Hematospermia: An Unusual Cause of Urology Emergency

Abstract Hematospermia is a distressing disorder in sexually active men resulting in great concern to the patient. We report an unusual case of hematospermia with an atypical presentation, involving a 54-year-old man presented with acute urinary retention after sexual intercourse. Although the causes are widely known, arteriovenous malformation as the cause of this disorder has not much been reported in the literature. Transcatheter embolization of internal pudendal artery is a promising option for hematospermia caused by arterial fistula or bleeding.

A Rare Case of Scrotal Basal Cell Carcinoma in the Presence of Metastatic Squamous Cell Carcinoma of the External Auditory Meatus and its Management Strategy

Basal cell carcinoma (BCC) of the scrotum is uncommon and its pathogenesis is not well understood. The clinical behaviour of scrotal BCC is thought to be more aggressive and has a higher metastatic potential than BCC of other regions. The mainstay of treatment for localized scrotal BCC is wide local excision, while metastatic disease may need systemic chemotherapy for palliative control. A rare clinical scenario of scrotal BCC presenting concurrently with another metastatic cancer has never been reported. The present case illustrates the diagnostic challenge and management dilemma due to simultaneous presentation of scrotal BCC and metastatic squamous cell carcinoma (SCC). A 70-year-old man complained of a non-healing scrotal ulcer while he was being investigated for metastatic squamous cell carcinoma (SCC) of the external auditory meatus. The scrotal lesion was initially thought to be metastatic SCC. It was later confirmed to be BCC with biopsy and histopathological examination. He underwent surgical resection of the scrotal BCC for local control followed by palliative chemotherapy with cisplatin and radiotherapy for lymph node metastases. He remained well and did not have any local recurrence following 6 months after palliative treatment. Surgery coupled with palliative chemoradiation can offer good quality of life for patients with scrotal BCC and concurrent metastatic SCC.

Two Cases of Pseudohyperkalemia that Occurred after Emergency Splenectomy: What Goes Up, Will Come Down

Pseudohyperkalemia is a spuriously high serum potassium measurement in a patient with no clinical evidence of hyperkalemia. It has been reported to occur in patients with leukocytosis and thrombocytosis. Only a few cases of pseudohyperkalemia have been reported in patients after splenectomy. Two cases of pseudohyperkalemia occurring after emergency splenectomy for abdominal trauma are presented to highlight their clinical presentation and sequalae. Consecutive patients who underwent emergency splenectomy for trauma and subsequently developed pseudohyperkalemia were monitored in Universiti Kebangsaan Malaysia Medical Centre for their clinical sequalae. Both the patients developed leukocytosis, thrombocytosis and high serum potassium level within 2-weeks of their splenectomies. They did not demonstrate any symptoms and signs of hyperkalemia. Their conditions resolved spontaneously without any specific treatment. Pseudohyperkalemia should be suspected in a similar clinical scenario to avoid unnecessary treatment that could lead to severe hypokalemia.

Nephrectomy for a Case of Intrarenal Dermoid Cyst: Was it an Appropriate Decision?

Dermoid cyst in a kidney is rarely seen. We report a case of intrarenal dermoid cyst which mimics malignant renal tumour and discuss the dilemma in managing this disease.

Prevalence and Awareness of Lower Urinary Tract Symptoms among Males in the Outpatient Clinics of Universiti Kebangsaan Malaysia Medical Centre

This study aims to determine the prevalence of lower urinary tract symptoms (LUTS) and level of awareness among male outpatients in Universiti Kebangsaan Malaysia Medical Centre (UKMMC). A questionnaire consisting of demographic data, questions related to knowledge, attitude and practice on BPH and the International Prostate Symptom Score (IPSS) was used for this study. Uroflowmetry and bladder scan were used to evaluate the function of the urinary tract and severity of BPH. Urine dipstick was done for glycosuria, proteinuria and haematuria. A total of 220 respondents were surveyed. The prevalence of moderately and severely symptomatic LUTS was 42.7%. The most commonly reported LUTS were nocturia (78.2%), frequency (58.2%) and incomplete emptying (44.6%). The prevalence of glycosuria, proteinuria and haematuria were 23.6%, 11.4% and 1.8% respectively. There was a significant association between increasing age with the severity of LUTS (p=0.005). Out of 102 respondents with voided urine volume greater than 150 mL, there was a significant decrease in maximum (Qmax) (p=0.039) and average (Qave) urine flow rates with every 10 years increase of age (p=0.001). The majority of respondents (59.5%) have heard of BPH before. Over 78.2% of the respondents would seek medical attention if they have LUTS with 15.9% saying they would seek traditional treatment. In conclusion, the prevalence of LUTS was high and the level of awareness was satisfactory.

Strategy for generating tissue-engineered human bone construct

The strategy used to generate tissue-engineered bone construct, in view of future clinical application is presented here. Osteoprogenitor cells from periosteum of consenting scoliosis patients were isolated. Growth factors viz TGF-B2, bFGF and IGF-1 were used in concert to increase cell proliferation during in vitro cell expansion. Porous tricalcium phosphate (TCP)-hydroxyapatite (HA) scaffold was used as the scaffold to form 3D bone construct. We found that the addition of growth factors, greatly increased cell growth by 2 to 7 fold. TCP/HA proved to be the ideal scaffold for cell attachment and proliferation. Hence, this model will be further carried out on animal trial.

The use of bone marrow stem cells for bone tissue engineering

Bone marrow stem cells (BMSC), known for its multipotency to differentiate into various mesenchymal cells such as chodrocyte, osteoblasts, adipocytes, etc, have been actively applied in tissue engineering. BMSC have been successfully isolated from bone marrow aspirate and bone marrow scraping from patients of various ages (13-56 years) with as little as 2ml to 5ml aspirate. BMSC isolated from our laboratory showed the presence of a heterogenous population that showed varying prevalence of surface antigens and the presence of telomerase activity albeit weak. Upon osteogenic induction, alkaline phosphatase activity and mineralization activity were observed.
