The Paradigm Change to Arrange Tranny Paths along with Systems.
Saddle aortic embolism is a rare life-threatening condition that may present solely with low back pain. The case demonstrated a possible complication of COVID-19 that occurred after the recovery from the acute phase of the disease.Objectives Vitamin D deficiency, which is common worldwide, increases the risks of falls and fractures and can lead to increased morbidity and mortality. However, the clinical utility and relevance of vitamin D activation remain unknown. The aim of the present study was to clarify the clinical usefulness of serum 1,25-dihydroxyvitamin D (1,25D)/25-hydroxyvitamin D (25D) ratio for assessment of the extent of bone metabolism. Methods We retrospectively screened data for 87 patients whose serum 1,25D and 25D levels were measured. Eight patients who were taking vitamin D preparations were excluded, and data for 79 patients (33 males and 46 females) were analyzed. Since menopausal status can be associated with serum vitamin D level, we divided the patients by gender and divided the female patients into two groups at the age of 50 years. Results The median serum 1,25D/25D ratio was significantly lower in males than in females, with the most considerable difference in all males [4.1 (interquartile range 2.3-5.8) × 10-3] versus elderly females (aged ≧50 years) [7.9 (3.3-10.1) × 10-3). Main disorders were endocrine (30.6%), inflammatory (18.5%), and bone-related (16.7%) disorders. The ratios of serum 1,25D/25D had significant negative correlations with femoral dual-energy X-ray absorptiometry % young adult mean (DEXA %YAM) (R=-0.35) and lumbar DEXA %YAM (R=-0.32). Significant correlations were found between the 1,25D/25D ratio and serum levels of inorganic phosphate (iP), parathyroid hormone, and alkaline phosphatase (ALP). The 1,25D/25D ratio had gender-specific characteristics the ratio was significantly correlated with age in males (R=-0.49), while it was significantly correlated with BMI in females (R=0.34). Conclusions The results of this study suggested that vitamin D activity is negatively correlated with bone mineral density, being reduced in aged males but enhanced in obese females.
It has been suggested that post-transoral robotic surgery (post-TORS) radiotherapy (RT) might reduce the dose to organs at risk (OARs) adjacent to the primary tumor bed; however, the evidence supporting this has yet to be sufficient. This study examined the radiation dose reduction to OARs by omitting the primary tumor bed through the use of an Auto-Planning (AP)-based workflow.

Twelve patients were identified who underwent post-TORS RT to the primary tumor bed and the unilateral/bilateral neck lymph nodes. In each patient, two treatment plans were designed a Comprehensive (Comp)-plan treating the original planning target volume (PTV) including both the primary tumor bed andthe lymph nodes, and a Neck-plan treating only the lymph nodes and omitting the primary tumor bed. Both plans were optimized using AP to ensure plan quality consistency.We compared the doses received by 95% of the primary tumor beds and lymph nodes (D95%) and our institutional dose constraints for the OARs between the Comp- and Neck-plose reductions to the oral cavity and supraglottis. Further study of the clinical risks and benefits afforded by this strategy is needed.A man with systemic sclerosis (SS), manifested by characteristic skin lesions, gastro-esophageal reflux disease, and pulmonary fibrosis producing progressive respiratory failure, and a positive antinuclear antibody consistent with reactivity to fibrillarin, developed skin lesions with the clinical and histological characteristics of lupus erythematosus tumidus (LET) 10 years after the diagnosis of SS. His respiratory failure progressed and he expired from sepsis after tracheal intubation and mechanical ventilation two years after developing LET. The association of SS and LET, not described until now, raises questions about its pathogenesis and its prognostic significance.Introduction Validation assesses the acceptability, responsiveness, interpretability, and quality of any questionnaire in any specific population. This is done by correlation matrix evaluation of the proposed test tool with a previously well-validated assessment tool. The study objective is the dual-center assessment of the construct validity of the first health-related quality of life questionnaires for married and unmarried women with polycystic ovary syndrome (PCOS), i.e., PCOSQoL-47 and PCOSQoL-42, respectively. Materials and methods At two centers in Iraq, we enrolled 406 married women and 362 unmarried women with PCOS to test for the construct validity of PCOSQoL-47 and PCOSQoL-42, respectively, from August 2019-August 2020 (after obtaining full results of reliability testing in our previous work). We used the comparable domains from the multiculturally validated questionnaire (World Health Organization Quality of Life [WHOQOL-BREF]) as a comparator to assess the construct validity of the domains of theween the two constructs at (p0.5. The PCOSQoL-42 and PCOSQoL-47 showed high inter-rater reliability levels in measuring the requested construct or concept when we used Cronbach's alpha and inter-item correlation matrix assessment. Conclusion The individualized PCOSQoL-47 and PCOSQoL-42 for married and unmarried women with PCOS, respectively, represent the first reliable and valid HRQoL assessment tools for assessing the health-related quality of life (HRQoL) in those women with PCOS who use Arabic as a first or native language and address the sexual function as a separate domain.Decompressive hemicraniectomy (DCHC) may be indicated in the setting of subarachnoid hemorrhage (SAH) complicated by persistent elevated intracranial pressure (ICP) that is refractory to medical