Ilknur Erdem,1 Senay Elbasan Omar,1 Ridvan Kara Ali,1 Hayati Gunes,2 Aynur Eren Topkaya2 1Department of Infectious Diseases, 2Department of Medical Microbiology, Faculty of Medicine, Namik Kemal University, Tekirdag, Turkey Objective: Infections are among the most important causes of morbidity and mortality in patients with systemic lupus erythematosus (SLE) but are rare initial presentation of the disease. Therefore, in this study, we describe a case of Streptococcus pneumoniae sepsis in a young woman with previously undiagnosed SLE. Case report: A 23-year-old female patient was admitted to our outpatient clinic complaining of high fever (40°C), chills, fatigue, generalized myalgia, and cough with brown sputum for 5 days. Blood cultures grew gram-positive coccus defined as S. pneumoniae using standard procedures. Antinuclear antibody was positive at a titer of 1/1,000, and anti-double-stranded DNA was positive at 984 IU/mL. She was diagnosed with SLE. Her respiratory symptoms and pleural effusion were considered to be due to pulmonary manifestation of SLE. Conclusion: The underlying immunosuppression caused by SLE could have predisposed the patient to invasive pneumococcal disease. It may also occur as a primary presenting feature, although a rare condition. Keywords: Streptococcus pneumoniae, sepsis, systemic lupus erythematosus

A century ago, cardiac injuries usually resulted in death. However, despite all the advances in medicine, these injuries still have high mortality and morbidity rates. In the present case, we describe a patient with a bullet injury to the right ventricle who survived at our hospital despite the limitations of our center with regard to modalities and equipment. A 30-year-old man was brought to our emergency department with a bullet wound to his left flank. He was hemodynamically unstable. After only 8 minutes in the hospital and without further investigations he was rushed to the operating room. During laparotomy, a clot was visible in the left diaphragm, which dislodged and caused extensive bleeding. The decision was made to perform a sternotomy in the absence of a sternal saw. An oblique 8-cm injury to the right ventricle was discovered following rapid exploration. It was repaired without the need for cardiopulmonary bypass surgery. After a few days in the hospital, the patient was discharged home. In the event of a penetrating cardiac injury, rapid decision-making is crucial for survival. Whenever possible, the patient should be transferred to the operating room, as emergency department thoracotomies are associated with a high mortality rate., Competing Interests: Conflicts of interest The authors have no conflicts of interest to declare., (© 2023 The Korean Society of Traumatology.)

Introduction: It is crucial to be aware of post-COVID-19 non-pulmonary complications. Avascular necrosis (AVN) is one of these complications. It should be noted that the risk of AVN persists in individuals who have recovered from the COVID-19 infection. The current study aims to report several cases of AVN after being infected with SARS-CoV-2., Materials and Methods: This is a single-centre retrospective case series conducted over a 2-year period (January 2021-December 2022) involving individuals who developed AVN after being infected with COVID-19., Result: The study included a total of 17 patients. The mean age of patients was 38.65±6.1 years. Twelve of them were male (70.6%) and five were female (29.4%), with a ratio of 3:1. The mean BMI of the patients was 28.3±2.4 kg/m 2 . Eleven (64.7%) patients reported administering steroid injections throughout the infection course. The mean interval between COVID-19 infection and presentation to the clinic was 6.53 months. The majority of patients (82.3%) complained of bilateral hip pain. Limping was observed in 47% of the cases. MRI showed AVN in all cases. Bilateral core decompression was performed in five cases (29.4%), total hip replacement in three cases (17.6%), and conservative treatment in nine cases (53%)., Conclusion: The ongoing pandemic may have many long-term sequelae. There is a risk of developing AVN after COVID-19., Competing Interests: The authors declare that they have no conflicts of interest.Sponsorships or competing interests that may be relevant to content are disclosed at the end of this article., (Copyright © 2023 The Author(s).

Background: Cardiac myxoma is a rare cardiac tumor that may be asymptomatic or can cause embolization or intracardiac obstruction, leading to heart failure, sudden cardiac death, and arrhythmia. This study aims to report an 11-year experience of a single center in the management of cardiac myxoma., Method: This study is a single-center retrospective case series. Eighty cases of cardiac myxoma were collected in Ibn Albitar's specialized center for cardiac surgery. Transthoracic echocardiography was used to make the preoperative diagnosis in all patients. The surgeries were undertaken through the standard approach of a median sternotomy. All four cardiac chambers were thoroughly explored for additional myxomas. The major objective of the operations was complete tumor resection., Result: The mean age of the patients was 46.3 years. Females (67.5%) were predominant over males (32.5%). Shortness of breath was the most common symptom (86.25%). The left atrium was the most affected site (83.75%), followed by the right atrium (13.75%). Coronary artery bypass grafting was required as the secondary or associated intervention in 19 (23.75%) cases. The recurrence rate was 11.25%, with a mortality rate of 3.75%., Conclusion: Recurrence and tumor embolism are risks of surgical intervention for myxoma. Good preparation using transthoracic echocardiography as a diagnostic tool and standard median sternotomy to complete resection of the tumors can decrease the rate of recurrence, embolism, and even mortality., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (© 2023 Alhasso, Ahmed, Mohammed-Saeed, Kakamad, Almodhaffer, Zaid, Abdullah, Ali, Kakamad, Omar, Abdalla, Mohammed and Mustafa.)

