Does St. John’s Wort cause regression in gastrointestinal system adenocarcinomas?

St. John’s Wort (SJW) is an old herb which has long been consumed widely for its anti-inflammatory, antiviral, and anti-depressive properties. Here we present a detailed clinical evaluation of three cases (two colon and one duodenal adenocarcinoma) with remarkable and intensive lymphoplasmocytic host reaction, at the basal part of tumor, intensive fibrosis, giant cells, plasma cell increase in lymph nodes and few giant cells in germinal centers in resection specimens. The observation of similar host reaction in those tumors having otherwise usual appearance was interesting. None of the cases received neoadjuvant chemoradiotherapy or additional treatment before surgery but only SJW. These cases are presented to increase the awareness about such cases. Further research is needed to reveal the possible effect of SJW, which has long been consumed for different treatment purposes, on human tumors.     

Self‐reported quantity of daily water intake and urine output in healthy young

Water is an essential nutrient and adequate intake and output of water is required for health maintenance. Water homeostasis is vital for life and optimal function and considerable interest surrounds the issue of recommendations for water consumption in healthy individuals. Few studies are available about self‐reported water intake and urine output. The aim of this study was to assess the quantity of water intake and urine output in 24‐h period in healthy young individuals. This prospective study was carried out on 31 students aged 18–24 years undergoing nursing education in a University during January 2011 in Sakarya, Turkey. Healthy young individuals were recruited for determination of the quantity of water taken in and urine excretion along 24 h; they recorded fluid input and urine output. The students collected the data during weekend break. In our study, the total daily fluid intake (mL) for females was 2082·6 ± 687·1 and the total daily fluid intake (mL) for males was 2720·8 ± 717·4. The total daily quantity of urine (mL) for females was 1623·4 ± 602·4 and the total daily quantity of urine (mL) for males was 1818·3 ± 420·6. This research may be the source for similar studies that could include seasonal changes, climates, cultures and different age groups.     

Bone measurements of infants with hyperbilirubinemia by quantitative ultrasound: the influence of phototherapy

Objective: The purpose of the current study was to investigate the possible effects of phototherapy on bone status of term infants evaluated by measurement of tibial bone speed of sound (SOS).

Materials and methods: The phototherapy group (n?=?30) consisted of children who had undergone phototherapy for at least 24?h and the control group (n?=?30) comprised children who had not received phototherapy. Blood samples were obtained from all infants for serum calcium, phosphorus, magnesium, alkaline phosphatase, parathyroid hormone and vitamin D concentrations. The left tibial quantitative ultrasound (QUS) measurements were performed using a commercial device.

Results: There was no statistically significant difference between phototherapy-exposed and nonexposed infants in terms of Ca, P, ALP, PTH and vitamin D levels. Comparison of bone SOS between the phototherapy-exposed and control group revealed no statistically difference. Also, no significant difference in Z-score for SOS was observed between those with or without exposure.

Conclusion: The data of our study indicate that phototherapy treatment has no impact on bone status in the hyperbilirubinemic infants. Although there is no statistically significant evidence of an excess risk of bone damage following phototherapy, studies with larger sample sizes and longer duration of follow-up are needed to gain a better understanding of its effects.     

Associations analysis of GSTM1, T1 and P1 Ile105Val polymorphisms with carpal tunnel syndrome

Oxidative stress was related with carpal tunnel syndrome (CTS). We aimed to clarify the associations between glutathione S-transferase (GST)M1, GSTT1 and GSTP1-Ile105Val polymorphisms and CTS. One hundred-forty patients with CTS and 97 healthy controls were enrolled in this study. Tinel and Phalen signs were noted as positive or negative. Functional and clinical status of patients was evaluated by the Boston Questionnaire. The intensity of hand and/or wrist pain was evaluated on 10 cm visual analog scale (VAS). We applied the polymerase chain reaction (PCR) to determine the polymorphisms of the GSTM1 and GSTT1 and the PCR-restriction fragment length polymorphism method for detecting the GSTP1-Ile105Val polymorphism. The M1 null genotype was significantly higher in patients with CTS compared to healthy controls, and the M1 null genotype seemed to increase the risk of CTS approximately two-fold (P?=?0.011; odds ratio (OR)?=?1.98; 95 % confidence interval (CI) 1.17–3.36). The M1 null, T1 present combined genotype was significantly higher in patients with CTS compared to healthy controls (P?=?0.043); however, it seemed not to increase the risk of CTS (P?=?0.14; OR?=?0.62; 95 % CI 0.33–1.76). We found significantly higher levels of the VAS, Boston Symptom Severity Scale and Phalen sign in patients with the Ile/Val or the Val/Val genotypes compared to those in patients with the Ile/Ile genotype (P?=?0.003, 0.004 and 0.044, respectively). We proposed that genes involved in the protection from oxidative stress may influence the susceptibility, clinical and functional status of CTS. The GSTM1 null genotype may be related with the development of CTS, whereas the Val allele of GSTP1-Ile105Val polymorphism may be associated with worse functional and clinical status in CTS.     

Acute anterior myocardial infarction due to aortosaphenous vein graft occlusion with very large thrombus burden

A 75-year-old man, with a previous history of myocardial infarction and three-vessel coronary artery bypass grafting, presented with an acute anterior ST-elevation myocardial infarction. The vein graft to the left anterior descending artery was occluded with heavy thrombus burden, and the other grafts were patent. After administering a bolus dose of tirofiban and then undergoing percutaneous coronary intervention without stenting to the left anterior descending artery saphenous vein graft, intracoronary thrombolytic infusion was performed to maintain the patency of the vein graft. The patient was asymptomatic after medical follow-up. This may be an effective treatment option in patients with large thrombus burden and requires further investigation through large-scale trials.
