Urodynamic studies in the evaluation of young men presenting with lower urinary tract symptoms

AIM: To evaluate the usefulness of urodynamic study in young men with lower urinary tract symptoms (LUTS). METHODS: We reviewed the charts of 50 men with LUTS aged 50 years and below. Those with neurological diseases, urethral trauma or strictures were excluded. All underwent multichannel urodynamic studies (UDS). The pre- and post-UDS diagnoses and treatment modalities were compared. RESULTS: Mean age was 38.1 years (17-49). The main pre-UDS diagnoses included prostatitis in seven (14%), overactive bladder in seventeen (34%) and benign prostatic hyperplasia in nine (18%). Pre-UDS management ranged from anticholingeric agents for thirteen (26%), alpha-adrenergic antagonists for nine (18%), antibiotics for six (12%). Abnormal UDS were noted in 36 (72%), including detrusor overactivity in 9 (18%), detrusor underactivity/acontractility in 5 (10%) and bladder outlet obstruction in 21 (42%). Fourteen (28%) had primary bladder neck dysfunction and five (10%) had benign prostatic hyperplasia. Post-UDS management included anticholingeric agents for ten (26%), alpha-adrenergic antagonists for seventeen (34%), catheterization for four (10%), behavioral therapy for three (6%), surgery for three (6%). None were prescribed antibiotics. Following UDS, the diagnosis had to be updated in 40 (80%) and concomitant change in management was required in 34 (68%). CONCLUSION: Young men presenting with LUTS have different underlying etiologies. Clinical diagnosis and treatment are often empiric and inaccurate. Urodynamic study is useful in the evaluation of this group of patients as it aids in arriving at an accurate diagnosis and guides treatment therapy.

Do children with primary nocturnal enuresis have a retarded bone age? A cross‐sectional study

OBJECTIVE: Nocturnal enuresis is a common pediatric problem, the etiology of which is unclear. In recent years, various studies have been published stating that children with nocturnal enuresis exhibit growth and skeletal maturation retardation. METHODS: In this cross-sectional study, we included 27 patients (16 boys, 11 girls) between the ages of 6 and 14 years who had presented with primary nocturnal enuresis (PNE) complaints. We included in the evaluation 19 healthy subjects (12 boys, 7 girls), who were the siblings of the children with PNE, as the control group. RESULTS: The patients in both groups were similar in chronological age, bone age, height and weight, with no significant difference between groups (P>0.05). CONCLUSION: The two groups in our study consisted of the same genetic background. Thus, our results were found to be different from the previous studies. We have concluded that there is no direct relationship between enuresis nocturnal and skeletal maturation.     

胎儿生长迟缓与新生儿胰岛素敏感性变化的相关性

目的探讨胎儿生长迟缓(FGR)与新生儿胰岛素敏感性变化的关系。 方法昆明医学院第一附属医院于2004年4~12月，对72例小于胎龄儿(SGA)和48例适于胎龄儿(AGA)空腹血糖(FPG)、空腹胰岛素(FINS)、C 肽、HDL C、LDL C、TG、非酯化脂肪酸(NEFA)等指标，计算葡萄糖/胰岛素比值(G/I)、胰岛素敏感性指数(ISI)、胰岛素抵抗指数(HOMA IR)、胰岛β细胞功能(HBCI)等，探讨FGR与新生儿胰岛素敏感性变化的关系。 结果(1)SGA组FPG、HDL C低于AGA组，而FINS、LDL C、TG、NEFA高于AGA组(P<001)；(2)SGA组G/I比值、ISI低于AGA组，HOMA IR高于AGA组(P<001)，而HBCI两组相比差异无显著性(P>005)。 结论FGR儿在生命早期存在胰岛素敏感性降低和不同程度的胰岛素抵抗(IR)，而胰岛β细胞功能无明显变化。     

Does the Extent of Surgery Make a Difference in High Grade Malignant Astrocytoma?

This paper examines the effect of patient age, tumour grade and extent of surgery on the outcome of treatment of 278 patients with high grade malignant gliomas referred to the Queensland Radium Institute between 1980 and 1987. The aim was to determine whether the extent of surgical resection alters survival rates. The extent of surgery had no effect on survival except for those patients with grade 3 tumours in whom a total excision was possible. Those in whom only a biopsy was done did not have a worse prognosis. Grading was found to be of importance, as patients with grade 3 tumours had a better survival than those with grade 4 tumours. In grade 4 tumours, those under 30 years of age had a better survival than those over 30 years, whereas with grade 3 tumours there was a gradation of age effect (under 40 years best, then 40–49 years, and those 50 years and over doing worst).     

Older donors and kidney transplantation

Reluctance to use kidneys from older donors (>50 years of age) is based on reports of inferior results. We reviewed our experience with 45 kidneys transplanted from older donors. Primary nonfunction, immediate graft function, and 1-, 2- and 3-year graft survival rates were similar to those obtained with kidneys transplanted from donors aged between 20 and 40 years. Renal function at 1 year (as measured by serum creatinine) was poorer in kidneys from older donors. No beneficial effect with respect to graft survival was noted with cyclosporin therapy compared to conventional immunosuppression; however, the numbers are small. We conclude that kidneys from older donors are a valuable source for transplantation.     

Angiodysplasia as the cause of massive lower gastrointestinal hemorrhage in a young adult

PURPOSE: This study was undertaken to clarify the importance of bleeding vascular ectasia of the colon as the etiology of massive lower gastrointestinal hemorrhage in patients 40 years of age or younger. METHODS: An otherwise healthy 21-year-old male was admitted to a tertiary medical center with massive lower gastrointestinal hemorrhage. Technetium-labeled red blood cell scan, selective visceral angiography, and colonoscopy identified the source of bleeding as vascular abnormality of the descending colon. Segmental colonic resection was performed. RESULTS: Histologic review of the specimen demonstrated a vascular ectasia. The patient recovered uneventfully and has had no further stigmata of hemorrhage. A review of the literature was undertaken to make clear the significance of vascular ectasia as the source for massive colonic hemorrhage in the young adult. CONCLUSION: This is the first report that documents histologically a vascular ectasia as the source of massive lower gastrointestinal hemorrhage in an otherwise healthy patient less than 40 years of age. Vascular ectasia is an uncommon cause of lower gastrointestinal hemorrhage in the young adult.The Chief, Bureau of Medicine and Surgery, Navy Department, Washington, DC, Clinical Investigation Program sponsored this report #84-16-1968-532, as required by HSETCINST 6000.41A.

The Treatment of Low Grade Cerebral Astrocytomas by Radiotherapy in Queensland

The records of 108 adult patients with supratentorial low grade astrocytoma presenting between 1/1/80 and 31/12/87 were examined for the following factors which might affect survival: patient age, extent of surgical resection, site of tumour, tumour grade, radiation field size and radiation dose. Univariate analysis showed that patient age, field size and radiation dose were significant prognostic factors, but with multivariate analysis only patient age and radiation field size were significant independent variables. It is possible that field size is a proxy variable for tumour size.
