  • Determination of The Relationship Between Severity of Obstructive Sleep
           Apnea And Chronic ...

    • Abstract: Introduction: Chronic obstructive pulmonary disease (COPD) patients are at increased risk of sleep-disorders. The concomitant occurrence of COPD and obstructive sleep apnea hypopnea syndrome (OSAHS) is named overlap syndrome. This study aimed to evaluate the severity of OSAHS in overlap syndrome patients.Materials & Methods: This cross-sectional study was conducted on adult patients with forced expiratory volume in 1 second (FEV1%)/forced vital capacityResults: Forty patients (62.5% male) with mean age of 59.7±8.3 years participated in the study. Severity of obstructive sleep apnea was low, moderate, and severe in 23 (57.5%), 14 (35%), and 3 (7.5%) cases, respectively and there was no statistical relation between OSAHS and FEV1% (P=0.55).Conclusion: This study showed that there was no significant correlation between apnea–hypopnea index and FEV1% predicted in overlap syndrome patients.

  • Frequency of Acute Kidney Injury in Patients Treated With Normal Saline
           after Off-Pump Coronary ...

    • Abstract: Introduction: Acute kidney injury (AKI) is a common postoperative complication of cardiac surgery, which is associated with an increased risk of morbidity and mortality. This study investigated the frequency of postoperative AKI in low risk adult patients undergoing off-pump coronary artery bypass grafting (CABG).Materials & Methods: All consecutive adult patients of American Society of Anesthesiologists (ASA) class II and III, who were transferred to the post-operative cardiac surgery ICU after off-pump CABG and were low risk for AKI from October 2013 to September 2014 at Emam Reza Hospital, Mashhad, Iran were enrolled in this prospective cohort study at a teaching hospital. The patients were explored for AKI development, based on risk-injury-failure-loss- end stage kidney disease (RIFLE) and acute kidney injury network (AKIN) criteria, frequency of metabolic acidosis, hypernatremia, hyperchloremia, and length of stay in ICU.Results: According to the results of the present study, 479 patients with the mean age of 60.8±10.75 yrs were included. AKI occurred in 22 (4.4%) and23 (4.8%) patients, based on both the RIFLE and AKIN criteria, respectively with the highest rate of AKI, reported on the third and fourth post-operative days. Additionally, hyperchloremia and hypernatremia were observed in 71 (14.8%) and 76 (15.9%) patients, respectively. Only one case of mortality occurred during the study. Metabolic acidosis was reported in 112 (23.4%) patients with a high anion gap in 60 (12.5%) cases.Conclusion: The current study demonstrated that hypernatremia and metabolic acidosis but not AKI are frequently seen in patients receiving normal saline following off pump CABG with low risk for AKI.

  • Video-assisted Thoracoscopic Surgery Versus Axillary Thoracotomy in
           Primary Spontaneous Pneumothorax

    • Abstract: Introduction: Video-assisted thoracic surgery (VATS) is now commonly used for primary spontaneous pneumothorax. In the present study we compared the outcomes of this technique with those obtained by conventional thoracotomy.Material and Methods: In this cross-sectional stud, forty patients were enrolled into two groups: VATS (n=20) and thoracotomy (n=20). In both groups the blebs were resected and pleural abrasion was performed with putting a mesh on the apical surface of the parietal pleura, finalized by patchy pleurectomy and mechanical abrasion with gas. Two groups were appropriately matched for age, gender, side of bleb, indication for surgery, and the smoking habits. As outcome measures, the conversion from VATS to thoracotomy and the early complications including wound infection, air leakage and intraoperative bleeding were assessed. After discharge, follow up schedule included visits at one, three, six months and one year post-operation to evaluate the recurrence rate.Results: Mean age of these forty patients (34 males and 6 females) was 28.4±8.74 years. There was no conversion from VATS to thoracotomy group. The complications, including prolonged air leakage and wound infection, were seen in three patients of each group (totally 6 patients) (P=0.712). One patient in VATS group experienced the recurrence (P=0.235). Average admission time was 5±0.79 days in the VATS and 5.65±0.81 days in the thoracotomy group (P=0.043), duration of surgery in the open thoracotomy and VATS groups were 76±5.52 and 48.35±4.35 min, respectively (P<0.001) and intra-operative bleeding in the open thoracotomy and VATS groups were 127.5±10.69 and 112.5±8.5 mL, respectively (P<0.001) these three factors were significantly less in the VATS group.Conclusion: VATS seems to be superior to thoracotomy, when it is indicated due to the recurrence or other reasons, because in spite of the similar therapeutic efficacy and recurrence rate, VATS is associated with less tissue damage and shorter hospital stay.

  • Avoidance of Dialysis in an End-Stage Renal Disease Patient Status-post
           Off-pump Coronary ...