Primary cardiac tumors are extremely rare and cardiac hemangiomas comprise less than 3% of them. Presentation of such disease with recurrent pericardial effusion is even rarer. Our patient is known case of myelodysplastic syndrome and up to our knowledge there are no reported case in which cardiac hemangioma was diagnosed in a patient with myelodysplastic syndrome. This 64 years male patient presented to our department with recurrent pericardial effusion, diagnosis was a query after extensive work he was found to suffer from a cardiac tumor based on the pulmonary artery and right ventricle. We performed surgery for him on cardiopulmonary bypass and did complete resection of the mass for him and result of biopsy showed mixed hemangioma. Recurrent pericardial effusion is most commonly a sign of a malignancy. Even with advancement of medical technology diagnoses of cardiac hemangiomas are still difficult. Treatment and definitive diagnosis is still complete surgical resection and histopathological examination., (© 2023 The Authors. Published by Elsevier Inc. on behalf of University of Washington.)

Bronchogenic carcinoma comprises >90% of primary lung tumors. The present study aimed to estimate the profile of patients with bronchogenic carcinoma and assess the cancer resectability in newly diagnosed patients. This is a single-center retrospective review conducted over a period of 5 years. A total of 800 patients with bronchogenic carcinoma were included. The diagnoses were mostly proven with either cytological examination or histopathological diagnosis. Sputum analysis, cytological examination of pleural effusion and bronchoscopic examination were performed. Lymph node biopsy, minimally invasive procedures (mediastinoscopy and video-assisted thoracoscopic surgery), tru-cut biopsy or fine-needle aspiration was used to obtain the samples for diagnosis. The masses were removed by lobectomy and pneumonectomy. The age range was between 22 and 87 years, with a mean age of 62.95 years. Males represented the predominant sex. Most of the patients were smokers or ex-smokers. The most common symptom was a cough, followed by dyspnea. Chest radiography revealed abnormal findings in 699 patients. A bronchoscopic evaluation was performed for the majority of patients (n=633). Endobronchial masses and other suggestive malignancy findings were present in 473 patients (83.1%) of the 569 who underwent fiberoptic bronchoscopy. Cytological and/or histopathological samples of 581 patients (91.8%) were positive. Small cell lung cancer (SCLC) occurred in 38 patients (4.75%) and non-SCLC was detected in 762 patients (95.25%). Lobectomy was the main surgical procedure, followed by pneumonectomy. A total of 5 patients developed postoperative complications without any mortality. In conclusion, bronchogenic carcinoma is rapidly increasing without a predilection for sex in the Iraqi population. Advanced preoperative staging and investigation tools are required to determine the rate of resectability., Competing Interests: The authors declare that they have no competing interests., (Copyright: © Marie et al.)

Based on the literature, there are only three reports available to date on synchronous Kaposi sarcoma (KS) and renal cell carcinoma (RCC), at least to the best of our knowledge. The present study reports a rare case of synchronous classic KS and clear cell RCC. A 69-year-old male presented with painful, purplish nodular lesions on the dorsal aspect of his hands and feet. He had no chronic medical illnesses or prior surgical interventions. An excisional biopsy of one of the lesions revealed a nodular dermal lesion with numerous vascular channels and interlacing spindle cells. A 2.5 cm-enhancing mass was found in a contrast-enhanced computed tomography scan of the abdomen, suggesting RCC or metastasis. A partial nephrectomy was performed, and the histopathological findings were consistent with clear cell RCC. The patient responded well to paclitaxel and topical imiquimod (5%), and the skin lesions disappeared. Both KS and RCC are vascular tumors, and their pathogenesis is commonly affected by an angiogenic factor known as vascular endothelial growth factor (VEGF). A complete response of KS was observed after sorafenib, an inhibitor of VEGF receptors, was administered for the treatment of metastatic renal cancer. This reinforces the fact that there is a common therapeutic and pathogenetic pathway between these two neoplasms. Synchronous KS and clear cell RCC are rare findings. Their simultaneous appearance may be triggered by the common enhancing angiogenic factor, VEGF., Competing Interests: The authors declare that they have no competing interests., (Copyright: © Bapir et al.)

Introduction: To date, no systematic review or meta-analysis study has been conducted regarding the use of video-assisted thoracoscopic surgery (VATS) in the removal of intrathoracic foreign bodies (FB). This systematic review aims to evaluate the feasibility of VATS in the removal of intrathoracic FBs., Methods: PubMed/MEDLINE, CINAHL, Web of Science, EMBASE, and Cochrane Library databases were systematically searched to identify reports published up to April 1, 2022., Results: The initial systematic search revealed a total of 208 papers, of which only 54 studies reporting 71 cases were included in this systematic review. Among the patients, 46 (64.8%) were male, 22 (31%) were female, and 3 (4.2%) were unknown. The mean age was 34.5 ± 24.3 years (1 day to 98 years). The patients were of 3 etiologic groups: iatrogenic (31, 43.7%), traumatic (28, 39.4%), and accidental (9, 12.7%). Most of the patients were emergency cases (27, 38%). The most frequently used imaging modalities to diagnose these foreign bodies were X-ray (46, 64.8%), followed by computed tomography (44, 62%), and ultrasonography (16, 22.5%). About 43% of all the foreign bodies were therapeutic equipment. The pleural cavity had the highest involvement (36.8%), followed by the lung parenchyma (14.6%) and thoracic cavity (13.2%). Regardless of the number of access ports, all the patients had a good clinical outcome., Conclusion: VATS is a safe and effective method for the removal of intrathoracic FBs from various thoracic sites that are associated with a good clinical outcome - in both elective and emergency cases., Competing Interests: Conflict of interestThe authors have no conflicts of interest to disclose., (© Indian Association of Cardiovascular-Thoracic Surgeons 2022, Springer Nature or its licensor (e.g. a society or other partner) holds exclusive rights to this article under a publishing agreement with the author(s) or other rightsholder(s); author self-archiving of the accepted manuscript version of this article is solely governed by the terms of such publishing agreement and applicable law.)

