were associated with risk of hypertension. Furthermore, age (beta = 0.346, OR = 1.41, 95% CI:1.21-1.64), history of childhood obesity in the father (OR = 3.78, 95% CI: 1.77-8.06) and mother (OR = 2.44, 95% CI:1.07-5.56), and physical activity (OR = 0.27, 95% CI:0.11-0.66), were associated with obesity. CONCLUSION: Age, obesity/overweight, history of hypertension in the mother, birth weight, physical activity, and consumption of fast food, were associated with risk of hypertension. Moreover, age, history of childhood obesity in parents, and physical activity, were associated with obesity. Furthermore, we found that school-age children in military families have higher rates of hypertension and overweight compared to other reports from our region.

Intestinal Transplantation in a Country Without Home Parenteral Nutrition: The Largest Report from the Middle East.

BACKGROUND: Many regions of the world, especially middle- and low-income countries, lack facilities for home parenteral nutrition and thus cannot follow existing guidelines for intestinal transplantation. Herein, we report our experiences with treatment protocols, intraoperative management, and early postoperative outcomes among patients undergoing either isolated intestinal transplantation or multivisceral transplantation in our center. METHODS: During a 1-year period from March 2019 to March 2020, a total of 9 intestinal transplantations including 6 isolated intestinal transplantations and 3 multivisceral transplantations were performed in our center. We reported on donor selection strategies, surgical treatment, anesthesiology care and protocols for total parenteral nutrition, immunosuppression regimen, and pathology evaluation. RESULTS: Mean (standard deviation) age of patients was 37.5 ± 12.5 years. The majority of patients were females (7/9). The median (interquartile range) waiting time for patients from diagnosis to transplantation was 79 (34, 164) days. Our 7-day survey of the amount of fluid therapy after transplantation revealed that the greatest need for fluid therapy was seen on the second postoperative day. After transplantation, 2 patients showed a total of 3 episodes of severe rejection, 1 of which was antibody-mediated. The 1-year survival was 66.6% and the 2-year survival was 44.5% in our study population. The median (interquartile range) time to death was 157 (26.5, 382) days. The most common cause of death was sepsis in our series (3/5). CONCLUSION: Acceptable outcomes can be obtained with intestinal transplantation in countries without home parenteral nutrition by application of specific treatment protocols.

Using Doppler sonography resistive index for the diagnosis of perinatal asphyxia: a multi-centered study.

BACKGROUND AND OBJECTIVE: Inhere we evaluated the diagnostic utility of Doppler sonography (DS) of the anterior cerebral artery (ACA), middle cerebral artery (MCA) and the basilar arteries (BA) based on resistive index (RI) for the diagnosis of asphyxia. METHODS: In this multi-centered cross-sectional study, neonates with clinical diagnosis of asphyxia, were considered for study. During the first 24 h, neonates underwent DS. MRI was done for each neonate during the first month, after discharge or during hospital admission, after obtaining clinical stability. Staging based on DS was compared with staging based on MRI. RESULTS: Overall, 34 patients entered the study. DS of the ACA, MCA, BA all had significant correlation with MRI findings (regarding severity of asphyxia) (r > 0.8 and p < 0.001). In the receiver-operating-characteristic analysis, ideal cut-off point for diagnoses of asphyxia based on ACA and BA was RI ≤ 0.62 [area under the curve (AUC) = 0.957 and 95% CI: 0.819-0.997; sensitivity = 95.65; specificity = 100; positive predictive value (PPV) = 100; negative predictive value (NPV) = 90.9 and negative likelihood ratio (NLR) = 0.043]. Regarding MCA, similarly, a RI ≤ 0.62 was ideal for differentiating between normal and asphyxiated neonates (AUC = 0.990 and 95% CI: 0.873-1; sensitivity = 91.30; specificity = 100; PPV = 91.2; NPV = 100 and NLR = 0.087). CONCLUSION: For evaluating neonates clinically suspected of asphyxia, especially in centers with limited facilities such as MRI, DS can be used as a first line diagnostic modality and RI of ≤ 0.62 is an appropriate cut-off for the diagnosis of perinatal asphyxia.

Update on surgical management of enteroatmospheric fistulae in intestinal failure patients.

