Rhupus arthropathy as the presenting manifestation in Juvenile SLE: a case report

An 8.5-year-old girl was referred with swelling of both knees lasting for two years. ANA was found as negative. She was diagnosed as oligoarticular JIA. After two years of follow-up, thrombocytopenia was detected during routine screening. Her ANA and anti ds-DNA antibodies also became positive, with low levels of C3 and C4. She was diagnosed as Juvenile SLE, meeting the criteria cytopenia, positive immunoserology (anti dsDNA), positive ANA test, and four years of ongoing chronic arthritis, so called as "rhupus arthropathy". We should be aware of the several initial incomplete presentations of lupus in children. We should be careful in monitoring the serious manifestations of the disease in juvenile lupus patients with rhupus arthropathy, and consider the poor response to standard disease modifying agents

CHFR (Checkpoint with fork-head associated and ring finger)

Growing evidence in mice, primary human tumors, and mammalian cell culture models indicate that CHFR may function as a potent tumor suppressor. CHFR functions as part of an early G2/M checkpoint, more specifically in antephase. Antephase refers to late G2 when chromosome condensation starts. This early mitotic checkpoint causes a delay in chromosome condensation in response to mitotic stresses. The human CHFR gene was originally identified during a search for novel cell cycle checkpoint proteins that have fork-head associated domains. Initial analysis indicated that the CHFR-associated G2/M checkpoint was inactivated in a subset of cancers as demonstrated by high mitotic indices (a high percentage of cells that have condensed chromosomes) in response to exposure to the microtubule poison, nocodazole, due to lack of CHFR expression or CHFR mutations in various cancers. Many other studies showed promoter hypermethylation leading to low/no expression of CHFR

Treatment of acne with intermittent and conventional isotretinoin: a randomized, controlled multicenter study

Oral isotretinoin is the most effective choice in the treatment of severe acne. Application of isotretionin to acne has been expanded to treat those patients with less severe but scarring acne who are responding unsatisfactorily to conventional therapies. However, its use is associated with many side effects, some of which can result in very disastrous consequences. Data related with intermittent isotretinoin therapy is still limited. Our aim was to asses the efficacy and tolerability of two different intermittent isotretinoin courses and compare them with conventional isotretinoin treatment. In this multicenter and controlled study, 66 patients with moderate to severe cases were randomized to receive either isotretionin for the first 10 days of each month for 6 months (group 1), or each day in the first month, afterwards the first 10 days of each month for 5 months (group 2) or daily for 6 months (group 3). The drug dosage was 0.5 mg/kg/day in all groups. Patients were followed-up for 12 months. Efficacy values were evaluable for 22 patients in group 1, 19 patients in group 2, and 19 patients in group 3. Acne scores in each group were significantly lower at the end of treatment and follow-up periods (P < 0.001). When patients were evaluated separately as moderate (n = 31) and severe (n = 29), no statistically significant differences were obtained among the treatment protocols in patients with moderate acne. However, there was a significant difference between groups 1 and 3 to the response of the treatments in severe acne patients at the end of follow-up period (P = 0.013). The frequency and severity of isotretionin-related side effects were found to be lower in groups 1 and 2 compared with group 3. Intermittent isotretinoin may represent an effective alternative treatment, especially in moderate acne with a low incidence and severity of side effects. The intermittent isotretinoin can be recommended in those patients not tolerating the classical dosage

Epidemiology of pemphigus in Turkey: One-year prospective study of 220 cases

Pemphigus is a group of rare and life-threatening autoimmune blistering diseases of the skin and mucous membranes. Although they occur worldwide, their incidence shows wide geographical variation, and prospective data on the epidemiology of pemphigus are very limited. Objective of this work is to evaluate the incidence and epidemiological and clinical features of patients with pemphigus in Turkey. All patients newly diagnosed with pemphigus between June 2013 and June 2014 were prospectively enrolled in 33 dermatology departments in 20 different provinces from all seven regions of Turkey. Disease parameters including demography and clinical findings were recorded. A total of 220 patients were diagnosed with pemphigus during the 1-year period, with an annual incidence of 4.7 per million people in Turkey. Patients were predominantly women, with a male to female ratio of 1:1.41. The mean age at onset was 48.9 years. Pemphigus vulgaris (PV) was the commonest clinical subtype (n=192; 87.3%), followed by pemphigus foliaceus (n=21; 9.6%). The most common clinical subtype of PV was the mucocutaneous type (n=83; 43.2%). The mean Pemphigus Disease Area Index was 28.14±22.21 (mean ± Standard Deviation).  The incidence rate of pemphigus in Turkey is similar to the countries of South-East Europe, higher than those reported for the Central and Northern European countries and lower than the countries around the Mediterranean Sea and Iran. Pemphigus is more frequent in middle-aged people and is more common in women. The most frequent subtype was PV, with a 9-fold higher incidence than pemphigus foliaceus.   </p

Turing Test: 50 Years Later

The Turing Test is one of the most disputed topics in artificial intelligence, philosophy of mind, and cognitive science. This paper is a review of the past 50 years of the Turing Test. Philosophical debates, practical developments and repercussions in related disciplines are all covered. We discuss Turing's ideas in detail and present the important comments that have been made on them. Within this context, behaviorism, conscioussness, the `other minds' problem, and similar topics in philosophy of mind are discussed. We also cover the sociological and psychological aspects of the Turing Test. Finally, we look at the current situation and analyze programs that have been developed with the aim of passing the Turing Test. We conclude that the Turing Test has been, and will continue to be, an influential and controversial topic

Life-Threatening Complication of Percutaneous Transthoracic Fine-Needle Aspiration Biopsy: Systemic Arterial Air Embolism

Computed tomography-guided percutaneous transthoracic fine-needle aspiration biopsy of lung lesions is a well known diagnostic technique. Nevertheless, it has some complications; such as pneumothorax, intraparenchymal hemorrhage and hemoptysis, which are not rare. Air embolism is one of the rare but potentially fetal complications of this procedure. Herein, we report the case of a 69-year-old male, in which case of systemic air embolism developed after the performance of lung biopsy. Early diagnosis and prompt oxygen therapy is crucial for patient's survival so careful reviewing of the obtained computed tomography images during the biopsy may prevent a missing systemic air embolism and provide an adequate therapy
