Two cases of radiation-induced sarcoma after radiation therapy in nasopharyngeal carcinoma

We report two cases of radiation-induced sarcoma after chemoradiation therapy in nasopharyngeal carcinoma. Case 1: A 40-year-old man developed a malignant peripheral nerve sheath tumor (MPNST) in the posterior floor of the nasal cavity 10 years after treatment for nasopharyngeal cancer. Case 2: A 64 year-old man developed a malignant fibrous histiocytoma (MFH) of the lower gum 10 years after treatment of nasopharyngeal cancer. Despite radical surgery, the man with MPNST had a recurrent tumor and died of the disease.     

The effect of sensory stories on targeted behaviors in preschool children with autism

This study examined the effectiveness of Sensory Stories on "circle time" behaviors in preschool children with autism. This single-system ABA design with a convenience sample of four participants consisted of one week for each A phase and two weeks for the B phase. The intervention phase (B) consisted of reading a Sensory Story from one to three times per day to each child. Three children had a positive change in their behavior after reading a Sensory Story. The fourth child also showed a positive change in his behavior; however, behaviors were already improving during baseline, making interpretation difficult. Further research is suggested to determine the effectiveness of Sensory Stories with other age groups and populations.     

Risk factors for out-of-home custody child care among families with alcohol and substance abuse problems

AIM: To study the risk of children to mothers with alcohol and/or substance abuse related problems for early childhood out-of-home care in Finland. METHODS: A population-based cross-sectional retrospective analysis of 526 pregnant women attending special outpatient clinics during 1992-2001 and their 626 offspring, with out-of-home care data until 2003 provided by the National Child Welfare Register. RESULTS: Fifty percent (95% confidence interval 46-54%) were at some point and 38% (34-42%) by the age of two years, in out-of-home care. Out-of-home care was associated with maternal care for substance abuse after delivery, nonemployment, housing, daily smoking during pregnancy, increasing number of previous births, mother in custody in her childhood, maternal education, previous child in custody, drug in urine during pregnancy, unplanned pregnancy, partner with significant abuse, regular health-care contact for abuse, daily alcohol consumption before and/or during pregnancy, newborn not discharged with mother, neonatal abstinence symptoms (NAS), intensified perinatal surveillance or NICU, and delayed discharge from hospital. CONCLUSIONS: There is a substantial risk of children born to mothers with significant alcohol and/or substance abuse related problems for out-of-home care during early childhood. Factors identified during the pre- and perinatal period are associated with this risk.     

Apoptosis and thymidylate synthase inductions by 5-fluorouracil in gastric cancer cells with or without p53 mutation.

We studied apoptosis and thymidylate synthase (TS) inductions by 5-fluorouracil (5-FU) in gastric cancer cells with wild-type p53 (MKN-45 and MKN-74) and with mutated p53 (MKN-28 and KATO-III). Apoptotic inductions in MKN-45 and MKN-74 were stronger than those in MKN-28 and KATO-III, suggesting that wild-type p53 may contribute to the induction of apoptosis. After continuous exposure to 0.1 microg/ml of 5-FU for 96 h, no TS induction was obtained in KATO-III, while approximately twice the amount of TS was observed compared to non-treatment cells in MKN-45, MKN-74, and MKN-28. The results of immunohistochemical staining for TS and p53 showed no relation between these two protein expressions in endoscopic biopsy specimens of 25 patients with advanced gastric cancer. These results indicated that p53 status may not play a pivotal role in regulating TS expression. We found no significantly different effects of 5-FU between intermittent (repeat of 24-h continuous infusion and 24-h drug-free) and continuous treatments in either MKN-28 or stem cells (CD34+ hematopoietic progenitor cells) when the same area under the time-concentration curve of 5-FU was administered. The TS induction in MKN-28 cells by intermittent treatment was significantly higher than that by continuous treatment; however, most TSs in both types of 5-FU treatment cells were of the inactive form, i.e., TS bound to FdUMP, a 5-FU metabolite. Therefore, neither intermittent nor continuous treatment appears to induce 5-FU resistance related to the level of increment free TS. In conclusion, our observations suggested that p53 mutation may be associated with apoptotic induction by 5-FU; however, p53 status may not strongly affect TS induction by 5-FU. Intermittent treatment can be replaced with continuous treatment without causing 5-FU resistance.     

Cibenzoline, an ATP-sensitive K(+) channel blocker, binds to the K(+)-binding site from the cytoplasmic side of gastric H(+),K(+)-ATPase.