PURPOSE OF REVIEW: The surgical management of enteroatmospheric fistula (EAF) in patients with intestinal failure represents a major challenge for a surgical team and requires proficiency in sepsis management, nutritional support and prehabilitation, beside expertise in visceral and abdominal wall surgery. This review provides an update on the current recommendations and evidence. RECENT FINDINGS: Reconstructive surgery should be performed at a minimum of 6-12 months after last laparotomy. Isolation techniques and new occlusion devices may accelerate spontaneous EAF closure in selected cases. Chyme reinfusion supports enteral and parenteral nutrition. Stapler anastomosis and failure to close the fascia increase the risk of EAF recurrence. Posterior component separation, intraoperative fascial tension and biological meshes may be used to accommodate fascial closure. SUMMARY: Timing of reconstructive surgery and previous optimal conservative treatment is vital for favorable outcomes. Wound conditions, nutritional support and general patient status should be optimal before attempting a definitive fistula takedown. Single stage procedures with autologous gut reconstruction and abdominal wall reconstruction can be complex but well tolerated.

Periodic fever, aphthous stomatitis, pharyngitis, and cervical adenitis syndrome (PFAPA) or recurrent urinary tract infections: a case report.

BACKGROUND: Fever is the most frequent reason for medical consultation in children, and makes up 15-25% of all consultations in primary care and emergency departments. In here we report a case of a 13 year-old girl who referred with an unusual presentation of fever and was misdiagnosed with recurrent urinary tract infection for 8 years. CASE PRESENTATION: This is a Clinical Reasoning Cycle case study. A 13 year-old girl was referred with a chief complaint of recurrent fevers from 8 years. During her first febrile episode, she had a 5-day high-grade fever associated with loss of appetite. Her physical examination at that time was unremarkable. Blood tests showed leukocytosis with a shift to the left and urine examination was in favor of pyuria. The urine culture was positive for bacterial growth. The episodes of fever were repeated every 45 days. Accordingly, the patient was diagnosed as a case of recurrent urinary tract infection. In the intervals between her febrile episodes, the patient was healthy and laboratory tests were normal. Ultrasonography, voiding cystourethrogram and dimercaptosuccinic acid scans were normal. During her last visit, the patient mentioned difficulty in swallowing and on examination cervical lymph nodes, exudative tonsillitis and painful aphthous stomatitis were detected. All antibiotics were stopped and corticosteroids were started. The patient's symptoms were relieved and the interval between her febrile episodes became longer. CONCLUSIONS: Our study shows that a patient should never be marked, particularly when the symptom and signs aren't completely justifying a patient's condition.

Intraoperative radiation therapy for early stage breast cancer.

BACKGROUND AND OBJECTIVE: We report our experiences with Intraoperative radiation therapy (IORT) among breast cancer (BC) patients in our region. METHODS: All patients who received radical IORT from April 2014 on to March 2020 were included in the study. Patient selection criteria included: Age equal or older than 45 years old; All cases of invasive carcinomas (in cases of lobular carcinomas only with MRI and confirmation); Patients who were 45-50 years old with a tumor size of 0-2 cm, 50-55 years old with a tumor size of < 2.5 cm, and those who were ≥ 55 years old with a tumor size of < 3 cm; Invasive tumors only with a negative margin; Negative nodal status (exception in patients with micrometastasis); A positive estrogen receptor status. Primary endpoints included death and recurrence which were assessed using the Kaplan-Meier method. RESULTS: Overall, 252 patients entered the study. Mean (SD) age of patients was 56.43 ± 7.79 years. In total, 32.9% of patients had a family history of BC. Mean (SD) tumor size was 1.56 ± 0.55 cm. Mean (IQR) follow-up of patients was 36.3 ± 18.7 months. Overall, 8 patients (3.1%) experienced recurrence in follow-up visits (disease-free-survival of 96.1%), among which four (1.5%) were local recurrence, two (0.8%) were regional recurrence and two patients (0.8%) had metastasis. Median (IQR) time to recurrence was 46 (22, 53.7) months among the eight patient who had recurrence. Overall, one patient died due to metastasis in our series. Eleven patients (4.3%) with DCIS in our study received IORT. All these patients had free margins in histopathology examination and none experienced recurrence. CONCLUSION: Inhere we reported our experience with the use of IORT in a region where facilities for IORT are limited using our modified criteria for patient selection.

Experiences with intestinal failure from an intestinal rehabilitation unit in a country without home parenteral nutrition.