Homocystinuria is a rare genetic disease with autosomal recessive pattern. It is reported to be highest in Arabian descend and could cause thrombosis, but mainly peripherally. Cardiac amorphous tumor has been recognized in the past 20 years and it is also a very rare cause primary benign tumor of the heart. Most of the cases reported to be associated with end-stage renal disease. Homocystinuria associated with Cardiac Amorphous tumor is extremely rare. Up to our knowledge, there has been only one other case has been reported. Our patient is a 14-year-old female known case of homocystinuria presented with dyspnea and leg edema. On workup was found to have a mass in the right atrium extending to superior vena cava and inferior cava. Surgery undertaken on cardiopulmonary bypass partial resection of the mass was done and result came back as cardiac amorphous tumor. We assume the cause of this sinister complication of her primary illness is calcification of thrombus as stated in literature. And also recommend further studies regarding issue on hand., (© 2022 The Authors.)

The Bentall procedure is a surgical technique used in the management of aortic root abnormalities with ascending aorta and aortic valve issues. The present study aimed to evaluate the outcomes of 18 patients treated with the Bentall procedure in a single center. The present study was a single-center retrospective case series conducted over a period of 3 years. The patients had either acute ascending dissection and/or dilated ascending aorta with aortic valve dysfunction. The Bentall procedure was performed via standard median sternotomy. St. Jude Medical composite grafts with a valve were applied in all cases. A total number of 18 patients with either acute ascending dissection and/or dilated ascending aorta with aortic valve dysfunction were included in the study. The age of the participants ranged from 27-60 years. The ratio of males to females was 16:2 (males, 88.8%). The symptoms developed 3-4 days prior to hospital admission. Chest pain was the most common presenting symptom (n=10, 55.5%). Hypertension was the most common risk factor (n=12, 66.6%). In total, 14 cases underwent emergency surgery (77.7%). The emergency surgery was performed in 9 patients within 24 h of arrival owing to the association of aortic root dissection with tamponade. For the other cases, the surgery was performed within 2 and 7 days (n=5, 27.7% and n=4, 22.2%) respectively. Early post-operative complications occurred in 5 patients (27.7%). On the whole, as demonstrated herein, the modifications of the Bentall procedure have a notable impact on decreasing the overall mortality rates. Raising the awareness of clinicians and the general population as regards aortic dissection may aid in the early referral of patients to specialized centers and may thus decrease the overall mortality rate., Competing Interests: The authors declare that they have no competing interests., (Copyright: © Al-Mudhaffar et al.)

The deep ocean is the largest ecosystem on the planet, constituting greater than 90% of all habitable space. Over three-quarters of countries globally have deep ocean within their Exclusive Economic Zones. While maintaining deep-ocean function is key to ensuring planetary health, deficiencies in knowledge and governance, as well as inequitable global capacity, challenge our ability to safeguard the resilience of this vast realm, leaving the fate of the deep ocean in the hands of a few. Historically, deep-ocean scientific exploration and research have been the purview of a limited number of nations, resulting in most of humankind not knowing the deep ocean within their national jurisdiction or beyond. In this article, we highlight the inequities and need for increased deep-ocean knowledge generation, and discuss experiences in piloting an innovative project 'My Deep Sea, My Backyard' toward this goal. Recognizing that many deep-ocean endeavours take place in countries without deep-ocean access, this project aimed to reduce dependency on external expertise and promote local efforts in two small island developing states, Trinidad and Tobago and Kiribati, to explore their deep-sea backyards using comparatively low-cost technology while building lasting in-country capacity. We share lessons learned so future efforts can bring us closer to achieving this goal. This article is part of the theme issue 'Nurturing resilient marine ecosystems'.

Background: As the therapeutic regimens against the COVID-19 remain scarce, the microRNAs (miRNAs) can be exploited to generate efficient therapeutic targets. The miRNAs have been found to play pivotal roles in the several regulatory functions influencing the prognosis of viral infection. The miRNAs have a prospective role in the up and down regulation of the ACE2 receptors. This review examines the clinical applications, as well as the possible threats associated with the use of miRNAs to combat the deleterious consequences of SARS-CoV-2 infection., Methodology: This article was compiled to evaluate how the miRNAs are involved in the SARS-CoV-2 pathogenesis and infection, and their potential functions which could help in the development of therapeutic targets against the COVID-19. The sources of the collected information include the several journals, databases and scientific search engines such as the Google scholar, Pubmed, Science direct, official website of WHO, among the other sites. The investigations on the online platform were conducted using the keywords miRNA biogenesis, miRNA and ACE2 interaction, therapeutic role of miRNAs against SARS-CoV-2 and miRNA therapy side effects., Results: This review has highlighted that the miRNAs can be exploited to generate potential therapeutic targets against the COVID-19. Changes in the miRNA levels following viral replication are an essential component of the host response to infection. The collection and modification of miRNA modulates may help to minimize the deleterious consequences of SARS-CoV-2 infection, such as by controlling or inhibiting the generation of cytokines and chemokines. The degradation of viral RNA by the cellular miRNAs, along with the reduced expression of ACE2 receptors, can substantially reduce the viral load. Specific miRNAs have been found to have an antiviral influence, allowing the immune system to combat the infection or forcing the virus into a latency stage., Conclusion: This review summarizes several studies revealing the involvement of miRNAs in diverse and complex processes during the infection process of SARS-CoV-2. The miRNAs can substantially reduce the viral load by degradation of viral RNA and reduced expression of ACE2 receptors, besides mitigating the deleterious consequences of the exaggerated secretion of cytokines. Extensive investigations need to be done by the scientific community to utilize the miRNA based strategies for the development of effective therapeutic targets against the COVID-19., Competing Interests: Declaration of competing interest All authors report no conflicts of interest relevant to this article., (Copyright © 2022 The Author(s).

