Objective: This study was to assess liver involvement in multiple myeloma with the aid of liver function tests. Materials and Methods: A hospital based retrospective study was undertaken using data retrieved of multiple myeloma from the register maintained in the Department of Biochemistry of the Manipal Teaching Hospital, Pokhara, Nepal between $1^{st}$ January, 2007 and $28^{th}$ February, 2012. We collected biomarkers of liver profiles including bilirubin (Total, Direct and Indirect), total protein, albumin, AG ratio, SGOT, SGPT, ALP, ${\gamma}GT$, LDH, ferritin, renal profile and hematological profile. Descriptive statistics and testing of hypothesis were used for the analysis using EPI INFO and SPSS 16 software. Results: Out of 37 cases of multiple myeloma, serum level of AST, ALT, ALP, ${\gamma}GT$ and LDH were increased above the cut-off point in 22 (59.5%), 24 (64.86%), 13 (35.13%), 9 (24.3%) and 11 (29.7%) respectively. The mean values of AST ($65.5{\pm}28.18$ U/L), ALT ($68.37{\pm}29.74$ U/L), ALP ($328.0{\pm}148.4$ U/L), ${\gamma}GT$ ($44.5{\pm}29.6$ U/L) and LDH ($361.7{\pm}116.5$ U/L), total protein ($9.79{\pm}1.03$ gm/dl) were significantly increased when compared with controls. In contrast, albumin ($3.68{\pm}0.43$ gm/dl) and the AG ratio ($0.62{\pm}0.15$) were significantly decreased. Similarly, anemia, hyperuricemia, azotemia, hypercalcaemia and Bence Jones proteinuria were found in 30 (78.9%), 27 (71.1%), 19 (51.5%), 15 (39.5%) and 16 (42.1%) respectively, in cases of multiple myeloma. Conclusions: While clinical manifestation of liver disease among the multiple myeloma was not common, abnormalities in liver function were characteristic.

Autosomal dominant polycystic kidney disease (ADPKD) is a common genetic disorder characterized by the formation of fluid-filled cysts in the kidney and progressive renal failure. Other manifestations of ADPKD include the formation of cysts in other organs (liver, pancreas, and spleen), hypertension, cardiac defects, and cerebral aneurysms. The loss of function of the polycystin -1 and -2 results in the formation of epithelium-lined cysts, a process that depends on initial epithelial proliferation. cDNA microarrays powerfully monitor gene expression and have led to the discoveries of pathways regulating complex biological processes. We undertook to profile the gene expression patterns of epithelial cells derived from the cysts of ADPKD patients using the cDNA microarray technique. Candidate genes that were differently expressed in cyst tissues were identified. 19 genes were up-regulated, and 6 down-regulated. Semi-quantitative RT-PCR results were consistent with the microarray findings. To distinguish between normal and epithelial cells, we used the hierarchical method. The results obtained may provide a molecular basis for understanding the biological meaning of cytogenesis.

Gadolinium contrast agents (CAs) are integral components of clinical magnetic resonance imaging (MRI). However, safety concerns have arisen regarding the use of gadolinium CAs, due to their association with nephrogenic systemic fibrosis (NSF). Furthermore, recently the long-term retention of $Gd^{3+}-based$ CAs in brains patients with normal renal function raised another possible safety issue. The safety concerns of $Gd^{3+}-based$ CAs have been based on the ligand structure of $Gd^{3+}-based$ CAs, and findings that $Gd^{3+}-based$ CAs with linear ligand structures showed much higher incidences of NSF and brain retention of CAs than $Gd^{3+}-based$ CAs with macrocyclic ligand structure. In the current study, we report the in vivo biodistribution profile of a new highly stable multifunctional $Gd^{3+}-based$ CA, with macrocyclic ligand structure (HNP-2006). MR imaging using HNP-2006 demonstrated a significant contrast enhancement in many different organs. Furthermore, the contrast enhanced tumor imaging using HNP-2006 confirmed that this new macrocyclic CA can be used for detecting tumor in the central nervous system. Therefore, this new multifunctional HNP-2006 with macrocyclic ligand structure shows great promise for whole-body clinical application.

