An Unusual Hypoxia Patient
BY GORDON MURPHY, PA-C, MPHThe patient was blue, her primary care physician noted. Quite literally, in fact.The 38-year-old woman had sought care for a recurrent urinary tract infection, and that's when her primary care physician found her pulse oximetry to be 74%. He was concerned about hypoxia and asked us to evaluate her.The patient reported taking an SSRI for anxiety and having a hormone-eluting IUD. She had previously had a Roux-en-Y gastric bypass. She said she had a headache, but had been instructed not to take NSAIDs. She said she had just finished a course of Cipro for her UTI, but continued to be symptomatic with urinary frequency, urgency, and burning, for which she had been taking the over-the-counter drug phenazopyridine (Azo, Pyridium). Her exam was otherwise unremarkable, with no fever, chest pain, or shortness of breath.Her vital signs were a pulse of 104 bpm, respirations of 24 bpm, blood pressure of 138/74 mm Hg, and SpO2 of 92% on 4 lpm via nasal cannula (low 80s on arrival). The patient was cyanotic, and her lips and fingers were blue, but she was not dyspneic in conversation and walked to the bathroom without difficulty. She was mildly tachypneic and tachycardic, but her lung sounds were clear and she had no cardiac murmurs or thrills, abdominal abnormalities, or peripheral edema.Her white blood cell count, hemoglobin, hematocrit, and D-dimer were within normal limits, and her arterial blood gas was unremarkable, not acidotic, and she had no oxyge...
ConclusionFDG-PET/CT may steer the diagnosis (particularly thanks to a relatively high PPV and value of semiquantitative measurements), but cannot always classify vertebral bone lesions as malignant or benign with sufficient certainty. In these cases, biopsy and/or follow-up remain necessary to establish a final diagnosis.
ConclusionWe achieved promising results with this computer-aided diagnosis method that we tried to develop using convolutional neural networks based on transfer learning. This method can help clinicians for the diagnosis of hip osteoarthritis while interpreting plain pelvic radiographs, also provides assistance for a second objective interpretation. It may also reduce the need for advanced imaging methods in the diagnosis of hip osteoarthritis.
AbstractThe biceps brachii myotendinous unit, particularly the long head of the biceps tendon and its labral attachment, is a common cause of shoulder and arm pain. Its complex anatomy and normal variations can present a challenge when interpreting MR images. The purpose of this manuscript is to review the proximal biceps anatomy, variants, pathology, and post-operative appearance as seen on MRI. Recent data regarding the accuracy of clinical examination and MRI will be summarized.
ConclusionWe report statistically significant differences in the T1 ρ value in the superficial and middle zones of the lateral patella in patients with patellofemoral pain syndrome who had no abnormalities seen on conventional MRI sequences, suggesting an alteration the macromolecular structure of the cartilage in this population.
We report a case of a 55-year-old patient being resuscitated emergently with proximal humeral intraosseous infusion for cardiac and respiratory arrest secondary to status epilepticus. After successful resuscitation and removal of the intraosseous cannula, the patient noted new-onset shoulder pain. The patient was ultimately diagnosed with an iatrogenic fracture of the anatomic neck of the humerus through the intraosseous needle tract when the appropriate history was obtained in conjunction with cross-sectional imaging. As the use of intraosseous access expands, such fractures may well be seen more frequently. Intraosseous ...
AbstractA 37-year-old man presented with a 2-year history of left hip pain. Pretherapeutic imaging demonstrated a 4 cm osteoblastoma located in the intertrochanteric region of the proximal femur, surrounded by extensive bone marrow edema. After multidisciplinary meeting, percutaneous cryoablation was decided and performed under computed tomography guidance using three cryoprobes to match the exact size and shap e of the tumor, resulting in complete resolution of symptoms. Magnetic resonance imaging follow-up demonstrated resolution of the bone marrow edema pattern and ingrowth of fat at the periphery of the ablation ...

Conclusion: The findings show a high prevalence of disordered eating attitude among high school female students in Al-Madinah city. Younger girls and those of the first scholastic level showed higher disordered eating attitude.
