Urinary bladder catheter encrustations are known complications of long-term urinary catheterisation, which is commonly seen in clinical practice. These encrustations can impede deflation of the balloon and therefore cause problems in the removal of the catheter. The options in managing an encrusted and incarcerated urinary bladder catheter include extracorporeal shock wave lithotripsy and lithoclast. We describe here another technique of dealing with a stuck and encrustated catheter, via direct crushing of the encrustations with a rigid cystoscope inserted through a suprapubic cystostomy tract.

Hand-assisted laparoscopic nephrectomy (HAL-N) and nephroureterectomy (HAL-NU) were introduced to bridge the gap between open and laparoscopic surgery. This newer technique has the benefits of both laparoscopic and open surgical approaches but has a shorter learning curve and decreased operative time compared to laparoscopic surgery. A review of our 2-year experience showed that for the seventeen cases of HAL-N that was performed, the mean operative time was 187.8 minutes while the mean length of hospital stay was 4.1 days. For the two HAL-NU cases, the mean operative time was 415 minutes while the mean length of hospital stay was 5.5 days. Only one complication occurred and it was an incisional hernia at the hand-port site. There was no recurrence for the carcinoma cases. Our experience shows that this technique is feasible and safe.

PMID: 17243535 MyJurnal

Distant haematogenous metastasis in penile cancer is rare. A patient who had total penectomy and bilateral inguinal lymphadenectomy for penile cancer but later presented with hypercalcemia of malignancy and pathological fracture of the humerus is reported.

Testicular mass: do not forget filariasis

Infection, 2013 Aug;41(4):893-6.

Parasite infestation of the testicular tunica and spermatic cord by filariae are rarely reported and may present with few clinical signs, depending upon the stage. Occasionally, it may mimic a testicular tumor. We present a case of a 29-year-old man who presented with left testicular swelling and discomfort for 4 months. Clinical examination and imaging suggested an intrascrotal cystic lesion with a normal left testis. However, the intraoperative findings revealed a tumor-like mass; hence, a left orchidectomy was performed. However, histopathology reported a diagnosis of a cystic testicular tunica and spermatic cord with parasite infection. Here, we review the literature of scrotal and testicular parasite disease and discuss the course of the appropriate management involved.

Electrokinetic Behavior of Palm Oil Emulsions in Dilute Electrolyte Solutions

Ho CC, Ahmad K

J Colloid Interface Sci, 1999 Aug 1;216(1):25-33.

PMID: 10395758

The effect of metal cations, both nonhydrolyzable and hydrolyzable, on the zeta potential of palm olein emulsions stabilized by the nonionic emulsifier, polyoxyethylene nonyl phenyl ether, was investigated as a function of pH and cation concentrations, respectively. The oil drops were found to be negatively charged in the presence of simple mono- and divalent cations. Charge reversal of the oil drops was observed when hydrolyzable cations (Zn2+, Cu2+, Fe3+, and Al3+) were used and the behavior is strongly dependent on the type of cation, its concentration, and the pH of the dispersion. The results are discussed in terms of current theories of electrophoresis and adsorption-precipitation at interfaces. The chemical free energies of adsorption of the cations were calculated.

PMID: 7219267

A case of pseudomyxoma peritonei is reported. Pathogenesis, clinical features and modes of treatment are discussed. This patient appears to have responded to laparotomy, paracentesis and instillation of cyclophosphamide intraperitoneally.

Fulltext Male sexual dysfunction in Asia

Ho CC, Singam P, Hong GE, Zainuddin ZM

Asian J Androl, 2011 Jul;13(4):537-42.

PMID: 21643001 DOI: 10.1038/aja.2010.135

Sex has always been a taboo subject in Asian society. However, over the past few years, awareness in the field of men's sexual health has improved, and interest in sexual health research has recently increased. The epidemiology and prevalence of erectile dysfunction, hypogonadism and premature ejaculation in Asia are similar in the West. However, several issues are specific to Asian males, including culture and beliefs, awareness, compliance and the availability of traditional/complementary medicine. In Asia, sexual medicine is still in its infancy, and a concerted effort from the government, relevant societies, physicians and the media is required to propel sexual medicine to the forefront of health care.

Treatment of the Hypogonadal Infertile Male-A Review

Ho CC, Tan HM

Sex Med Rev, 2013 May;1(1):42-49.

PMID: 27784559 DOI: 10.1002/smrj.4

INTRODUCTION: Testosterone treatment for hypogonadism is detrimental for men in reproductive age as it impairs spermatogenesis, and therefore affects fertility. It is, therefore, not indicated in men with hypogonadism and infertility.

AIM: The aim of this review is to analyze current data regarding options of treatment for men with hypogonadism and infertility.

MAIN OUTCOMES MEASURES: A comprehensive review of the current literature on management of infertility among hypogonadal men.

METHODS: A literature search using PubMed from 1980 to 2012 was done on articles published in the English language. The following medical subject heading terms were used: "infertility," "infertile," "hypogonadism;" "testosterone deficiency" and "men" or "male;" and "treatment" or "management."

RESULTS: The options for hypogonadal testicular failure are limited. Hormonal treatment is by and large ineffective. For secondary hypogonadism (hypogonadotropic/normogonadotropic hypogonadism), the options include gonadotropin-releasing hormone, human chorionic gonadotropin (hCG), human menopausal gonadotropin (hMG), follicle-stimulating hormone (FSH), and anti-estrogens and aromatase inhibitors. Dopamine antagonist is indicated for prolactinoma. Artificial reproductive technique is indicated for primary testicular failure and also when medical therapy fails.

CONCLUSION: The most suitable option with the current data available is hCG with or without hMG/FSH. Testosterone supplementation should be avoided, but if they are already on it, it is still possible for a return of normal sperm production within 1 year after discontinuing testosterone.

Fulltext Retrograde intrarenal surgery for renal stones smaller than 2 cm

Ho CC, Hafidzul J, Praveen S, Goh EH, Bong JJ, Lee BC, et al.

Singapore Med J, 2010 Jun;51(6):512-5.

PMID: 20658113

Extracorporeal shock wave lithotripsy (ESWL) is accepted as the gold standard treatment for renal stones that are smaller than 2 cm. Recently, retrograde intrarenal surgery (RIRS) has been introduced as another form of treatment. We report our experience in dealing with renal stones smaller than 2 cm using RIRS as the primary treatment and following failed ESWL.

Fulltext Alum irrigation for the treatment of intractable haematuria

Ho CC, Md Zainuddin Z

Malays J Med Sci, 2009 Oct;16(4):66-8.

PMID: 22135514 MyJurnal

Managing intractable haematuria is a daunting task. One cause of this condition is radiationinduced haemorrhagic cystitis. Several treatments for the condition have been proposed and one non-invasive option is alum irrigation. Here, we report on a 65-year-old woman with intractable haematuria secondary to radiation cystitis who was successfully treated with alum irrigation. Alum irrigation is safe, well tolerated and relatively cheap. A review of the literature and a comprehensive discussion on alum irrigation as treatment for haematuria is discussed here to create an awareness regarding this treatment option.

Fulltext Ketamine-associated ulcerative cystitis: a case report and literature review

PMID: 22135540 MyJurnal

Ketamine can be abused as a recreational drug, and there has been a recent surge in its usage. The effects of ketamine on the urinary system were unknown until the recent publication of a few case reports. Many doctors are still unaware of this new clinical entity, termed ketamine-associated ulcerative cystitis. We report a case that we encountered and discuss the diagnosis and disease management in addition to a review of the literature.
