    With maturing functional and oncologic outcomes data, open partial nephrectomy (OPN) has become the standard of care for T1a renal tumor. Laparoscopic approach can provide a speedier recovery with less blood loss and postoperative pain. Presuming adequate laparoscopic expertise, laparoscopic partial nephrectomy can provide equivalent oncologic outcome as for OPN albeit with higher urologic complications rate and longer warm ischemia time. With refinement of technique and use of robotic assistant, the shortcomings of laparoscopic approach can be further reduced. This article is a mini-review on the current status of laparoscopic approach to partial nephrectomy in the management of small renal mass.

    OBJECTIVES: To evaluate the performance and utility of a time-temperature indicator (TTI) to determine the cumulative exposure time (CET) of red cell components (RCC) to temperatures above 10°C occurring within and outside the transfusion laboratory.

    BACKGROUND AND OBJECTIVES: Blood centres often use the '30 or 60-min rule' for accepting RCC exposed to room temperature (RT) back into inventory. Effective monitoring of these temperature deviations is however lacking.

    MATERIALS AND METHODS: A Timestrip PLUS® TP153 10°C (TS + 10) TTI was attached to RCC units after preparation of the unit in the blood bank or on issue to the ward, to track the CET > 10°C during laboratory processing and outside the transfusion laboratory.

    RESULTS: The mean CET of 153 RCC tracked within the laboratory was 56 min. Sixty-four (41.8%) and 34 (22.2%) of RCC had core temperature (CT) >10°C for more than 30 and 60 min, respectively. Among the 69 RCC that were returned unused, 27 (39.1%), 17 (24.6%) and 5 (7.2%) RCC units had CT >10°C for more than 30, 60 and 120 min respectively.

    CONCLUSION: A large proportion of RCC have CT >10°C exceeding 30 min during handling within the transfusion laboratory, as well as when RCC are returned unused from transfusion locations. Corrective measures should be implemented to better manage the cold chain to avoid undesirable consequences to blood transfusion. A temperature sensitive device that can also indicate CET can be employed to objectively monitor the period that RCC remained at a CT that exceeds 10°C.

    We present a rare case of leiomyoma of the urinary bladder that was diagnosed during pregnancy. The case of a 29-year-old woman primigravida at 13 weeks of pregnancy who presented with 6 months history of abdominal swelling which was gradually increasing in size. Computed tomography done revealed a large heterogenous mass(enhancing) with an area of non-enhancing (necrosis) suggestive of malignant ovarian tumor. The histological findings of the surgical specimen confirmed a leiomyoma of the urinary bladder. The clinical presentation, imaging findings, and management of this relatively rare benign tumor are discussed in this case report.

    INTRODUCTION: Majority of Wilms tumour (WT) responds well to pre-operative chemotherapy. In Malaysia, incidence of WT is rare with only two cases reported per one million populations yearly. This case report is to highlight on the awareness of WT in an Asian population and highlight two cases and challenges faced after pre-operative chemotherapy.

    CASE REPORT: In this case series, we report on two cases of WT which had poor response to pre-operative chemotherapy. Both cases underwent surgery after pre-operative chemotherapy and recovery was uneventful during a two-year follow-up.

    DISCUSSION: Both patients had chemotherapy prior planned surgery, but had unfortunate poor tumour response. The tumour progressed in size which required a radical nephrectomy. The histology report for the first case had more than 60% blastemal cells remaining despite giving pre-operative chemotherapy with no focal anaplasia. This showed poor response to chemotherapy evidenced by the high number of blastemal cells. The second case was a stromal type WT which is known for poor response and may lead to enhancement of growth and maturation induced by chemotherapy. These were the possible reason of poor response of WT in these two cases.

    Numerous immunohistochemical (IHC) biomarkers have been employed to aid in the difficult differentiation between chromophobe renal cell carcinoma (chRCC) and renal oncocytoma (RO). A systematic review and meta-analysis of the published literature was carried out to summarise and analyse the evidence for discriminatory IHC biomarkers to differentiate the two entities.

    PURPOSE: The COVID-19 pandemic has led to the cancellation or deferment of many elective cancer surgeries. We performed a systematic review on the oncological effects of delayed surgery for patients with localised or metastatic renal cell carcinoma (RCC) in the targeted therapy (TT) era.

    METHOD: The protocol of this review is registered on PROSPERO(CRD42020190882). A comprehensive literature search was performed on Medline, Embase and Cochrane CENTRAL using MeSH terms and keywords for randomised controlled trials and observational studies on the topic. Risks of biases were assessed using the Cochrane RoB tool and the Newcastle-Ottawa Scale. For localised RCC, immediate surgery [including partial nephrectomy (PN) and radical nephrectomy (RN)] and delayed surgery [including active surveillance (AS) and delayed intervention (DI)] were compared. For metastatic RCC, upfront versus deferred cytoreductive nephrectomy (CN) were compared.