Introduction: Carcinoma of breast is a heterogeneous disease. Using their light microscopic appearance, the invasive forms are usually divided into three main types: infiltrating lobular carcinomas, infiltrating ductal carcinomas, and other infiltrating carcinomas. This paper aims to discuss and report a case of bilateral invasive ductal carcinoma of the breast., Case Report: A 48-year-old female presented with bilateral breast masses of 5-month duration. On examination. she had bilateral palpable breast masses, which were hard, mobile, and irregular. On the right side, there was skin tethering and palpable axillary lymph nodes. Ultrasound examination showed a heterogeneous, irregular, ill-defined, mass-like lesion, seen in the upper outer quadrant of the right breast along with a hypoechoic. irregular mass 12*13mm in the upper outer quadrant of the left breast. FNA showed bilateral invasive ductal carcinoma. Right axillary lymph nodes were positive for adenocarcinoma. She received 4 sessions of NACT which was followed by right-side mastectomy with axillary lymph node dissection and left-side mastectomy with sentinel lymph node biopsy., Discussion: Bilateral breast carcinomas are very rare. They form 2-5% of all breast malignancies. About 2-11% of breast cancer patients develop cancer in the opposite breast in their lifetime with an incidence rate varying from 4 to 8 per 1000 people per year., Conclusion: Bilateral carcinoma of the breast is very rare. Microscopically, the findings usually reveal infiltrative ductal carcinoma. The treatment of choice is bilateral modified radical mastectomy., (© 2022 The Authors.)

Introduction; Pulmonary fibrosis is a frequently reported COVID-19 sequela in which the exact prevalence and risk factors are yet to be established. This meta-analysis aims to investigate the prevalence of post-COVID-19 pulmonary fibrosis (PCPF) and the potential risk factors. Methods; CINAHL, PubMed/MEDLINE, Cochrane Library, Web of Science, and EMBASE databases were searched to identify English language studies published up to December 3, 2021. Results; The systematic search initially revealed a total of 618 articles - of which only 13 studies reporting 2018 patients were included in this study. Among the patients, 1047 (51.9%) were male and 971 (48.1%) were female. The mean age was 54.5 years (15-94). The prevalence of PCPF was 44.9%. The mean age was 59 years in fibrotic patients and 48.5 years in non-fibrotic patients. Chronic obstructive pulmonary disease was the only comorbidity associated with PCPF. Fibrotic patients more commonly suffered from persistent symptoms of dyspnea, cough, chest pain, fatigue, and myalgia (p-value < 0.05). Factors related to COVID-19 severity that were associated with PCPF development included computed tomography score of ≥18, ICU admission, invasive/non-invasive mechanical ventilation, longer hospitalization period, and steroid, antibiotic and immunoglobulin treatments (p-value < 0.05). Parenchymal bands (284/341), ground-glass opacities (552/753), interlobular septal thickening (220/381), and consolidation (197/319) were the most common lung abnormalities found in fibrotic patients. Conclusion, About 44.9% of COVID-19 survivors appear to have developed pulmonary fibrosis. Factors related to COVID-19 severity were significantly associated with PCPF development., (© 2022 The Authors.)

Introduction: Coronavirus disease 2019 (COVID-19) has evolved as a result of severe acute respiratory syndrome coronavirus 2 (SARS-CoV2). With the rise of cases worldwide, plenty of potential COVID-19 complications have emerged, including increased susceptibility to subsequent bacterial and fungal infections. This study aims to report four cases of COVID-19 associated with pulmonary mucormycosis., Method: This is a multi-center case series study. Diagnosis of COVID-19 was confirmed by reverse transcriptase-polymerase chain reaction., Result: A total of 4 patients infected with SARS-CoV2 were involved in this study. The majority of the cases were female, aged >42 years old. All patients developed severe symptoms. All of the patients had received steroids, half of them had co-morbidities. The most common computerized tomography (CT) scan findings were pulmonary cavitation and empyema. All of the cases were treated with a combination of surgery and antifungal treatment., Conclusion: As the number of COVID-19 cases rises, enhanced surveillance for co-infections with unusual pathogens should be continued. Clinicians should raise awareness of these deadly infections, which can further aggravate severe COVID-19., Competing Interests: There is no conflict to be declared., (© 2022 The Authors.)

