ABSTRACT

Background Fungal keratitis has a high incidence in China and its clinical treatment is very difficult,and its etiology diagnosis and appraisal is the premise to improve the prognosis of disease.With the changes of regional environment and climate in recent years,whether the spectrum of fungal keratitis change in South China is remarkable.Objective The purpose of this study was to investigate recent pathogenic distribution of fungal keratitis in South China area.Methods The consecutive fungal culture resuhs of 3 350 purulent keratitis at Zhongshan Ophthalmic Center from January 2009 to December 2014 were retrospectively reviewed.The positive rate of fungal culture,genus or species distribution,seasonal distribution and different term distribution were analyzed.Results The culture-positive rate was 31.34% in this study (1 050/3 350),and the average culture-positive number was 175 strains per year.In the positive fungus,the highest positive rate was Fusarium SP (32.10%,337/1 050),and followed by Aspergillus SP (25.71%,270/1 050),Heminthosporium SP (14.29 %,150/1 050) and Mucor SP (9.14%,96/1 050).The fungal culture-positive rate was 36.05% (367/1 018) in 2009 to 2010,32.45% (324/1 014) in 2011 to 2012,and 26.86% (354/1 318) in 2013 to 2014,respectively,with a significant difference among the three periods (x2 =22.37,P<0.01),showing a decreasing tendency of incidence.Two hundreds and sixtyone strains were isolated from January to March (31.15 %,261/838),182 strains from April to June (25.53 %,182/713),237 strains from July to September (30.00%,237/790),370 strains from October to December (36.67%,370/1 009),showing a statistically significant difference among them (x2 =25.19,P < 0.01).The number of infectious strains was most during October to December and fewest during April to June.Conclusions The leading pathogenic fungi of fungal keratitis is Fusarium SP and followed by Aspergillus SP,Helminthosporium SP,Mucor SP in turn.Fungal keratitis is usually prevalent from October to December,and its incidence is still rising in Chinese mainland recently.However,the increasing tendency in South China has been prevented in recent six years.

ABSTRACT

Objective To evaluate the safety and effectiveness of endourological techniques in the treatment of benign prostate hyperplasia (BPH) in elderly high-risk patients.Methods A total of 202 BHP patients over 70 years old were treated with endourological techniques and followed up for 3-24 months.Patients were divided into transurethral resection of the prostate(TURP) group (n=90)and transurethral plasmakinetic resection of the prostate(PKRP) group (n =112).Results Compared with pre-treatment,the scores of IPSS and quality of life (QOL),residual urine volume and Qmax were improved in the TURP group after treatment [(6.3±1.2) vs.(27.8±2.5),(1.0±0.4)vs.(5.5±1.1),(18.0±2.8) ml vs.(95.0±18.0) ml,(17.5±1.4) ml/s vs.(5.4±2.0) ml/s,respectively,all P<0.05].Compared with before treatment,the scores of IPSS and QOL,residual urine volume and Qmax were also improved in the PKRP group after treatment [(8.4 ± 2.5) vs.(27.9±2.3),(1.0±0.4) vs.(1.5±0.5),(25±4) mlvs.(150±26) ml,(19±2.3) ml/svs.(7.0±2.3) ml/s,respectively,all P<0.05].There were no significant differences in IPSS,QOL,Qmax and RUV between the two groups after treatment (P>0.05),but the complication incidence was less in PKRP group than in TURP group (6.25% vs.22.2%,x2 =10.99,P<0.05).Conclusions PKRP is a safe and effective therapy for elderly high risk patients with BPH.The individual treatment,intensive monitoring and adjustment before operation,and skilled manipulation are the key points to the successful operation.

ABSTRACT

Objective To evaluate the efficacy of ureteroscopic pneumatic lithotripsy in the treatment of ureter stones.Methods A total of 186 cases ureteroscopic pneumatic lithotripsy were performed in our hospital.The outcomes of the surgery were analyzed.Results The success rate of the operation was 80.6%(29/36) for the upper ureteral calculi,92.7%(51/55) for the middle,and 100%(95/95) for the lower ones,respectively.Four weeks after the surgery,re-examination showed that the rate of stone removal was 94.1%(175/186).Injuries to the ureter occurred in 5(2.7%) of the cases.Conclusion Ureteroscopic pneumatic lithotripsy is an effective and safe method for ureteral calculi.

ABSTRACT

Objective To discuss the technique and therapeutic effect of pneumatic ballistic lithotripsy for the treatment of bladder calculi under ureteroscope via the outer sheath of resectoscope.MethodsTotally 42 patients with bladder calculi(39 men and 3 women)were treated in our hospital form March 2002 to February 2005.Among the patients,20 cases were complicated with BPH,and 3 had bladder fabrosis.The cystolith was crushed with pneumatic ballistic lithotripsy under an ureteroscope via the outer sheath of resectoscope.For the patients complicated with BPH(20 cases),prostatectomy was performed at the same time.ResultsAll the cases were cured in one session.No massive hemorrhage,bladder perforation,or overhydration occurred after the operation in this series.The patients were followed up for 6 to 18 months(mean 8 months),during which no recurrent cases were found,all the patients had normal urination.ConclusionsPneumatic ballistic lithotripsy via the outer sheath of resectoscope is an effective,simple,accurate method for the treatment of bladder stones.The procedure is superior in less complications and good outcomes.