Background: Multiple myeloma is the most common malignant plasma cell dyscrasia and ranks second among primary haematological malignancies. This study describes the epidemiologic, clinical and pathologic profile of monoclonal gammopathies seen in the University Hospital of the West Indies (UHWI), a tertiary care referral centre. Materials and Method: A retrospective analysis of 85 cases diagnosed at UHWI over the 5-year period 2003-2007 was conducted. The cases were identified from the bone marrow records as well as the computerized database of the Medical Records Department. Clinical presentation, family and personal history and demographic data were retrieved. Haematological and biochemical results were also analyzed. Results: There were 85 patients diagnosed with monoclonal gammopathies. The M:F ratio was 1.2:1 and the mean age was $65.7{\pm}1.3$ years. Eighty percent of the patients had skeletal pain and 40% experienced weight loss. Of the patients experiencing bone pain 56.7% had multiple lytic lesions, 26.7% had pathological fractures and 26.7% had compression fractures. Seventy-four patients (87.1%) had a haemoglobin level <12.0 g/dL with 52.9% having values <8.0 g/dL. Renal impairment was evident at diagnosis in 36.5%. Hypercalcemia was seen in 26.5% and hyperuricemia in 45.9%. Of the 79 patients who had serum protein electrophoresis performed, 77.2% had at least one monoclonal band and of these 24.6% had a monoclonal protein also present on urine protein electrophoresis. Conclusions: The demographic profile in this group of patients is largely similar to other studies in predominantly Caucasian populations; however there was a notable increase in prevalence of severe disease at presentation, with the majority of patients presenting at the most advanced stage. It is probable that these differences reflect socioeconomic factors and not merely inherent ethnic variation in disease biology.

Since the advent of growth hormone(GH), children with a wide variety of growth disorders have received GH treatment. In GH deficiency(GHD), Turner syndrome, chronic renal failure, children born small for gestational age, Prader-Willi syndrome, and idiopathic short stature, the therapeutic effects and safety profile of GH are reviewed. GH therapy has been clearly shown to improve height velocity and final adult height in a variety of pediatric conditions in which growth is compromised irrespective of GHD. Early initiation and individualization of GH treatment has the potential to normalize childhood growth. The supra-physiological doses of GH have been shown to increase height velocity during childhood and final height in non-GHD conditions. Adverse events during GH therapy are uncommon and often not drug related. However continued surveillance into adult life is crucial, especially in children receiving supra-physiological doses or whose underlying condition increases their risk of adverse effects.

Valaciclovir is metabolized to acyclovir after ingestion and thereafter exerts its antiviral activity. Because of its superior pharmacokinetic profile, it has quickly replaced acyclovir in the treatment of herpesvirus infection. Neurotoxicity caused by valaciclovir has been reported, however, among patients with pre-existing impaired renal function. This paper reports a case of neurotoxicity of valaciclovir in a patient with end-stage renal disease who was undergoing continuous ambulatory peritoneal dialysis (CAPD). A 67-year-old female on CAPD took 500 mg of valaciclovir twice for herpes zoster. After she took her second dose orally, she developed confusion and disorientation, along with involuntary movements. Her mental confusion progressed to a coma. Discontinuation of valaciclovir showed no rapid improvement. There- fore, hemodialysis was started. After two sessions of hemodialysis, the patient became alert; and after four sessions of hemodialysis, her neurological abnormalities were completely reversed. In conclusion, valaciclovir can induce life-threatening neurotoxicity, especially in CAPD patients, even with appropriate dose reduction, which can be effectively managed by hemodialysis.

목 적: 국소성 분절성 사구체 경화증(Focal segmental glomerulosclerosis, 이하 FSGS)은 소아신부전의 원인 중 가장 흔한 사구체 질환이다. 일차성 FSGS의 병인은 아직 알려져 있지 않으므로, 저자들은 FSGS의 동물 모델을 대상으로 cDNA 마이크로어레이를 이용한 유전자 발현 양상 분석을 통하여 유전자 발현 수준에서의 FSGS의 질환의 특성을 밝히고자 하였다. 방 법: 사람의 일차성 FSGS와 유사한 질병경과를 보이는 동물모델인 FGS/kist 생쥐의 신피질 조직을 대조군 생쥐(FGS/kist 생쥐의 조상 strain인 RFM/kist 생쥐)와 AB 1700 mouse chip을 이용한 마이크로어레이 실험으로 비교하였다. 결 과: FGS 질병특이 유전자가 62개 추출되었다. 이들은 세포주기/사멸, 면역반응과 지질 대사/혈관 질환과 관련된 유전자들로써, 유전자간 network의 중심유전자가 면역반응(TNF, IL-6/4, IFNg)과 세포사멸 조절 유전자(TP 53), 그리고 지질대사의 중요 유전자인 PPARG이었다. 결 론: 이 연구에서 저자들은 자발적인 FSGS의 임상경과를 보이는 FGS/Kist 생쥐의 신장조직의 유전자 발현의 분석을 통하여 신장세포사멸과 면역반응에 뒤따르는 기질 섬유화, 그리고 지질 대사의 이상과 조기 혈관 질환이 FSGS의 병태생리에 기여할 것임을 다시 확인할 수 있었다. 추가적인 연구가 계속된다면 global transcriptome profiling 기법으로 병인 탐색 및 치료방법 개발 에 의미 있는 결과를 도출할 수 있을 것이다.