Introduction: Despite numerous studies regarding neurological manifestations and complications of COVID-19, only a few cases of neurological consequences following complete recovery from SARS-CoV-2 infection have been described., Objectives: The current study aims to present a quantitative meta-analysis of published studies regarding the post-infectious neurological complications of COVID-19., Data Sources: The Web of Science, PubMed, MEDLINE on OVID, and Google scholar were searched for English-language researches published after January 1, 2020., Result: The review of the literature revealed 60 cases - of which 40 (66.7%) cases were male, and 18 (30%) were female. The average age was 44.95 years. Overall, 17 (28.3%) patients had comorbid conditions. Twenty-four (40%) patients were hospitalized during an active COVID-19 infection. The average interval from the COVID-19 infection to the onset of neurological sequelae was 33.2 days. Guillain-Barre syndrome was the most commonly reported neurological condition (15, 25%)., Conclusion: Despite recovery from acute infection, the pandemic highlights the significance of ongoing, comprehensive follow-up of all COVID-19 patients - even those initially were believed to be asymptomatic., (© 2022 The Authors.)

Introduction: Thin-section chest computed tomography is an important diagnostic test and utilized to determine the severity of lung involvement in COVID-19 pneumonia. The goal of this study is to examine the relationship between CT severity and the oxygen saturation level of individuals with COVID-19., Method: This is a single-center retrospective study of COVID-19 patients that were admitted at a COVID-19 hospital. Patients confirming COVID-19 with PCR testing, patients undergoing lung CT-scan and measures of capillary oxygen saturation using pulse oximetry at the time of admission were all included., Result: The total number of the cases were 105. The age was classified into four age groups, with the majority of them falling into the fourth to sixth decade of life (42, 40%). Diabetes was the most common comorbidity disease (29, 27.6%). Pulse oximetry showed hypoxemia in 87 (82.9%) cases. The most common CT finding was ground glass opacities (GGO) (45, 42.9%). The data showed a significant positive correlation between oxygen saturation and CT severity in patients infected with covid-19., Conclusion: These findings support the importance of using pulse oximetry to monitor COVID-19 patients in order to evaluate or even estimate their clinical situations., Competing Interests: There is no conflict to be declared.l, (© 2022 The Authors.)

Introduction: The osteoclast-like giant cell is a benign tumor that presents as either an isolated benign tumor or one with a carcinomatous component. This study aims to report a rare case of osteoclast-like giant cell tumor (GCT) of the parotid gland., Case Report: A 67-year-old female presented with a painless left pre-auricular swelling of 2-month duration which increased in size gradually over that period. On examination, there was a firm, mobile mass with well-defined borders in the left parotid gland. Fine needle aspiration cytology showed a giant cell-rich lesion that was highly cellular and contained a large number of osteoclast-like multinucleated giant cells, with clusters of spindle and epithelioid cells. Total parotidectomy was performed. After the operation, the patient was sent for radiotherapy., Discussion: The histogenesis and exact nature of this tumor are unknown although numerous ideas have been put forward. The most common clinical manifestation is a painless slow-growing tumor in the parotid area. Primary osteoclast-like GCT of the salivary gland might show concomitant benign or malignant neoplasms. There is also a "pure form" of the tumor that has no accompanying neoplasm., Conclusion: GCT of the parotid gland is a rare tumor. The histogenesis and nature of parotid gland GCT are not completely understood. The treatment of choice is total excision followed by radiotherapy., Competing Interests: None to be declared., (© 2022 The Authors.)

Introduction: Subcutaneous emphysema caused by a surgical operation is known as surgical emphysema, and if the cause is unknown, it is known as spontaneous subcutaneous emphysema. The current study aims to report a rare case of recurrent spontaneous SE of unknown origin., Case Report: A 27-year-old male patient presented with swelling of the chest, neck, and face that had started 20 days prior. There was crepitation on palpation. Pulmonary function tests were normal. Laryngoscopy showed a normal larynx. Bronchoscopy showed a normal bronchial tree except for some redness in the trachea and left main bronchus. Computed tomography of the chest with contrast showed subcutaneous emphysema in the anterior chest and lower neck.The patient reported a similar condition 3 years prior resulting in swelling of the upper left chest with an associated pneumothorax that was treated with tube thoracostomy. Workup including VATS was done to find the underlying cause but no cause was found., Discussion: The pathogenesis is the same as in the most cases. Air that is driven into the interstitial tissues around the pulmonary vasculature gradually moves back toward the lung's hilum, resulting in pneumomediastinum. The air gradually spreads to the soft tissues of the neck, face, chest, and limbs, resulting in widespread subcutaneous emphysema., Conclusion: Spontaneous subcutaneous emphysema without known origin is a rare condition that may resolve by conservative treatment., Competing Interests: None to be declared., (© 2022 The Authors.)

Introduction: Pericardial effusion (PE) related to COVID-19 has rarely been observed, with most reported cases being non-hemorrhagic. This study aims to present a rare case of post-COVID-19 hemorrhagic PE., Case Report: A 44-year-old male presented with shortness of breath upon exertion, palpitation, and left-sided chest tightness. He was a recently recovered from COVID-19. He was conscious, oriented, tachypneic, and tachycardic. Chest examination revealed a mixture of fine and coarse crackles along with muffled heart sounds. He had elevated D-dimer, C-reactive protein, prothrombin time, and aPTT. Computed tomography pulmonary angiogram showed acute pulmonary thromboembolism involving the posterior segmental lobar branch of the left lower lobe with concomitant pulmonary infarction. Echocardiography showed severe PE without diastolic collapse. Pericardial drainage was performed and by the 2nd day, there was no more effusion. On the 7th day, the patient developed severe complications which led to cardiac arrest., Discussion: PE is a collection of fluid in the pericardium. It has been rarely observed in relation to COVID-19, both during and after the viral infection. If PE is suspected, Echocardiography can be used to confirm its diagnosis. There is no standard management for these cases and only non-hemorrhagic patients with mild to moderate effusion can be treated using conservative measures., Conclusion: Hemorrhagic PE can be a rare but possible post-COVID-19 sequel, and echocardiography can be used to confirm its diagnosis. Drainage is necessary to resolve the effusion., Competing Interests: There is no conflict to be declared., (© 2022 The Authors.)

