Our aim was to examine the effect of a smartphone’s presence on learning and memory among undergraduates. A total of 119 undergraduates completed a memory task and the Smartphone Addiction Scale (SAS). As predicted, those without smartphones had higher recall accuracy compared to those with smartphones. Results showed a significant negative relationship between phone conscious thought, “how often did you think about your phone”, and memory recall but not for SAS and memory recall. Phone conscious thought significantly predicted memory accuracy. GS-441524 order We found that the presence of a smartphone and high phone conscious thought affects one’s memory learning and recall, indicating the negative effect of a smartphone proximity to our learning and memory.

Right heart thrombus (RHT) is a medical condition associated with acute pulmonary embolism and congestive cardiac failure. Rapid recognition is essential for instituting early treatment and preventing adverse outcomes.

A 55-year-old male presented with symptoms of congestive cardiac failure complicated by cardiac arrest. Initial transthoracic echocardiography (TTE) demonstrated moderate impairment of both ventricles and a moderately dilated right ventricle (RV). After initial improvement with heart failure treatment, the patient subsequently had a second cardiac arrest. Bedside TTE revealed complete RV obstruction by thrombus, and intravenous thrombolysis was immediately instituted, with complete dissolution of the thrombus and haemodynamic recovery 15 minutes after treatment. Unfortunately, the patient suffered significant hypoxic brain injury and did not survive.

RHT can manifest acutely in a dramatic fashion with cardiac arrest. Bedside TTE is key to making a rapid diagnosis in this setting to allow early administration of thrombolytic therapy.

Right heart thrombus (RHT) may manifest acutely as cardiac arrest in patients with underlying cardiomyopathy.Echocardiography is essential for rapid diagnosis of RHT.Thrombolysis can lead to rapid thrombus dissolution and haemodynamic improvement.

Adenosine deaminase (ADA) measurement has become an important tool in the timely diagnosis of this infection. However, ADA elevation in bodily fluids is not pathognomonic of TB infection. We present the case of a 70-year-old woman, undergoing treatment for pleural TB, diagnosed based on elevated ADA levels in a pleural effusion. Due to worsening symptoms she was readmitted, and the previous diagnosis was reconsidered. Thoracocentesis was repeated and cytometry analysis of the fluid was performed, showing the presence of diffuse large B cell lymphoma (DLBCL). DLBCL is the most frequently occurring non-Hodgkin lymphoma (NHL). Pleural involvement is rare in the initial stages. ADA elevation >250 U/l should raise suspicion of malignancy, especially in association with markedly elevated LDH levels. The purpose of this case report is to highlight that in the absence of microbiologic or histologic confirmation, a presumptive TB diagnosis should not be lightly made, and alternative diagnoses should be systematically ruled out.

Elevated ADA levels are not pathognomonic of TB infection.Lymphocytic pleural effusion requires a systematic diagnostic approach.Very high levels of ADA should arouse suspicion of lymphoma.

arcoidosis is a multisystemic disease producing non-caseating granulomas. The aetiology and pathogenesis are unknown. We herewith report an atypical case of cutaneous sarcoidosis.

A 50-year-old female presented with an onset of multiple subcutaneous nodules on her 4 limbs. These nodules appeared concomitantly with the initiation of radioactive iodine therapy for papillary thyroid cancer. These nodules were not obvious on inspection of the skin, but easily felt on palpation.The biopsy of the subcutaneous nodules revealed hypodermic non-caseating granulomas consistent with sarcoidosis. The patient underwent an 18F-fluorodeoxyglucose positron emission tomography (PET) scan study that revealed, besides the subcutaneous nodules, multiple hypermetabolic mediastinal lymphadenopathies and cervical adenopathies. Biopsy of the mediastinal lymphadenopathy showed neither granulomas nor neoplastic cells. Cervical biopsy revealed neoplastic cells of thyroid origin. Laboratory tests were normal. Bronchoalveolar lavage sesis of sarcoidosis is poorly understood, as well as the environmental factors involved.Radioactive iodine therapy for thyroid cancer treatment may be an environmental trigger.The immunological changes induced by radioiodine, especially with respect to the Th1/Th2 ratio, may promote occurrence of sarcoidosis in genetically predisposed patients.Pityriasis rubra pilaris (PRP) is a rare chronic inflammatory papulosquamous dermatosis affecting both adults and children. Six subtypes of PRP have been described. Recently, the management of PRP with biologic immunosuppressive agents regularly used in psoriasis has been supported by several case reports and series. Ustekinumab is an anti-IL12/23 IgG1 kappa human monoclonal antibody. It has been approved for the treatment of Crohn’s disease, plaque psoriasis, psoriatic arthritis and ulcerative colitis. It has also been reported to be effective as an off-label treatment for PRP. Current data are equivocal regarding infectious disease risk with ustekinumab administration. We describe a case of meningococcal and HSV-2 infection of the central nervous system in a patient being treated with ustekinumab for PRP.

The administration of biologic immunosuppressive agents can result in severe life-threatening infections.Research is required on the infection potential of ustekinumab.Physicians should be aware of the possibility of infectious disease when prescribing biologic agents.