    • Abstract: Certain benefits are clearly associated with the use of off-pump coronary artery bypass grafting (CABG) as compared with the on-pump CABG. The superiority is more evident in patients with multiple co morbidities including renal failure.We reviewed the medical records of a 67-year-old male with a past medical history that was significant for multiple cardiovascular diseases and new-onset end-stage renal disease. The case was suffering from dyspnea and work-up was suggestive of non-ST elevation myocardial infarction and congestive heart failure.During the hospital course, he developed end-stage renal disease requiring hemodialysis. Further cardiac evaluation presented three-vessel coronary artery disease. The patient underwent off-pump CABG. Post-operatively, the patient had minimal complications and did not receive hemodialysis for 53 days.Off-pump CABG has evident short-term benefits for patients with the end-stage renal disease requiring dialysis, including possible improvement in cardiac function and avoidance of hemodialysis

  • Intracardiac Ifection at the Tip of Hemodialysis Catheter: Life
           threatening Morbidity

    • Abstract: Endocarditis and intracardiac infection have been increased recently especially in dialysis dependent renal failure patients. This is usually intractable infection to broad spectrum Antibiotic therapy and in most cases surgical intervention was necessary. We have presented 45 years old man with intracardiac infection at the tip of dialysis catheter that after catheter removal intracardiac infection was removed.

  • Malignant Fibrous Histiocytoma of the Lung: A Case Report

    • Abstract: Malignant Fibrous Histiocytoma (MFH) is the most common soft-tissue sarcoma which predominantly surfaces in the retro-peritoneum and extremity. MFH of lung is a very rare condition. The diagnosis is essentially through histologic examination. However, the invasion of the chest wall or other organs might help establish the malignant nature.We report a case of a 77-year-old man who had been presented with a history of dyspnea and non-massive hemoptysis. Computed Tomography (CT) scan of the chest showed a lobulated mass which had developed into the hilum of the lung. Furthermore, the inferior pulmonary artery was invaded. Thus, the final histological diagnosis confirmed MFH. The patient underwent a left pneumonectomy along with the dissection of the regional lymph nodes. Although lung MFH is rather an uncommon condition, it must be taken into consideration in differentiating between the types of lung tumor. What can be concluded is that complete surgical resection is the essential approach.

  • Three Different Imaging Modalities of a Patient with the Aortic

    • Abstract: The patient was a 19 year-old woman with the diagnosis of resistant hypertension, although she was under treatment of three classes of anti-hypertensive drugs (beta blocker, angiotensin receptor blocker, diuretic) for more than one year. In physical examination there was only a significant difference between the systolic blood pressure of upper and lower extremities (200 vs. 120 mmHg), without any other remarkable finding. Three different imaging modalities (echocardiography (Figure 1), CT angiography (Figure 2), conventional aortography (Figure 3) confirmed the aortic coarctation at 30 mm after left subclavian artery origin, with the 3.5-4 mm diameter of the narrowest segment. She underwent implantation of a self-expanding aortic stent and therefore the systolic pressure gradient decreased from 90 to 15 mmHg. After three months, her blood pressure was stable on 110/80 mmHg, while she received only metoprolol 25 mg twice daily and follow-up echocardiography showed 15-20 mmHg pressure gradient through the stent.

  • Recurrent Venous Thromboembolism as the Initial Clinical Presentation of
           Gastric Cancer: A Case ...

    • Abstract: Pulmonary thromboembolism (PTE) is a clinically critical disease misdiagnosis or delayed diagnosis of which can lead to increased rate of mortality (1). For prevention of recurrence of PTE, recognition of its risk factors or underlying diseases is of great importance. PTE is common in patients with cancer and has high morbidity and mortality rates. Although cancer is a lethal condition, PTE accelerates death in these patients (2, 3). In the current study, we reported the case of a 50-year-old male presenting with dyspnea, pleuritic chest pain, and non-massive hemoptysis indicating pulmonary embolism. Anticoagulant therapy was initiated, but after 12 days of treatment, new deep vein thromboses in the left upper and right lower limbs were diagnosed. However, no specific risk factors or laboratory abnormalities were detected. History of weight loss during the recent months encouraged further investigation for ruling out malignancy, which led to diagnosis of gastric adenocarcinoma in upper endoscopy that was pathologically confirmed. He did not have any complaints of gastrointestinal disorders.

  • A case report of recurrent rheumatic fever in older young female:
           considerations and comments

    • Abstract: Rheumatic fever (RF) is a prevalent healthcare problem in developing countries. Recurrence of this disorder often can be seen in older young and children and is not frequent in older age. RF can mimic the presentations of infective endocarditis and clinicians is not really familiar with this issue. We showed a case of recurrent acute rheumatic fever in a patient was suspicious to acute bacterial endocarditis due to her previous RF. She finally was definitively diagnosed and underwent valvular replacement surgery and received prophylaxis antibiotic beside regular follow up.
