Abstract
This report is the first to present the case of a patient who developed bacterial abscess-forming prostatitis while undergoing treatment with adalimumab, a tumor necrosis factor-alpha blocking therapy, for hidradenitis suppurativa. A 36-year-old male presented with persistent anogenital pain and dysuria for approximately three weeks. Two days before presentation at the emergency room (ER), a rubber band ligation was performed to address suspected hemorrhoids stages I-II. In the ER, clinical and laboratory examinations suggested acute prostatitis, prompting the initiation of antibiotic therapy. In the absence of an adequate response, magnetic resonance imaging was performed, which identified a complex abscess and fistulation system originating from the right prostatic lobe. Following the insertion of a drain, adalimumab was discontinued, and antibiotic therapy was intensified, resulting in the resolution of the abscess. After six weeks, follow-up showed the patient to be free of symptoms. This case highlights a rare adverse event of patients using immunomodulating medications and may help physicians to manage similar cases in the future. Immunomodulating drugs can lead to the development of prostatic abscesses in young patients, necessitating attentive and careful clinical examination with a low threshold for further diagnostic workup in uncommon case presentations.

Abstract
BACKGROUND There is evidence linking metformin to improved prostate cancer-related outcomes. PATIENTS AND METHODS Twenty-five men with metastatic castration-resistant prostate cancer and prostate-specific antigen (PSA) progression while receiving treatment with abiraterone from 3 Swiss centers were included in this single-arm phase 2 trial between November 2013 and September 2016. Metformin was added to abiraterone continuously at 1000 mg twice daily in uninterrupted 4-week cycles. The primary end point was the absence of disease progression at 12 weeks (PFS12). The Fleming single-stage design was applied. With a 5% significance level and 80% power, 25 patients were required to test PFS12 ≤ 15% (H0) compared to ≥ 35% (H1). Secondary end points included toxicity and safety issues. The study was registered at ClinicalTrials.gov (NCT01677897). RESULTS The primary end point PFS12 was 12% (3 of 25 patients) (95% confidence interval, 3-31). Most patients had PSA progression, almost half had radiographic progression, but only 1 patient had symptomatic progression. Eleven (44%) of 25 patients had grade 1 and 2 patients each grade 2 (8%) or grade 3 (8%) gastrointestinal toxicity (nausea, diarrhea, loss of appetite). One patient discontinued treatment at week 5 because of intolerable grade 3 diarrhea. CONCLUSION The addition of metformin to abiraterone for patients with metastatic castration-resistant prostate cancer and PSA progression while receiving abiraterone therapy does not affect further progression and has no meaningful clinical benefit. A higher-than-expected gastrointestinal toxicity attributed to metformin was observed.

Abstract
Background Adding abiraterone acetate with prednisolone (AAP) or docetaxel with prednisolone (DocP) to standard-of-care (SOC) each improved survival in systemic therapy for advanced or metastatic prostate cancer: evaluation of drug efficacy: a multi-arm multi-stage platform randomised controlled protocol recruiting patients with high-risk locally advanced or metastatic PCa starting long-term androgen deprivation therapy (ADT). The protocol provides the only direct, randomised comparative data of SOC + AAP versus SOC + DocP. Method Recruitment to SOC + DocP and SOC + AAP overlapped November 2011 to March 2013. SOC was long-term ADT or, for most non-metastatic cases, ADT for ≥2 years and RT to the primary tumour. Stratified randomisation allocated pts 2 : 1 : 2 to SOC; SOC + docetaxel 75 mg/m2 3-weekly×6 + prednisolone 10 mg daily; or SOC + abiraterone acetate 1000 mg + prednisolone 5 mg daily. AAP duration depended on stage and intent to give radical RT. The primary outcome measure was death from any cause. Analyses used Cox proportional hazards and flexible parametric models, adjusted for stratification factors. This was not a formally powered comparison. A hazard ratio (HR) <1 favours SOC + AAP, and HR > 1 favours SOC + DocP. Results A total of 566 consenting patients were contemporaneously randomised: 189 SOC + DocP and 377 SOC + AAP. The patients, balanced by allocated treatment were: 342 (60%) M1; 429 (76%) Gleason 8-10; 449 (79%) WHO performance status 0; median age 66 years and median PSA 56 ng/ml. With median follow-up 4 years, 149 deaths were reported. For overall survival, HR = 1.16 (95% CI 0.82-1.65); failure-free survival HR = 0.51 (95% CI 0.39-0.67); progression-free survival HR = 0.65 (95% CI 0.48-0.88); metastasis-free survival HR = 0.77 (95% CI 0.57-1.03); prostate cancer-specific survival HR = 1.02 (0.70-1.49); and symptomatic skeletal events HR = 0.83 (95% CI 0.55-1.25). In the safety population, the proportion reporting ≥1 grade 3, 4 or 5 adverse events ever was 36%, 13% and 1% SOC + DocP, and 40%, 7% and 1% SOC + AAP; prevalence 11% at 1 and 2 years on both arms. Relapse treatment patterns varied by arm. Conclusions This direct, randomised comparative analysis of two new treatment standards for hormone-naïve prostate cancer showed no evidence of a difference in overall or prostate cancer-specific survival, nor in other important outcomes such as symptomatic skeletal events. Worst toxicity grade over entire time on trial was similar but comprised different toxicities in line with the known properties of the drugs. Trial registration Clinicaltrials.gov: NCT00268476.