OBJECTIVE: For the first time, we reported experiences with an intestinal rehabilitation unit (IRU) from a country without home parenteral nutrition (HPN). METHODS: We included patients with a diagnosis of intestinal failure (IF) since the establishment of our IRU from February 2018 to February 2020. We further report on our protocols for management of enterocutaneous fistulas (ECFs), short-bowel syndrome (SBS), chronic intestinal pseudo-obstruction and motility disorders. RESULTS: Among a total of 349 patients who have been admitted, 100 patients had IF and were included . Mean (SD) age of patients was 46.3 ± 16.1 years. Most common cause of IF was ECFs (32%), SBS (24%), and SBS + fistula (22%). Most common causes of SBS were mesenteric ischemia (63.3%) and repeated surgery (22.4%). Median (interquartile range [IQR]) duration of parenteral nutrition (PN) for patients was 32 (18-60) days. The most common reconstructive surgery performed was resection and anastomosis (75.4%), followed by serial transverse enteroplasty procedure (10.5%) and closure of ostoma (7%). Patients were hospitalized for a median (IQR) of 33 (17.5-61) days. Most common complications were sepsis (45%), catheter infections (43%), and catheter thrombosis (20%), respectively. At the final follow-up, 61% stopped receiving PN, 23% became candidates for transplantation, and 16% died. CONCLUSION: Considering that most countries lack facilities for HPN, by establishing IRUs using specific treatment protocols and autologous gastrointestinal reconstruction techniques will provide a means to manage patients with IF, thus decreasing death rates and number of patients who require intestinal transplantations due to IF.

How accurate is frozen section pathology compared to permanent pathology in detecting involved margins and lymph nodes in breast cancer?

BACKGROUND: Frozen section (FS) pathology has multiple limitations, and different institutions report variable experiences with the use of FS for diagnosis of tumor involvement. We aimed to compare the FS accuracy with that of permanent pathology (gold standard) regarding marginal involvement and lymph node status using data from the largest breast cancer registry in Iran. METHODS: In this retrospective study, women who had both FS and permanent pathology reports were included. The two pathology reports were cross compared with regard to the involvement of tumor margins and sentinel lymph nodes. RESULTS: Overall, 2786 patients entered the study. Mean age of patients was 48.96±11.44 years. A total of 1742 margins were analyzed. Accordingly, sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of FS pathology for detection of involvement of involved margins were 78.49%, 97.63%, 65.1%, and 98.7%, respectively. The accuracy and area under the curve (AUC) for FS pathology were 96.61% and 0.73 (95% CI: 0.64-0.831), respectively. A total of 1702 sentinel lymph node biopsies were assessed. Sensitivity, specificity, PPV, and NPV, of FS pathology for detection of lymph node involvement, were 87.1%, 98%, 95.5%, and 93.3%, respectively. Accuracy and AUC of FS for diagnosis of involved lymph nodes were 94.1% and 0.926 (95% CI: 0.909-0.942), respectively. CONCLUSION: Frozen pathology is a suitable method for identifying involved sentinel lymph nodes in patients with breast cancer, but this method has a less than optimum efficacy for detecting and confirming marginal involvement.

Oral Health Status in the Pars Cohort Study.

BACKGROUND: Poor oral health is common in the world, especially in low-income and developing countries. We evaluated oral health status and its association with sociodemographic and economic variables in one of the largest cohort studies in Iran. METHODS: This cross-sectional study was conducted using data from the Pars Cohort Study which is conducted in a rural area in southern Iran. A total of 9264 individuals were enrolled in the initial registry. Data on sociodemographic and clinical characteristics were collected. Oral assessment was completed by trained physicians. Generalized negative binomial regression modeling was applied. RESULTS: Overall, data from 9264 participants entered the final analysis. The participants' mean age was 52.6 ± 9.7 years. In total, 8975 participants (96.8%) had at least one tooth loss and 1790 participants (19.3%) were edentulous. Female gender (incidence rate ratio [IRR]: 1.05, 95% CI: 1.02, 1.08) (IRR: 1.12, 95% CI: 1.07, 1.16), opium consumption (IRR: 1.17, 95% CI: 1.12, 1.22) (IRR: 1.23, 95% CI: 1.16 1.30), lower socioeconomic status (SES) (IRR: 1.07, 95% CI: 1.03, 1.10) (IRR: 1.10, 95% CI: 1.06, 1.15) and being illiterate (IRR: 1.23, 95% CI: 1.20, 1.26) (IRR: 1.36, 95% CI: 1.32, 1.41) were associated with higher decayed, missing and filled teeth (DMFT) and more tooth loss. CONCLUSION: Oral health was poor in our study sample, especially among older individuals, people with lower SES, illiterate participants, smokers and opiate consumers, which shows the need for improvement in oral health care.

