Cerebral brain injuries (CBIs) account for up to 20% of all injuries in boxing. Approximately 97% of sports-related brain injuries are mild, their neurological symptoms are unexpressed, and young, strong, highly motivated athletes tend to dismiss the severity of their injuries. This may lead to an underestimation of the severity and extent of brain injuries. Changes in computed tomography (CT) and magnetic resonance imaging (MRI) in mild traumatic brain injury are absent in the early stages, making diagnosis difficult. Frequent repetitive traumatic brain injuries, including mild brain injuries, can result in functional and structural brain lesions that affect athletes’ performance and, in the long term, significantly impair their quality of life. Also, the consequences of cerebral brain injuries, including mild brain injury, can be affected by the individual condition of the Circle of Willis.
his patient (male, 59 years old) underwent cardiac re-transplantation for chronic rejection. Prior to re-transplantation, the patient was in NYHA class IV, with a clear chest x ray. On 14th postoperative day, he presented hemoptysis. On chest x-ray, a left lower lobe opacity was seen. Therefore, a chest CT scan was done and it showed a round mass within a pulmonary cavity surrounded by airspace in proximity of the pulmonary artery.
Introduction: COVID-19 is an infectious disease caused by the severe acute respiratory syndrome coronavirus 2 and it was first reported in China. The aim of this study was to compare clinical features, chest CT findings and laboratory examinations of suspected COVID-19 inpatients according to RT-PCR analysis.
Methods: Demographics, comorbidites, symptoms and signs, laboratory results and chest CT findings were compared between positive and negative groups. The study included 292 patients (134 females, 158 males) suspected of COVID-19. All statistical calculations were performed with SPSS 23.0.
Results: 158 (54.1%) of the cases were male and 134 (45.9%) were female. Their ages ranged from 17 to 95 years, with an average of 50.46 ± 20.87. A symptom or sign was detected in 86.3% of all patients. The chest CT images of 278 patients were analyzed. Chest CT was negative in 59.2% of patients with positive RT-PCR and 43.9% of patients with negative RT-PCR results. Chest CT findings were atypical or indeterminate in 22.4% of patients with positive RT-PCR results and 20% of patients with negative RT-PCR analysis. ALP, bilirubine, CRP, eosinophil count, glucose, CK-MB mass and lactate were significantly lower in patients with positive RT-PCR test. LDH, lipase, MCV, monocyte, neutrophil count, NLR, platelet, pO2, pro-BNP, procalcitonin, INR, prothrombin time, sodium, troponin T, urea, WBC were significantly lower in patients with positive RT-PCR test results.
Conclusion: The diagnosis of COVID-19 is based on history of patient, typical symptoms or clinical findings. Chest CT, RT-PCR and laboratory abnormalities make the diagnosis of disease stronger.

Introduction: This study aims at evaluating selected linear anthropometrics of three Nigerian ethnic groups to provide baseline data for the creation of 3D Negroid anatomic models.Methods: The research design was a cross-sectional design. The sampling technique was multistage proportionate random sampling. The places of study were Imo, Oyo, and Kano States of Nigeria. The study lasted for one (1) year. Random selection of 1500 adult males from three major tribes (500 Igbo, 500 Yoruba, and 500 Hausa between the ages of 18 and 40 years). Tukey’s Post Hoc test of multiple comparisons was carried out to determine the specific ethnic groups that differ in specific anthropometric parameters.Results: The differences in standing height, arm length, and thigh length across the Hausa, Igbo, and Yoruba ethnic groups are statistically significant (p < 0.05). Conclusion: The study concluded that the Igbo and Yoruba groups had higher standing heights compared to the Hausa group. Arm length was longer in the Igbo and Yoruba groups compared to the Hausa group. However, thigh length was greater in the Hausa group compared to both the Igbo and Yoruba groups, while the Hausa group had longer thigh lengths than both the Igbo and Yoruba groups. The Igbo group displayed the largest arm span, whereas the Hausa group had the widest shoulder breadth. However, the Hausa group had a lower bi-iliac breadth in comparison to the other two ethnic groups.
Meigs syndrome is an uncommon presentation, where a benign ovarian neoplasia presents along with ascites and pleural effusion. About 1% of ovarian neoplasia can present as Meigs syndrome. Patients with Meigs’ syndrome and elevated serum CA-125 are not frequently reported. We report a case of a 50-year-old women who presented with shortness of breath, cough, weight loss of one and half month duration. Chest radiograph of the patient with clinical examination of patient confirms pleural effusion as cause of progressive shortness of breath. The presence of a pelvic mass and elevated serum CA-125, which raised the possibility of malignancy. After complete resection of tumor, the pathologic reports confirmed a benign ovarian neoplasia. We highlight the importance of suspicion, careful general examination, radiological assessment and histological tests to confirm the diagnosis of Meigs’ syndrome.
The authors describe the unusual case of subungual onychomycosis, due to fluconazole and itraconazole resistant Candida albicans after using the hybrid and acrylic lacquers and nail tips. The etiology of these atypical changes was supported by isolation of the fungus from the nail lesions, and its consistent identification by means of morphological and molecular diagnosis. In the presented case, topical treatment with ciclopirox 8% nail lacquer allow to fight the pathogenic fungus but did not restore the natural appearance of the nails.
A 63 year old gentleman presented with ulcer over the lower alveolus for the past 4 months duration. The patient also had pain, loose lower central incisors and occasional bleeding from the ulcer while brushing. On examination an ulceroproliferative growth was seen involving lower alveolus along with adjoining mucosa of the lower lip with mobile central incisors. There was associated bilateral submandibular area lymphadenopathy.
The background of this novel study is how to apply an empirically adjusted Passive House concept in the tropics - beyond its otherwise prevailing global standards. Even though well-insulated houses have been on the planet since people settled down in some of their first dwellings, passive in the 21st century is different. It includes strict rules for airtightness and fitting of windows along with a sophisticated concept for artificial ventilation. Fresh air reachable from outside by filtered ventilation with heat recovery describes the heart of the system - if natural outside air is not preferable, it is convenient just in seasons with thermal comfort.Hence, the purpose and aim of the study presented here is to use a less common and at the same time more cost-saving approach: It might seem that the modern type of passive house entails the same standards that have been developed firmly on its own global market niche. However, this article tries to contribute toward a new development of modern passive homes for low-cost affordable tropical and subtropical houses in their entirety.As a concluding note, the author states that nobody has ever disproven this evolving concept as a combination of airtightness and a new way of forced ventilation without heat- or coolness recovery which is highly applicable for low-cost residential areas in tropical countries. By generating lower temperatures, it can help to surpass the overheating caused by climate change in certain tropical climate zones in higher altitudes and during cooler seasons. The condition is that the occupants are willing to accept a thermal comfort of up to 28 °C and humidity in its 70s and 80s.
This is a work based on the extension of the work of Professor James Clerk Maxwell and Albert Einstein into a new framework of science built on provable mathematical theorem which serves as a basis for unifications of the fundamental forces which all together have become impossible to unify under the current framework of General relativity and Quantum Field theory.It is to be used as a piece for inspiring new innovations, discovering and exploring the terrains of the difficult pathways in physics where our modern physical theories have failed.This work is meant to be adapted and used by various physics professionals who are working on extending the frontiers of physics or providing solutions to problems that cannot be handled by current physics framework. In summary it is an inspirational tool that hopefully will help our professional in physics out there.It interpretations and applications is subject to the personal inspirations the reader who is a professional can derived from the work for his or her personal usage.