Abstract
We report a young male aged 20 who has suffered two episodes of Leydig cell tumor of the testis, the second occurring 5 years after the first in the contralateral testis. The case is outlined briefly, with references taken from the literature. This young man's history is exceptional as this type of tumor is infrequent, and metachronous bilateral presentation extremely rare.

Abstract
The circumstellar silicon carbide (SiC) grain X57 from the Murchison meteorite contains large amounts of radiogenic calcium-44 (20 times its solar system abundance) and has an anomalous silicon isotopic composition, different from other circumstellar SiC grains. Its inferred initial 44Ti/Si and 44Ti/48Ti ratios are 1.6 x 10(-4) and 0.37. In addition, it contains radiogenic magnesium-26; the inferred initial 26Al/27Al ratio is 0.11. The isotopic and elemental data of X57 can be explained by selective mixing of matter from different zones of a typical type II supernova of 25 solar masses during its explosion. The high 44Ti/Si ratio requires contributions from the innermost nickel zone of the supernova to the SiC condensation site, as similarly suggested by astronomical observations.

Abstract
We report the results of SIMS isotopic analyses of carbon, nitrogen, oxygen, and silicon made on 849 small (approximately 1 micrometer) individual silicon carbide grains from the Murchison meteorite. The isotopic compositions of the major elements carbon and silicon of most grains (mainstream) are similar to those observed in larger grain studies suggesting an AGB star origin of these grains. In contrast, the trace element nitrogen shows a clear dependency on grain size. 14N/15N ratios increase with decreasing grain size, suggesting different stellar sources for grains of different size. Typically observed 14N/15N ratios in the small grains of this study are approximately 2700, clearly larger than the values expected from model calculations of AGB stars. In addition to the three dredge-up episodes characteristic for the evolution of AGB stars, extra-mixing of CNO-processed matter in low mass AGB stars appears to be a promising possibility in order to explain the high 14N/15N ratios of the small circumstellar SiC grains. A small fraction of grains shows a silicon isotopic signature not observed in larger circumstellar SiC grains from Murchison. Their stellar origin is still uncertain. The minor type A, B, Y, and X grains were found to be present at a level of a percent, which is similar to their abundance in the larger-grain SiC separates from Murchison. Oxygen isotopic compositions are normal within the experimental uncertainties of several 10%, indicating that oxygen of stellar origin is rare or even absent in the SiC grains. We conclude that most of the oxygen is a contaminant which was introduced into the SiC grains after their formation, e.g., during sample processing in the laboratory. We identified a nitride grain, most likely Si3N4 with little carbon, with highly anomalous isotopic compositions (12C/13C = 157 +/- 33, 14N/15N = 18 +/- 1, delta 29 Si = -43 +/- 56%, delta 30 Si = -271 +/- 50%). The isotopic patterns of carbon, nitrogen, and silicon resemble those of the rare SiC X grains suggesting that these two rare constituents of circumstellar matter formed in the same type of stellar source, namely, Type II supernovae.

Abstract
Extremely low birthweight infants are attracting increasing attention in the medical literature, mainly in audits from selected hospitals not representative of the entire population of a country. The Swiss Neonatology Group gathered selected data on mortality, morbidity and medical treatment of all liveborn infants weighing between 500 and 999 g at birth for the years 1979-81, 1983-85 and 1989-91. The results were compared and completed with information from the Swiss Office of Statistics. From 1979-81 to 1989-91 the incidence of extremely low birthweight infants increased from 1.3 to 2.2 per thousand livebirths. At the same time the survival rate increased from 23% to 53%, resulting in three times more infants being discharged from hospital in this weight group. The number of days of mechanical ventilation, which is an indicator of intensity of care, increased from 320 days to 1440 days per year. In contrast to mortality, morbidity scarcely decreased within this 12-year period and was still considerable in 1989-91. 57% of the survivors had chronic lung disease and 15% had sepsis. Intracranial hemorrhage was present in 35% of the survivors and 71% of the deaths. Retinopathy was noted in 38% of survivors. These facts, which are representative of the whole of Switzerland, show the increasing medical and economic significance of this patient group. Before the implications of this development can be fully assessed, extremely low birthweight infants must be followed up until adult life.

Abstract
The effect of whole-body hyperthermia (41.5 degrees C, 2 h) on doxorubicin (DOX) tissue distribution and plasma pharmacokinetics was examined in rats bearing a subcutaneous fibrosarcoma. Tumour response to the hyperthermia regimen alone was minimal, but the combination of heat with DOX (5.0 mg/kg, i.v.) enhanced tumour growth delay. The combined therapy, however, showed increased toxicity to normal tissue (especially renal and cardiac). Although DOX levels in spleen tissue were higher in rats exposed to hyperthermia than in control normothermic rats, both groups had comparable levels of drug in tumour, heart, kidney, and small intestine tissue at all time-points examined. Compared with normothermic animals, hyperthermia-treated rats showed decreased DOX in the mean area under the concentration-time curve (AUC) and decreased plasma DOX t1/2 but increased plasma drug clearance. These heat-mediated alterations in DOX pharmacokinetic parameters, however, do not account for the significant increases in thermochemotherapy-mediated cytotoxicities observed in tumour, and in normal renal and cardiac tissues.