    RESULTS: Eleven studies were included for quantitative analysis. Delayed surgery was significantly associated with worse cancer-specific survival (HR 1.67, 95% CI 1.23-2.27, p

    Metastatic renal cell carcinoma (RCC) presenting with multiple deposits in the head and neck region is unusual. It is not uncommon for a RCC to metastasise to a distant site after years of a tumour-free period, but most of it would be expected to have a single site of deposit. We report a rare case of a patient who had a nephrectomy 10 years earlier for RCC and presented with tumours in the frontal sinus and posterior pharyngeal wall. Radiological imaging and histology confirmed metastatic RCC at both sites.

    Context: Metabolic imbalance in renal cell carcinoma (RCC) can lead to abnormal adiponectin levels. Objective: To evaluate circulating adiponectin as a detection or predictive marker for RCC. Methods: A comprehensive literature search and meta-analysis was performed on studies reporting circulating adiponectin levels and RCC. The meta-analysis was performed using RevMan. Results: Seven studies compared the circulating adiponection levels between RCC cases and controls. Adiponectin level was significantly lower in RCC cases compared to controls at pre-diagnosis and pre-operative time-points. RCC stage, grade and subtype did not affect adiponectin levels. Conclusion: Low circulating adiponectin could be a predictive or risk factor for RCC.

    Angiomyolipomas are rare tumours of the kidney which have a tendency to bleed. We studied the clinical and radiological features of 11 patients from our institution to identify features which may be predictive of a massive haemorrhage. Tumours more than 6 cm in diameter were found to bleed and the demonstration of pseudoaneurysms on contrast CT scanning was associated with massive haemorrhage. We conclude that large angiomyolipomas should be treated to avoid haemorrhage and the detection of pseudoaneurysms should prompt urgent treatment.

    Five cases of renal angiomyolipoma which underwent spontaneous rupture are described. These patients presented as an "acute abdomen" for which the diagnosis was not initially apparent. A high index of suspicion is required to make the diagnosis even with modern imaging techniques. The treatment of these tumours is discussed.

    The propensity of choriocarcinoma to metastasize to lungs, liver and brain is well known. Though theoretically metastases are possible to anywhere in the body, renal metastases are rare. A 56 year old Malay woman who had total abdominal hysterectomy in 1985 for molar pregnancy presented with haemoptysis and dyspnea in 1990. Examination showed she had choriocarcinoma with pulmonary and renal metastases.

    INTRODUCTION: Laparoscopic nephrectomy is the standard of care for the removal of both non-functioning and tumourbearing kidneys. This study was conducted to compare the characteristics and outcomes follow-ing laparoscopic transperitoneal nephrectomy (TP) for tumour and nontumour disease.

    METHODS: We retro-spectively reviewed all TP nephrectomies performed in the Hospital Sultanah Bahiyah Alor Setar, Kedah between January 2016 and July 2017.

    RESULTS: A total of 36 eligible cases were identified, 10 of which were for renal tumours and the others for nonfunctioning kidneys. There were no statistically significant differ-ences between the two groups in terms of demographics and comorbidities. We also did not identify any sta-tistically significant differences between the two groups in terms of operating time, blood loss, need for transfusion, septic complications and postoperative recovery. The only significant difference between the groups was the postoperative rise in serum creatinine, which was higher in the tumour disease group (mean rise 23.4 vs 5.35µmol/l; p = 0.012).

    CONCLUSIONS: Our study showed that laparoscopic nephrectomy is both feasible and safe for the treatment of tumour and non-tumour renal disease with low complication rates in both groups.

    Melatonin is a serotonin-derived pineal gland hormone with many biological functions like regulating the sleep-wake cycle, circadian rhythm, menstrual cycle, aging, immunity, and antioxidants. Melatonin synthesis and release are more pronounced during the night, whereas exposure to light decreases it. Evidence is mounting in favor of the therapeutic effects of melatonin in cancer prevention, treatment and delayed onset in various cancer subtypes. Melatonin exerts its anticancer effect through modification of its receptors such as melatonin 1 (MT1), melatonin 2 (MT2), and inhibition of cancer cell proliferation, epigenetic alterations (DNA methylation/demethylation, histone acetylation/deacetylation), metastasis, angiogenesis, altered cellular energetics, and immune evasion. Melatonin performs a significant function in immune modulation and enhances innate and cellular immunity. In addition, melatonin has a remarkable impact on epigenetic modulation of gene expression and alters the transcription of genes. As an adjuvant to cancer therapies, it acts by decreasing the side effects and boosting the therapeutic effects of chemotherapy. Since current treatments produce drug-induced unwanted toxicities and side effects, they require alternate therapies. A recent review article attempts to summarize the mechanistic perspective of melatonin in different cancer subtypes like skin cancer, breast cancer, hepatic cancer, renal cell cancer, non-small cell lung cancer (NSCLC), colon oral, neck, and head cancer. The various studies described in this review will give a firm basis for the future evolution of anticancer drugs.

    Oral sodium phosphate (OSP), an effective bowel purgative, is available over the counter (OTC) and requires a substantially lower volume than polyethylene glycol-based preparative agents. Rarely, OSP consumption has been associated with acute hypocalcemia and hyperphosphatemia. We describe a case of chronic kidney disease patient developing symptomatic hypocalcemia following OTC OSP.