Determinants of Prognosis in Triple-Negative Breast Cancer: Report from a Large Breast Cancer Registry.

BACKGROUND: The outcome of patients with triple-negative breast cancer (TNBC) is highly dependent on demographic factors and ethnicity. We aimed to evaluate the clinicopathological determinants of prognosis among women with TNBC using data from one of the largest breast cancer (BC) registries. METHODS: A total of 6145 patients with BC from our referral center were evaluated from 1995 to 2018, among whom 523 had TNBC. The baseline, menstrual and reproductive, treatment and pathology related characteristics were evaluated. RESULTS: Among TNBC patients, the rate of stage 3 and 4 BC (29.9% vs. 14.4% and 7.8% vs. 0% for stage 3 and 4, respectively; P<0.001), invasive ductal carcinoma (90.7% vs. 75.6%; P=0.004), nodal involvement (46.7% vs. 33.4%; P=0.026), mastectomy (57.3% vs. 37.8%; P=0.001) and axillary node dissection (76.7% vs. 59.8%; P=0.019) was significantly higher in the group that developed recurrence. Disease-free-survival was 80.6% (157.76 ± 9.48 months) and overall-survival was 90.1% (182.73 ± 3.28 months). For death, stage 3 BC (compared to stages 0 and 1 as base) showed a higher risk of earlier death (adjusted HR: 4.191, 95% CI=1.392-12.621; P=0.011). For recurrence, stage 3 BC (adjusted HR: 1.044, 95% CI=1.209-6.673; P=0.017) (compared to stages 0 and 1 as base) showed significantly higher risk for developing earlier recurrence. Moreover, those who had invasive ductal carcinoma (compared to other types of BCs) had a higher risk for developing earlier recurrence (adjusted HR: 3.307, 95% CI=1.191-0.724; P=0.012). CONCLUSION: BC stage plays a significant role in both earlier recurrence and earlier mortality among patients with TNBC.

Surgical Management of Intestinal Failure; Initial Experiences from an Intestinal Failure, Rehabilitation and Transplant Unit in Iran.

BACKGROUND: Intestinal failure (IF) is a life-threatening medical condition. The management of IF in low- and middle-income countries without home parenteral nutrition (HPN) remains unclear. We recently established an intestinal rehabilitation unit (IRU) and aimed to provide our experience on the current management and outcomes of IF in Iran. METHODS: In this cross-sectional case series, data were collected from an established database on IF in the Shiraz Transplant Center in Abu Ali Sina hospital, affiliated to Shiraz University of Medical Sciences, Iran from January 2018 to October 2018. RESULTS: Overall, 30 patients with a mean age of 44.13 ± 10.32 years, which included 25 males, were recruited. Short bowel syndrome (SBS) (60%) and enterocutaneous fistulae (27%), as complication of previous surgeries, were the main causes of IF. The most common type of IF was type 3 (67 %). Mesenteric ischemia was the leading mechanism of IF (47%). Fifteen patients (50%) received autologous gastrointestinal reconstruction surgery (AGIRS), and two (7%) patients had serial transverse enteroplasty (STEP). At the end of follow-up, 15 patients recovered from IF (50%). The overall survival rate was 83.3%. CONCLUSION: This series introduced the results of a multidisciplinary program for the treatment of IF in a middle-income country that lacks facilities for HPN. Our protocol of care, understanding the need for development of HPN, showed promising clinical outcomes.

Corticosteroids or platelet-rich plasma injections for rotator cuff tendinopathy: a randomized clinical trial study.