Introduction: Primary non-Hodgkin's breast lymphoma is a very rare entity. The present study aims to report a case of primary diffuse B-cell non-Hodgkin's breast lymphoma., Case Presentation: A 55-year-old female presented with a right breast mass for a duration of 4 months. There was no history of cancer in her family. She has had umbilical hernial repair two years before this presentation. Examination revealed the presence of a suspicious mass in the right breast and multiple axillary lymph nodes. Ultrasound showed a rounded vascular mass (46*40mm) and pathological axillary lymph nodes, U5. Mammography showed a round, dense mass with an indistinct posterior margin and a few round axillary lymph nodes, M4. A Core needle biopsy was done which showed an invasive mammary carcinoma; the result of the FNA of the axillary lymph nodes was benign lymphoid tissue. Histopathological examination confirmed the presence of a tumor, sized 6.4cm, non-Hodgkin's lymphoma. Modified radical mastectomy was performed. The histopathological examination confirmed non-Hodgkin's lymphoma., Clinical Discussion: There are two main groups of primary breast lymphoma. The bilateral diffuse-type affects the younger puerperal women associated with pregnancy or recent childbirth that may involve the CNS, ovaries, and gastrointestinal tract without lymph node involvement. The second type, the unilateral type, which appears in elderly women without extra mammary involvement., Conclusion: Primary breast non-Hodgkin's lymphoma is a rare disease. It mimics breast cancer, and hence, may lead to misdiagnosis. The common modalities of treatment include chemotherapy, radiotherapy, and surgery., Competing Interests: There is no conflict to be declared., (© 2022 The Authors.)

Introduction: Accessory breast (AB) is extra and ectopic breast tissue. Fibroadenoma (FA) in AB is a rare finding. This study aims to present a case of FA in axillary AB mimicking carcinoma of unknown primary (CUP)., Case Report: A 38-year-old female presented with a mass in her right axilla. She had a mass in her right breast for 5 years. She previously had a left breast lumpectomy for a benign condition. The lump in her axilla was palpable and hard. Ultrasound showed an oval lymph node in the level I axilla (12*6mm) with blurred and unclear fatty hilum, suspicious for malignancy. Magnetic resonance imaging revealed an oval lesion (12*7mm) in the level I axilla with no fatty hilum and with heterogeneous enhancements, suggesting abnormal nodes. Fine needle aspiration of the axillary mass suspected CUP. But core biopsy resembled FA. Both masses in the right axilla and breast were surgically excised. Histopathology confirmed FA in both masses., Discussion: Although pathologies in AB are uncommon, it is still susceptible to the same malignant and benign transformations that are found in normal breasts. The axilla is the most frequent location for FA in AB and often affects young women. Imaging techniques can be inconclusive and only histopathology can conclude a definitive diagnosis., Conclusion: FA in axillary AB is a rare condition that causes a diagnostic dilemma as it can be mistaken for other benign or malignant pathologies., Competing Interests: None to be declared., (© 2021 The Authors.)

Introduction: Paget's disease of the breast is a rare cutaneous eczema-like condition that occurs in the nipple-areolar complex of the breast. The current study aims to report a rare case of Paget's disease of the breast associated with invasive ductal carcinoma in a male breast., Case Report: A 54-year-old male presented with ulceration of the left nipple-areolar complex that has been progressing over the last 6 months. On examination; there was a palpable axillary lymph node. On ultrasound, a small hypoechoic heterogenous mass was seen beneath the areola (8*4 mm) with surrounding vascularity, and a few axillary lymph nodes with normal morphology and cortical thickness. The mammography revealed some points of calcification arranged in clusters. The patient underwent left side mastectomy and sentinel lymph node biopsy. The result of histopathological examination showed left side unifocal invasive ductal carcinoma., Discussion: There are two main theories that explain the histogenesis of Paget's disease of the breast with and without underlying malignancy: epidermotropic theory, which suggests an epidermal infiltration of the nipple with Paget cells, and transformative theory, which proposes a malignant transformation of normal glandular cells of the epidermis., Conclusion: The clinical presentation of Paget's disease of the breast is characteristic and should always warn the surgeon of the possibility of underlying malignancy., (© 2021 The Authors.)

Introduction and Importance: For many years, thoracotomy has been considered as the standard approach for thoracic injuries. The aim of the current paper is to report a successful use of video assisted thoracoscopic surgery (VATS) as the first line approach for the removal of a bullet retained deep in the lung parenchymal tissue., Case Presentation: A 46-year-old male presented with a vague pain in the chest at the site of a penetrating bullet injury 26 years prior. Chest and native chest Computed Tomography scan (CT scan) showed a 22 mm foreign body inside the substance of the left lower lobe in the anterior segment. Decision was made to remove the foreign body using VATS. The surgery was performed through an uni-port. The left lower lobe was explored and the foreign body was found within the anterior segment. It was removed and the defect was sutured using Vicryl 2/0., Clinical Discussion: Although VATS has been established to be an accurate evaluating technique for direct evaluation of the chest wall, lung parenchyma, mediastinum and diaphragm, along with its effectiveness in successfully treating a variety of conditions, its use in thoracic trauma is still not well defined., Conclusion: This report supports the use of VATS as an effective and minimally invasive approach in the removal of foreign bodies in lung parenchyma., Competing Interests: None to be declared., (© 2021 The Authors.)

