Australian and New Zealand Journal of Medicine. 1990; 20(2): 175-176

A 59-year-old Chinese man presented with a three month history of penile ulcers and abdominal pain. Syphilis and a gastric malignancy were diagnosed clinically. Biopsy of the genital and stomach ulcers revealed histiocytic granulomata containing numerous intracellular fungal bodies. Histoplasma capsulatum was subsequently cultured from the penile ulcer. Antifungal therapy was instituted. However the patient's general condition deteriorated rapidly and he died within two weeks of admission. A post-mortem liver biopsy showed numerous intracellular fungi.

Diagnosis of prostate cancer (PCa) is currently much reliant on the invasive and time-consuming transrectal ultrasound-guided biopsy of the prostate gland, particularly in light of the inefficient use of prostate-specific antigen as its biomarker. In the present study, we have profiled the sera of patients with PCa and benign prostatic hyperplasia (BPH) using the gel- and lectin-based proteomics methods and demonstrated the significant differential expression of apolipoprotein AII, complement C3 beta chain fragment, inter-alpha-trypsin inhibitor heavy chain 4 fragment, transthyretin, alpha-1-antitrypsin, and high molecular weight kininogen (light chain) between the two groups of patients' samples. Our data are suggestive of the potential use of the serum proteins as complementary biomarkers to effectively discriminate PCa from BPH, although this requires further extensive validation on clinically representative populations.

Urine of patients with early prostate cancer contains lower levels of light chain fragments of inter-alpha-trypsin inhibitor and saposin B but increased expression of an inter-alpha-trypsin inhibitor heavy chain 4 fragment

The present study was aimed at the identification of proteins that are differentially expressed in the urine of patients with prostate cancer (PCa), those with benign prostatic hyperplasia (BPH) and age-matched healthy male control subjects. Using a combination of 2DE and MS/MS, significantly lower expression of urinary saposin B and two different fragments of inter-alpha-trypsin inhibitor light chain (ITIL) was demonstrated in the PCa patients compared to the controls. However, only one of the ITIL fragments was significantly different between the PCa and BPH patients. When image analysis was performed on urinary proteins that were transferred onto NC membranes and detected using a lectin that binds to O-glycans, a truncated fragment of inter-alpha-trypsin inhibitor heavy chain 4 was the sole protein found to be significantly enhanced in the PCa patients compared to the controls. Together, these urinary peptide fragments might be useful complementary biomarkers to indicate PCa as well as to distinguish it from BPH, although further epidemiological evidence on the specificity and sensitivity of the protein candidates is required.

STUDY DESIGN: Qualitative study using individual in-depth interviews. OBJECTIVES: The objective of this study was to explore the factors influencing the choice of bladder management for male patients with spinal cord injury (SCI). SETTING: Public hospitals in Malaysia. METHODS: Semistructured (one-on-one) interviews of 17 patients with SCI; 7 were in-patients with a recent injury and 10 lived in the community. All had a neurogenic bladder and were on various methods of bladder drainage. Interviews were audio-recorded, transcribed verbatim and analyzed using thematic analyses. RESULTS: The choice of bladder management was influenced by treatment attributes, patients' physical and psychological attributes, health practitioners' influences and social attributes. Participants were more likely to choose a treatment option that was perceived to be convenient to execute and helped maintain continence. The influence of potential treatment complications on decision making was more variable. Health professionals' and peers' opinions on treatment options had a significant influence on participants' decision. In addition, patients' choices depended on their physical ability to carry out the task, the level of family support received and the anticipated level of social activities. Psychological factors such as embarrassment with using urine bags, confidence in self-catheterization and satisfaction with the current method also influenced the choice of bladder management method. CONCLUSION: The choice of bladder management in people with SCI is influenced by a variety of factors and must be individualized. Health professionals should consider these factors when supporting patients in making decisions about their treatment options.

Fracture of the penis

Fracture of the penis is not an uncommon urological emergency. Six patients with this injury, treated at the Institute of Urology, General Hospital, Kuala Lumpur, since 1988, were reviewed. Their ages ranged from 21 to 30 years old (mean 25). Four cases were self-inflicted by abnormal bending and 2 cases occurred during sexual intercourse. A sudden "cracking sound", violent pain, rapid flaccidity and deformity of the penis were documented. Duration of injury at presentation ranged from 12 to 90 hours (mean 35 hours). Primary repair of the tunica albuginea with absorbable suture was performed in all cases. The results of surgery was excellent, with restoration of normal function in 4 patients (2 patients defaulted follow-up). We advocate immediate surgical repair for this injury.