BACKGROUND: Studies evaluating the role of both corticosteroids and platelet-rich plasma (PRP) in the treatment of rotator cuff (RC) tendinopathies have been contradicting. We compared structural and clinical changes in RC muscles after corticosteroids and PRP injections. METHODS: This is a randomized double-blind clinical trial. All individuals with diagnosis of RC tendinitis during 2014-2017 were considered. Individuals were randomly allocated to either receive PRP or corticosteroids. Overall, 3cc of PRP was injected within the subacromial joint and another 3cc was injected at the site of the tendon tear, under the guide of sonography. For the corticosteroid group, 1cc of Depo-medrol 40mg and 1cc of lidocaine (2%) was injected within the subacromial joint. RESULTS: Overall, 58 patients entered the study. Comparison of pain, range of motion (ROM), Western Ontario RC (WORC), Disability of Arm-Hand-Shoulder (DASH) scores, and supraspinatus thickness showed significant improvement during follow-ups in both groups (p<0.05). During 3 months of follow-up, pain improvement was significantly better within the PRP group during (from 6.66±2.26 to 3.08±2.14 and 5.53±1.80 to 3.88±1.99, respectively; p=0.023). Regarding ROM, the PRP group had significant improvement in adduction (20.50°±8.23° to 28°±3.61° and 23.21°±7.09° to 28.46°±4.18° for the PRP and corticosteroid groups, respectively; p=0.011) and external rotation (59.66°±23.81° to 76.66°±18.30° and 57.14°±24.69° to 65.57°±26.39°, for the PRP and corticosteroid groups, respectively; p=0.036) compared to the corticosteroid group. CONCLUSION: We found that PRP renders similar results to that of corticosteroids in most clinical aspects among patients with RC tendinopathies; however, pain and ROM may show more significant improvement with the use of PRP. Considering that the use of corticosteroids may be contraindicated in some patients and may be associated with the risk of tendon rupture, we suggest the use of PRP in place of corticosteroid-based injections among patients with RC tendinopathy. TRIAL REGISTRATION: Clinical trial registration code: IRCT201302174251N9.

COVID-19 among patients with orthopedic surgery: our experience from the Middle East.

BACKGROUND: We report our experiences with COVID-19 in one of the largest referral orthopedic centers in the Middle East and aimed to describe the epidemiology and clinical characteristics of these patients. METHODS: During February 20 and April 20, 2020, patients who underwent orthopedic surgery and healthcare staff who were in contact with these patients were screened for COVID-19. To identify patients who were in the incubation period of COVID-19 during their hospital stay, all patients were tested again for COVID-19 4 weeks after discharge. RESULTS: Overall, 1244 patients underwent orthopedic surgery (1123 emergency and 121 elective) during the study period. Overall, 17 patients were diagnosed with COVID-19 during hospital admission and seven after discharge. Among the total 24 patients with COVID-19, 15 were (62.5%) males with a mean (SD) age of 47.0±1.6 years old. Emergency surgeries were performed in 20 (83.3%) patients, and elective surgery was done in the remaining 4 patients which included one case of posterior spinal fusion, spondylolisthesis, acromioclavicular joint dislocation, and one case of leg necrosis. A considerable number of infections occurred in patients with intertrochanteric fractures (n=7, 29.2%), followed by pelvic fractures (n=2, 8.3%), humerus fractures (n=2, 8.3%), and tibial plateau fractures (n=2, 8.3%). Fever (n=11, 45.8%) and cough (n=10, 37.5%) were the most common symptoms among patients. Laboratory examinations showed leukopenia in 2 patients (8.3%) and lymphopenia in 4 (16.7%) patients. One patient with a history of cancer died 2 weeks after discharge due to myocardial infarction. Among hospital staff, 26 individuals contracted COVID-19 during the study period, which included 13 (50%) males. Physicians were the most commonly infected group (n = 11), followed by operation room technicians (n = 5), nurses (n = 4), and paramedics (n = 4). CONCLUSIONS: Patients who undergo surgical treatment for orthopedic problems, particularly lower limb fractures with limited ambulation, are at a higher risk of acquiring COVID-19 infections, although they may not be at higher risks for death compared to the general population. Orthopedic surgeons in particular and other hospital staff who are in close contact with these patients must be adequately trained and given appropriate personal protective equipment during the COVID-19 outbreak.

The Fasa Registry on Systolic Heart Failure (FaRSH): Feasibility Study and the First 5-year Reports.