Introduction: Subcutaneous emphysema is an extremely rare complication after lobectomy. The current study aims to report a case of lung cancer developing extensive subcutaneous emphysema after lobectomy., Case Presentation: A 73-year-old man presented with dyspnea and cough for one month duration associated with wheeze and sputum. He was a chronic heavy smoker (100 pack/year). Work up revealed squamous cell carcinoma. Although he had poor pulmonary function tests, he underwent left upper lobectomy. On the fifth postoperative day, he was discharged from the hospital as there was no air leak and the lung remained expanded 15 hours after clamping of the thoracostomy tube. Two days later, the patient developed generalized subcutaneous emphysema. The patient was re-admitted to the hospital and a thoracostomy tube was inserted. The lung expanded upon insertion while the subcutaneous emphysema remained the same and even slightly increased over night. A 3 cm incision was made at the left infra-clavicular area and a negative pressure applied to it. The subcutaneous emphysema completely subsided a few hours after this intervention., Discussion: Because of the benign course, the majority of cases of subcutaneous emphysema (mild to moderate) only need nonoperative management alongside treatment of the predisposing factors. These patients may need nothing other than bed rest, good analgesia, supplemental oxygen, and reassurance., Conclusion: Subcutaneous emphysema after lobectomy prolongs hospital stay. It mainly occurs in cases with poor pulmonary function tests, steroid use, and those with extensive adhesion., Competing Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© 2021 The Authors.)

Patients hospitalized with COVID-19 are at risk of developing many neuropsychiatric disorders, due to the effects of the disease on the brain and the psychosocial pressures of having the disease. The aim of the present study was to evaluate the characteristics and outcomes of patients who were hospitalized with a diagnosis of COVID-19, who underwent psychiatric consultations. The medical records of 892 patients hospitalized due to COVID-19 and the 89 among them who requested psychiatric consultations were analyzed retrospectively. After the psychiatric consultations, patients were most frequently diagnosed with delirium (38.2 %), adjustment disorder (27.0 %), depressive disorder (19.1 %) and anxiety disorder (11.2 %). Patients with delirium had longer hospital stays (p < 0.001), were transferred more frequently to intensive care units (p < 0.001), and had higher mortality rates during their hospital stays (p < 0.001), than all other patients. The need for oxygen (p < 0.001) and mechanical ventilation (p < 0.001) was also significantly higher in delirium patients, as well as in patients who received other psychiatric diagnoses. Neuropsychiatric disorders develop in patients receiving inpatient treatments in COVID-19 wards, and these disorders negatively affect the prognosis of COVID-19. Our findings suggest that the presence of neuropsychiatric disorders in in-patients with COVID-19 might be associated with the negative outcomes of the disease., (Copyright © 2021 Elsevier B.V.

Objective: To assess the level of anxiety among doctors during COVID-19 pandemic and the associated risk factors., Methods: This cross-sectional study was conducted from 30th April to 16th May, 2020 in Karachi, Pakistan. The data was collected via an online web-based questionnaire. Questionnaire was used to assess anxiety level using GAD-7 scale among health-care professionals and the risk factors playing role in it., Results: One hundred and fifty-one doctors participated in our study. Out of these 151 participants, 69 (45.7%) had mild, 22 (14.6%) had moderate, and 5 (3.3%) had severe symptoms of anxiety, whereas the remaining 55 (36.4%) had no anxiety according to GAD-7 scale. The median [interquartile range (IQR)] GAD-7 scale scores are 6.0 [3.00-9.00]. Females showed more severe degrees of measurement of anxiety symptoms than males. Doctors dealing with COVID-19 patients showed higher level of anxiety as compared to the doctors who were not dealing with COVID-19 patients, having a significant difference (U = 9.697, p = 0.008). One hundred and forty-one (93.4%) participants were concerned about being exposed to COVID-19 at work and 112 (74.2 %) thought they have inadequate protective equipment for safety., Conclusions: During COVID-19 pandemic, doctors exhibited different grades of anxiety. In order for healthcare workers to perform to the best of their capability, certain guidelines and interventions are needed., Competing Interests: Conflicts of Interest: None., (Copyright: © Pakistan Journal of Medical Sciences.)

Objectives: To measure stigma among doctors in one of the major specialized hospitals in Saudi Arabia., Methods: This cross-sectional study was conducted at King Abdullah Medical City, Jeddah, Saudi Arabia between October and November 2018. Eighty physicians were recruited in this study. The participants administered the sociodemographic questionnaire as well as the Mental Illness Clinicians' Attitude 4th version (MICA 4)., Results: The overall MICA score ranged between 31 and 61 with a mean±SD of 45.75±7.54. The highest reported score was among outpatient physicians (51.33±6.66), while the lowest score was among consultants/assistant consultants (43.17±7.82)., Conclusion: The results of this study showed a relatively high MICA-4 score that could indicate a high stigmatizing attitude among physicians toward patients with mental illnesses compared with the other MICA-4 studies. Thus, training workshops could improve the attitudes in the short-term.