1. Cibenzoline, (+/-)-2-(2,2-diphenylcyclopropyl-2-imidazoline succinate, has been clinically used as one of the Class I type antiarrhythmic agents and also reported to block ATP-sensitive K(+) channels in excised membranes from heart and pancreatic beta cells. In the present study, we investigated if this drug inhibited gastric H(+),K(+)-ATPase activity in vitro. 2. Cibenzoline inhibited H(+),K(+)-ATPase activity of permeabilized leaky hog gastric vesicles in a concentration-dependent manner (IC(50): 201 microM), whereas no effect was shown on Na(+),K(+)-ATPase activity of dog kidney (IC(50): >1000 microM). Similarly, cibenzoline inhibited H(+),K(+)-ATPase activity of HEK-293 cells (human embryonic kidney cell line) co-transfected with rabbit gastric H(+),K(+)-ATPase alpha- and beta-subunit cDNAs (IC(50): 183 microM). 3. In leaky gastric vesicles, inhibition of H(+),K(+)-ATPase activity by cibenzoline was attenuated by the addition of K(+) (0.5 - 5 mM) in a concentration-dependent manner. The Lineweaver-Burk plot of the H(+),K(+)-ATPase activity shows that cibenzoline increases K(m) value for K(+) without affecting V(max), indicating that this drug inhibits H(+),K(+)-ATPase activity competitively with respect to K(+). 4. The inhibitory effect of H(+),K(+)-ATPase activity by cibenzoline with normal tight gastric vesicles did not significantly differ from that with permeabilized leaky gastric vesicles, indicating that this drug reacted to the ATPase from the cytoplasmic side of the membrane. 5. These findings suggest that cibenzoline is an inhibitor of gastric H(+),K(+)-ATPase with a novel inhibition mechanism, which inhibits gastric H(+),K(+)-ATPase by binding its K(+)-recognition site from the cytoplasmic side.     

Vertebral Artery Dissection in Turner's Syndrome: Diagnosis by Magnetic Resonance Imaging

Aortic artery dissection is a rare but well-recognized complication of Turner's syndrome. Isolated carotid or vertebral artery dissection has not previously been reported. The authors report the clinical and magnetic resonance imaging findings in a 30-year-old woman with Turner's syndrome who developed a high cervical spinal cord infarction with a Brown-Sequard syndrome owing to bilateral vertebral artery dissection. The diagnosis and management of the case is reviewed.     

Provider uptake of extragenital screening for gonorrhea and chlamydia in a cohort of Air Force members with incident HIV diagnosis

The prevalence of Neisseria gonorrhea (GC) and Chlamydia trachomatis (CT) is higher at extragenital anatomic sites among men who have sex with men (MSM) with HIV infection. Although national guidelines recommend that all MSM with HIV infection undergo screening for extragenital sexually transmitted infections (EG-STIs), uptake is low in many primary care settings. We evaluated EG-STI screening by primary care providers (PCPs) for US Air Force (USAF) members with incident HIV infection. All USAF members with incident HIV infection who received initial HIV specialty care with Infectious Disease (ID) providers at Brooke Army Medical Center from 2016 to 2018 (n = 98) were included. A retrospective chart review was conducted to evaluate STI screening performed by PCPs within 1 week of HIV diagnosis compared to screening at entry into ID care. Demographic, clinical, laboratory and behavioral risk data were collected. STI screening included GC/CT EG-STIs, urethral GC/CT, syphilis, and hepatitis B and C. Patients were predominantly male (98%) with a median age of 26 (IQR 23, 32) years at HIV diagnosis. A previous history of STIs was reported in 53 (54%) patients and the majority of males self-identified as MSM (66%) or bisexual (23%). The median time from HIV diagnosis to ID evaluation was 26 days (IQR 9, 33). PCPs performed any STI screening in 61 (62%) patients. EG-STI screening was conducted in 3 (3%) patients overall and in (3%) MSM/bisexuals. A total of 31 (32%) patients had missed STIs; the majority due to EG-STIs of the rectum (59%) and pharynx (19%). All EG-STIs would have been missed by urethral GC/CT screening alone. EG-STI screening uptake was low among PCPs evaluating USAF members with incident HIV infection. Underutilization of EG-STI screening can result in missed infections and forward transmission of GC/CT. Barriers to low uptake need to be explored.     

Psychotic Disorders in Adolescence and Later Long-term Exclusion From Education and Employment

Background and hypothesisPsychotic disorders have been associated with not being in education, employment, and training (NEET). There is a lack of knowledge on the importance of risk markers for NEET among people with psychotic disorders and what rehabilitation they receive.Study designWe based our research on the register-based 1987 Finnish Birth Cohort study, which included all live births in Finland during that year. The study cohort were 288 people who had been diagnosed with psychotic disorders during 2004–2007, when they were 16–20 year old, and 55 883 who had not. We looked at the national register data for those subjects in 2008–2015, when they were 20–28 year old, and compared any associations between sociodemographic factors and NEET status.Study resultsNEET for more than 5 year affected 2.2% of those without psychosis, 35.8% of those with any nonaffective psychotic disorder, and 57.0% of those with schizophrenia or schizoaffective disorders. Family-related risk factors were weaker predictors of long-term NEET in subjects with psychotic disorders than other cohort members. Having a psychotic disorder plus long-term NEET was associated with not applying for upper secondary education, not finishing upper secondary education, parents receiving welfare benefits, being diagnosed with schizophrenia or schizoaffective disorders and being hospitalized for psychosis. Only 24.3% with psychotic disorders had participated in vocational rehabilitation.ConclusionsA diagnosis of psychosis in adolescence is independently associated with serious long term functional disability. Among those with psychotic disorders, educational problems are markers for adverse labor market outcomes. Despite this, vocational rehabilitation is seldom provided.