Background: The literature on patients with heart failure (HF) from the Middle East, besides a few existing registries, is scarce. We report, for the first time in our country, a hospital-based registry for systolic HF. Materials and Methods: This was a web-based registry on HF, conducted in Vali-Asr Hospital affiliated with Fasa University of Medical Sciences, Fasa, Iran. The goal of this registry was to define overall baseline clinical characteristics and natural history of hospitalized patients with systolic HF, to evaluate current management schema and implementation of practice guidelines, and to determine the correlation between genetic predisposition environmental effects, individuals' characteristics of health, lifestyle, morbidity, and mortality in relation with the effects of medication. Results: To date, 2378 individuals with a mean of age 67.08±13.07 years have been registered. Among which, 1381 (58.07%) patients were diagnosed with denovo HF. Most of the patients (60.1%) were male, and 8.9% had admissions during the past 30 days. The most common causes of HF were ischemic heart disease (86.5%) and hypertension (5.3%). Most patients had NYHA class one (44.3%) and three (20.4%). Overall, near 30% had diabetes and more than 38% had hyperlipidemia. Most individuals have been not a history of cigarette smoking (68.7%) or water-pipe smoking (96.9%). Also, 22.2% were current opium users, and 3.2% were previous opium users. Conclusion: The findings of this registry could make a realistic view of HF as a chronic disease with a burden. Therefore, policymakers can design programs and guidelines to prevent disease and better survival and quality of life.

A Report of 85 Cases of COVID-19 and Abdominal Transplantation From a Single Center: What Are the Associated Factors With Death Among Organ Transplantation Patients.

BACKGROUND: In this study, we report the epidemiology of COVID-19 among recipients of organ transplantation and evaluate associated factors with death. METHODS: We screened 6969 patients who had organ transplantations in our center for COVID-19. Specific data on presentation, clinical course, treatment, and prognosis were acquired. RESULTS: We found 85 patients (66 liver, 16 kidney, 2 kidney-pancreas, and 1 liver-kidney recipient) who acquired COVID-19. Most common symptoms included fever (48.2%), cough (41.2%), myalgia (41.2%), and fatigue (40%). Dyspnea developed in 33% of patients. Overall, one-third of patients had an oxygen saturation of below 90% on admission. Patients were hospitalized for a median (interquartile range) of 9 (5, 13.7) days and had a 33.9% intensive care unit admission rate. Overall, 17 patients (20%) died, which included 31.3% of patients with kidney transplantations and 18.2% of patients with liver transplantations. All 4 pediatric patients in our series died. In our univariate analysis among adults, rates of leukopenia (38.4% versus 13.2%; P = 0.04), low albumin levels (53.8% versus 10.2%; P = 0.001), and shorter duration between transplantation and COVID-19 (P = 0.02), were higher among patients who died. In our least absolute shrinkage and selection operator regression model, low albumin levels (OR, 4.48; 95% confidence interval, 1.16-17.27) were associated with higher risk of death. CONCLUSIONS: This is the largest single-center report on abdominal transplantations and COVID-19. Liver and kidney transplant recipients have an increased risk of mortality compared with the general population due to COVID-19. More specifically, pediatric patients and those with low albumin levels are at higher risks of death due COVID-19.

Assessment of hydro-geochemical properties of groundwater under the effect of desalination wastewater discharge in an arid area.

Desalination to increase irrigation water supply for agricultural production is becoming important in water-scarce regions. While desalination has positive effects on the potential irrigation water quantity and quality, the technique may also be a considered potential source of groundwater pollution. The present study investigated the effects of desalination wastewater discharge on groundwater quality in an arid area in southern Iran for the 2012-2017 period. The chemical composition of the groundwater samples was evaluated considering pH, EC, Na+, Ca2+, Mg2+, SO42+, Cl-, and HCO3-. The suitability of groundwater for drinking and irrigation purposes as well as spatial pattern of groundwater pollution was analyzed. The results showed that mean concentration of Na+, Ca2+, Mg2+, SO42-, and Cl- in all investigated wells increased from 148, 94, 46, 247, and 257 mg/L in 2012 to 282, 146, 71, 319, and 582 mg/L in 2017, respectively. Using Gibb's diagram, it was shown that the groundwater quality is slightly alkaline and primarily controlled by evaporation. Based on our findings, about 78% of the study aquifer displayed groundwater with good to excellent water quality that can be used for drinking and irrigation purposes. However, the eastern part of the aquifer was classified as unsuitable for use due to the disposal of desalination plant wastewater. The spatial distribution of WQI and other indices such as SAR, TDS, and TH showed that groundwater in the eastern part of the aquifer has deteriorated since the establishment of the desalination plants. To reverse this trend, it is important to implement regulations against wastewater discharge from desalination plants.
