Sex-related Variations Respiratory tract Proportions: A survey Based on Quantitative Computed Tomography between Chinese language Human population.
We aim to highlight the importance of timely diagnosis and further management in such clinical scenarios, where permanent vision loss can compromise someone's quality of life.Hepatosplenic T-cell lymphoma is a rare but highly aggressive form of T-cell malignancy. As cases are not routinely seen in practice, the malignancy can be confused with other hematologic conditions that have a similar presentation. Here in, we present the challenges faced in diagnosing a 27-year-old-male who initially presented with asymptomatic pancytopenia and then developed massive splenomegaly over the next three months. After an elaborate workup, including a bone marrow biopsy and extensive serological testing, which all turned out to be negative, he eventually underwent a splenectomy with biopsy results confirming hepatosplenic T-cell lymphoma.March 11, 2020, marked the start of the coronavirus disease 2019 (COVID-19) pandemic. COVID-19, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), was being reported as severe respiratory illness. However, since the recognition of this novel virus, there has been a constant realization that it may present or manifest in a multitude of ways. At first, the typical signs and symptoms were what one would expect from a respiratory virus cough, shortness of breath, and fever. However, as the disease became more prevalent, neurologic symptoms were reported such as headaches, hypogeusia, and hyposmia. This case report aims to add to the growing body of neurologic manifestations by presenting two cases, Bell's palsy and Guillain-Barre Syndrome. Each case involves flaccid paralysis as the primary presentation.Acute testicular infarction requiring emergent surgical intervention is often the result of spermatic cord torsion; infrequently, infarction results from other etiologies. We report a case of epididymo-orchitis complicated by abscess resulting in testicular ischemia, not detected on ultrasonography. A high clinical suspicion of testicular ischemia should be maintained in any presentation of testicular pain and swelling, as recognition could lead to early salvage interventions.Gonadoblastoma is a rare ovarian neoplasm which belongs to "germ cell-sex cord-stromal tumor" category. This tumor is frequently associated with invasive germ cell malignancy. It commonly arises in dysgenetic gonads of young individuals who are phenotypically females but possess 46XY karyotype. It has been rarely reported in females with normal phenotype and genotype. We herein describe a case of 10-year-old female who presented with abdominal pain, abdominal distention and fever. CT scan of the abdomen and pelvis revealed bilateral ovarian masses, ascites and pelvic and para-aortic lymphadenopathy. Serum lactate dehydrogenase levels were also elevated. She underwent left salpingo-oophorectomy, right ovarian biopsy, omentectomy and para-aortic lymphadenopathy. Microscopically, tumor showed in situ and invasive components. In situ component was arranged in nests and lobules formed by immature sertoli cells forming acini and encircling large polygonal primitive germ cells. Immature sertoli cells were positive for immunohitochemical (IHC) stains cytokeratin AE1/AE3, inhibin and calretinin, while germ cells were positive for SALL4, Oct 3/4, placental alkaline phosphatase (PLAP) and CD117. Invasive component was arranged in sheets of large-sized, polygonal-shaped primitive germ cells which were also positive for SALL4, Oct 3/4, PLAP and CD117 IHC stains. Hence, the diagnosis of "gonadoblastoma with dysgerminoma" was made. The tumor was limited to both ovaries. Cytogenetic analysis of peripheral blood revealed normal female 46XX karyotype. The patient received two cycles of adjuvant chemotherapy and was then lost to follow-up. We conclude that gonadoblastoma, although rare, should be considered as a differential diagnosis in ovarian tumors of young females. Invasive germ cell component should always be carefully searched for as it guides about treatment and predicts prognosis.The spread of COVID-19 has been exponential throughout the globe. Though only a small percentage of infected individuals reach the critical stage of the disease, i.e., acute respiratory distress syndrome (ARDS), this percentage represents a significant number of patients that can overwhelm the healthcare system. Patients presenting with ARDS need mechanical ventilation, as their lungs are unable to oxygenate blood on their own due to fluid accumulation. One way to manage this excess pressure of fluid build-up around the lung tissues is to relieve the dorsal alveoli by prompting the patient to lie face down on the stomach; this is called awake proning. It is a procedure that is directed towards the recruitment of lung parenchyma when infected with pneumonia or when the condition has worsened into ARDS. This helps in relieving the pressure from the dorsal lung surface that has markedly higher perfusion than the ventral surface. Awake proning delays the use of mechanical ventilation and facilitates the patients with severe ARDS or severe pneumonia in maintaining the supply of oxygen to the body tissues. Since medical institutes are overburdened and limited ventilators are available, awake proning can reduce not only the burden on hospitals but also decrease the need for ventilators.The erector spinae plane (ESP) block is a regional block that has become more commonly utilized in the setting of acute pain and post-operative analgesia. This block has been successfully utilized for pain management after a variety of surgical procedures for immediate post-operative pain management. selleck chemical This block is now gaining more utilization in the chronic pain setting for neuropathic pain conditions. We describe the use of this block at our pain clinic for the treatment of two patients with refractory neuropathic pain after thoracotomy as well as video-assisted thoracic surgery (VATS). Our cases further demonstrate the utility of this block for long-term pain control of neuropathic pain conditions, especially post-thoracotomy pain.Background There is growing evidence of a strong association between obstructive sleep apnea (OSA) and cardiovascular co-morbidities including atrial fibrillation (AF). We wanted to assess the usefulness of the overnight cardiac monitoring to screen for AF during the sleep study in patients newly diagnosed with OSA, in order to establish the usefulness of overnight active screening for subclinical AF during the sleep study in these patients. Methods A retrospective study in patients with new diagnosis of OSA carried out between January 2014 and December 2019 in the sleep clinic at King Abdulaziz University Hospital, Jeddah, Saudi Arabia. All patients newly diagnosed with OSA (apnea-hypopnea index >5) were selected to undergo a clinical questionnaire regarding symptoms, co-morbidities and risk factors. Subjects with history of cardiac arrhythmias or having anti-arrhythmic treatment were excluded. Eligible patients underwent an overnight rhythm monitoring to screen for AF or any rhythm disturbance. Results We included 250 respective patients with OSA, 54% were males and 82% aged more than 35 years.