Background: The Duffy glycoprotein acts as the entry point for merozoites of Plasmodium vivax in the invasion of red blood cells. The host-parasite relationship has revealed new perspectives regarding the association between Duffy polymorphisms that can impact both the parasite density of this Plasmodium and the symptoms of this type of malaria. This study investigates the impact of Duffy polymorphisms on parasite density in patients infected with P. vivax in the Brazilian Amazon region., Methods: Genotypes and Duffy polymorphism allele frequencies were compared in 287 patients with malaria, presenting low, medium and high density of P. vivax. The diagnosis of malaria was performed using a specialized team with a standardized clinical-laboratory method, while the Duffy genotyping was performed through the Bead Chip BioArray system. Both teams are reference services in Brazil., Results: The FY*01 and FY*02 alleles were found in all three parasite density classes: low, medium and high, but when these alleles form genotypes with FY*02N.01 and FY*02W.01 alleles, they are found only in patients with low parasite density and low symptomatology. Another interesting finding found in this study is the presence of the genotype FY*02N.01/FY*02W.01 in one of the patients, presenting a very low parasite density and malaria considered subclinical, a genotype which had not been previously described in the literature., Conclusion: The presence of FY*02N.01 and FY*02W.01 alleles may have an impact on the reduction of clinical manifestations in malaria, leading to the development of subclinical malaria, making the infected individual an undetected natural reservoir, which may hinder the eradication of malaria in the Amazon.

Pharmaceutical compounds are considered emerging environmental pollutants that have a potential harmful impact on environment and human health. In this study, the biomass of alga (Scenedesmus obliquus) was modified using alkaline solution, and used for the biosorption of tramadol (TRAM) and other pharmaceuticals. The adsorption kinetics and isotherms were investigated. The obtained results reveal high adsorption capacity of tramadol over modified algal biomass (MAB) after 45min with removal percentage of 91%. Pseudo-second order model was well fitted with the experimental data with correlation coefficient (0.999). Biosorption of tramadol on modified algal biomass proceeds with Freundlich isotherm model with correlation coefficient (0.942) that emphasized uptake of TRAM by MAB is driven by chemisorption. FTIR spectra of MAB before and after the adsorption were analyzed; some IR bands were detected with slight shift and low intensity suggesting their involving in adsorption. The tramadol biosorption by MAB is a chemical process as confirmed by Dubinin-Radushkevich. The adsorption of pharmaceutical over MAB is mainly preceded by hydrophilic interactions between amino and carbonyl groups in pharmaceutical molecules and hydroxyl and carbonyl functional groups on surface of biosorbent. It was emphasized by disappearance O-H and C-O from biomass IR spectra after adsorption. In matrix of pharmaceutical, the recorded adsorption capacities for CEFA, PARA, IBU, TRAM and CIP are 68, 58, 42, 42 and 39mg/g over MAB at natural pH and MAB dose of 0.5g/L. Furthermore, oxygen uptake by bacteria was applied for estimate the toxicity of pharmaceutical. The recorded result concluded the efficient reusability of modified algal biomass for biosorption of pharmaceuticals, as well only the adsorption efficiency decreased by 4.5% after three runs. Subsequently, the modified algal biomass is a promising reusable adsorbent for decontamination of wastewater from pharmaceuticals., (Copyright © 2018 Elsevier Inc. All rights reserved.)

The present work represents the biosorption of Cd(II) and Pb(II) from aqueous solution onto the biomass of the blue green alga Anabaena sphaerica as a function of pH, biosorbent dosage, contact time, and initial metal ion concentrations. Freundlich, Langmuir, and Dubinin-Radushkevich (D-R) models were applied to describe the biosorption isotherm of both metals by A. sphaerica biomass. The biosorption isotherms studies indicated that the biosorption of Cd(II) and Pb(II) follows the Langmuir and Freundlish models. The maximum biosorption capacities (qmax ) were 111.1 and 121.95 mg/g, respectively, at the optimum conditions for each metal. From the D-R isotherm model, the mean free energy was calculated to be 11.7 and 14.3 kJ/mol indicating that the biosorption mechanism of Cd(II) and Pb(II) by A. sphaerica was chemisorption. The FTIR analysis for surface function group of algal biomass revealed the existence of amino, carboxyl, hydroxyl, and carbonyl groups, which are responsible for the biosorption of Cd(II) and Pb(II). The results suggested that the biomass of A. sphaerica is an extremely efficient biosorbent for the removal of Cd(II) and Pb(II) from aqueous solutions.

Family and systemic therapists are becoming increasingly interested in evidence-based practice. By implication, clinical supervision practices that support therapists need to keep step with this trend. Supervision practices within Multisystemic Therapy as a more outcome-focussed treatment model that works with families are compared with the supervision of family therapists working a mental health clinic. This paper looks at some of the more prominent supervisory practices in MST and Family Therapy and explores their similarities and differences. The various challenges that are present when working in clients' homes are explored and implications for supervision discussed. Therapists who frequent clients' homes may need a different skill-set and their supervisors in turn require taking a different approach. The clinical supervisor to a therapist working out in the community tends to (be able to) be more proactive. Systemic supervisors to more clinical based family therapist put emphasis on the explorative aspects of the therapeutic encounter including self-reflective practices, whereas MST supervisors' primary focus remains on the clinical outcomes for the clients. The place of self-reflexivity in both approaches to supervision is explored. Case examples drawn from the authors' own supervisory practice will be presented to illustrate the different practices presented.
