Notes

Constitutionnel cause of nature involving PPM1H phosphatase pertaining to Rab GTPases.
Consolidation was detected with 100% sensitivity. Sensitivity and PPV for the detection of ground-glass opacities (GGOs) were 77.7% and 53.8%, respectively. T2 HASTE axial had the fewest image artefacts. Respiratory triggered MR pulse sequence did not add any significant diagnostic information as compared to the non-respiratory triggered MR pulse sequences. Conclusions Sensitivity for detecting small nodules and GGOs on MR is poor; CT scan remains the imaging modality of choice for the evaluation of pulmonary infections in immunocompromised patients. However, MRI can be used in the follow-up imaging of these patients.

We aimed at evaluating the soft tissue arthritic changes associated with pain in hemiplegic knees of stroke patients in our environment. Material and methods Hemiplegic and non-hemiplegic knees of 48 stroke patients as well as both knees of 26 apparently healthy controls were evaluated with a 7.5-12 MHz linear ultrasound probe. History of knee pain, and socio-demographic, laboratory, and clinical data were recorded for all study participants. Muscle tone and power as well as functional ambulatory category (FAC) were graded for the stroke patients. Data was analysed using SPSS version 20. Results Pain was reported more often in hemiplegic than non-hemiplegic knees (n = 16 vs. n = 6, p = 0.021). The frequencies of soft tissue arthritic changes found, which included reduced lateral and medial femoral cartilage thickness, suprapatellar effusion, and irregular cartilage-bone margin, were similar between hemiplegic and non-hemiplegic knees (p > 0.05). Suprapatellar effusion and reduced lateral femoral cartilage thickness were more prevalent in the hemiplegic knees compared to the healthy control knees (p less then 0.05). Stroke patients with pes anserinus tendinosis had greater risk of hemiplegic knee pain (HKP) when compared to stroke patients without this lesion (OR = 10; 95% CI 1.7-61). check details FAC, muscle tone, and power showed no association with HKP. Conclusions Soft tissue arthritic changes associated with knee pain are comparable between hemiplegic and non-hemiplegic knees of stroke patients. The risk of knee pain in stroke is higher in the presence of pes anserinus tendinosis.

Of course, this germ may also be resistant to other anti-tuberculosis drugs. Patients with extensively drug-resistant tuberculosis (XDR-TB) are also resistant to all types of fluoroquinolone and at least one of the three injectable medications amikacin, clarithromycin, or kanamycin, in addition to isoniazid and rifampin. Therefore, the main objective of the current study was to evaluate and compare the computed tomography (CT) scan findings of MDR-TB and XDR-TB patients. Material and methods In this comparative descriptive cross-sectional study 45 consecutive TB patients who referred to Masih Daneshvari Hospital, Tehran, Iran from 2013 to 2019 were enrolled. TB was diagnosed based on sputum smear and sensitive molecular and microbial tests. Patients were divided into two groups (MDR-TB and XDR-TB) based on two types of drug resistance. CT scan findings were compared for cavitary, parenchymal, and non-parere similar to those of patients with MDR-TB for cavitary, parenchymal, and non-parenchymal lung characteristics. However, patients with XDR-TB tend to have more parenchymal calcification and left-sided plural effusion. CT characteristics overlap between XDR-TB and those with MDR-TB. It can be concluded that CT scan features are not sensitive to the diagnosis.

Fat necrosis or inflammation are common findings in abdominal imaging. The most common pathologies that we encounter are epiploic appendagitis, omental infarction, mesenteric panniculitis, and encapsulated fat necrosis. Less common entities that can occur are pancreatic saponification, heterotopic mesenteric ossification, and pseudolipoma of the capsule of Glisson. These entities can mimic more urgent pathologies such as appendicitis, diverticulitis, or malignancies. Copyright © Polish Medical Society of Radiology 2020.Purpose Renal artery aneurysms (RAAs) are a rare vascular pathology with an estimated prevalence of 0.1% to 2.5%. Rupture of RAA is an extremely unusual cause of acute flank pain and haemodynamic instability with acute kidney failure and high mortality rate (20%). Case report A 37-year-old male with no relevant history presented to the Emergency Room with acute right flank pain. Initial examination revealed BP 90/60 mm Hg and tachycardia. Initial blood testing was unremarkable, with a haemoglobin level of 9.4 g/dl. Urinalysis revealed moderate blood. Ultrasound (US) examination depicted aneurysm of the right renal artery 6 x 6 cm, with signs of blood extravasation visible in colour and power Doppler. The patient was referred for urgent computed tomography angiography, which revealed active bleeding from the ruptured aneurysm with haematoma spreading into the right retroperitoneum. He was subjected to emergency endovascular treatment. The patient was treated by successful implantation of a Viabahn stent (GORE, Daleware, USA). Selective nephrography revealed lack of flow through one of the segmental arteries resulting from vasospasm due to the placement of the guiding wire necessary for safe stent implantation. Conclusions The authors present a rare case of spontaneous RAA rupture in a young male successfully treated with endovascular methods. Stent implantation required selective catheterisation of segmental arteries of the kidney, which resulted in the loss of one of them. However, control Doppler US disclosed no ischaemia and successful exclusion of the aneurysm. Copyright © Polish Medical Society of Radiology 2020.