interventions. Outcomes can be variable as indications for surgery can include focal hematomas, infarctions, and regional or diffuse edema. Bilateral DCHC for medically refractory elevated ICP in the setting of SAH is not well described in the literature, and the viability of this option in terms of patient outcomes is unclear. We describe the cases of four patients with medically refractory ICP secondary to diffuse cerebral edema who underwent bilateral DCHC in the setting of SAH. This is a retrospective case review of four patients with aneurysmal SAH who underwent bilateral DCHC for management of diffuse global edema resulting in medically refractory ICP. We describe two patients who made impressive recoveries after bilateral DCHC and two patients who required significant continued care needs despite ICP control in all patients. Bilateral DCHC is a viable option for control of refractory elevated ICP in SAH patients who develop diffuse cerebral edema. Bilateral DCHC in this setting can be considered after exhaustion of other therapeutic options.Acute abdominal pain is a common cause of visits to the emergency department. Acute appendicitis remains the most common indication for abdominal surgical intervention in the pediatric age group. However, several conditions may present with a clinical picture similar to that of acute appendicitis. We report the case of a 7-year-old girl with a history of right lower quadrant abdominal pain of two days in duration. The pain was associated with vomiting and was exacerbated by movement. Abdominal examination revealed a localized tenderness in the right iliac fossa with guarding, giving the impression of acute appendicitis. After a thorough investigation, the patient was diagnosed as having acute omental infarction given the radiological findings seen in the computed tomography scan. The patient was successfully managed conservatively with analgesics and anti-inflammatory drugs. Physicians should keep a high index of suspicion for this condition when encountering a patient presenting with an acute right lower quadrant abdominal pain. Imaging modalities play a pivotal role in making the diagnosis.Granulosa cell tumor (GCT) is a unique form of sex cord tumor that is mostly unilateral and of low-grade malignancy. Most GCT recurrence is with pelvic or peritoneal dissemination. Liver metastasis is rarely reported. This study reports a rare case of GCT with liver metastasis nine years post initial presentation. We also discuss surgical intervention, radiological findings, histology, treatment approaches, and review of similar reported cases.Our understanding of the risk of developing severe coronavirus disease 2019 (COVID-19) infection in the population living with HIV is still evolving. In this report, we discuss the successful management of COVID-19-related acute respiratory distress syndrome (ARDS) in an active case of the human immunodeficiency virus (HIV) infection; the patient had an atypical presentation characterized by very rapid progression in the severity of respiratory symptoms needing invasive mechanical ventilation. The way the case was managed broke with the custom that mechanical ventilation in patients with COVID-19-related ARDS should be deferred as much as possible since the chances of survival are minimal, especially in immunocompromised patients. Although patients with HIV infection are immunocompromised and at risk of secondary infection, young age, lack of comorbidities, and early intubation may result in a good prognosis. ARDS ventilation strategy, good infection control practices, and individualized patient care can help to wean patients off mechanical ventilation. Recent evidence does not support the use of antiretroviral drugs for prophylaxis or treatment of COVID-19 infection.A 32-year-old female with unexplained infertility delivered a healthy male infant at 39 weeks 0 days gestational age; the pregnancy was facilitated by in vitro fertilization. Shortly after delivery, she was found to have a morbidly adherent placenta. Attempted removal resulted in postpartum hemorrhage and ultimately hysterectomy after attempting multiple fertility preserving methods to achieve hemostatic control. Pathology results revealed a diagnosis of a 0.1 cm placenta increta (Grade 2 placental villi invasion), the least common diagnosis within the placenta accreta spectrum (PAS). Likely due to the small point of trophoblastic invasion, the diagnosis and outcome were not foreseen. This case highlights the need for additional data collection and development of standardized guidelines for the diagnosis and management of PAS, given a patient's risk factors. Current research may be limited by stigmatization surrounding infertility and reproductive-altering surgeries (e.g. hysterectomy). Additionally, counseling in all stages of pregnancy is critical to achieving the best patient-centered outcomes.Different mechanisms have been proposed in lymphomatous involvement of the optic nerve. They include isolated optic nerve lymphoma, optic nerve lymphoma associated with primary central nervous system (CNS) lymphoma, or with systemic lymphoma. We present one case of non-Hodgkin lymphoma of the optic nerve in a Human Immunodeficiency Virus (HIV) patient and discuss the mechanism of metastasis, classification of optic nerve involvement with clinical and radiologic features as well as treatment options. Despite the uncommon nature of optic nerve infiltration by lymphoma, prompt evaluation should be considered in patients with a history of lymphoma and visual symptoms as delays in treatment can result in permanent vision loss. read more The recommended initial workup includes neuroimaging and cerebrospinal fluid evaluation. Treatment options are not standardized but include intravenous and intrathecal chemotherapy, corticosteroids, and radiation.
