OBJECTIVE To find out the epidemiology of Salmonella aberdeen outbreaks in NICU and the ways to preventing and treating this nosocomial infection. METHODS The 22 cases who developed S.aberdeen in NICU from Mar 26 to Apr 20 2007 were studied prospectively to find out the reasons of the epidemic and treatment s based on the fecal sample culture results. RESULTS These 22 inpatients fecal samples cultures were tested positive for S.aberdeen,but 14 of 22 inpatients were developed infectious diarrhea. CONCLUSIONS S.aberdeen is confirmed as the cause to this infectious diarrhea outbreak,which is mainly transmitted by close contacts.The occurrence of infection outbreak can be reduced or controlled by emphasizing the hands hygiene and aseptic operation of medical workers,attaching importance to surface disinfection of environment and equipments,and establishing the early warning mechanism.

Objective To analyze the incidence of hospital-acquired infection and the distribution of pathogens through data from the hospital infection surveillance networks in Shandong. Methods A meta-analysis was made of the data submitted by the hospitals involved in the provincial surveillance networks from August 2001 to July 2004. Results The surveillance data involved 1 776 030 hospitalized patients, of whom 43 355 had a hospital-acquired infection, the incidence of hospital-acquired infection being 2.44‰. Respiratory-tract infections were most frequent, followed by gastroenteric-tract infections, urinary-tract infections and surgical-site infections. A total of 6 251 strains of pathogens were isolated, the most commonly identified pathogens being Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, Klebsiella pneumoniae, Candida albicans and Staphylococcus epidermidis. Conclusion It is imperative to reinforce the sterilization of air and medical instruments, strictly abide by aseptic manipulation, and promote the rational use of antimicrobials. Hospital infection surveillance ought to be conducted by the combined method of prevalence surveys and the targeted surveillance of key sectors.

OBJECTIVETo explore the therapeutic efficacy of a modified method with splints in correction of cryptotia.

METHODSFrom Oct. 2012 to Jan. 2014, 3 cases with unilateral cryptotia were treated with the modified method with splints. The muscles attached to the periosteum of cartilage were dissected. The muscles between the ear and temper were cut off. Then one silicon tube was put around the ear through cranioauricular sulcus. The other tube was placed within the cavum conchae and fixed with the tube around the ear.

RESULTSNo flap necrosis happened. The patients were followed up for six months to one year with satisfied and stable results.

CONCLUSIONSThe modified method is easy to perform with less morbidity. It is one of the ideal correction for cryptotia.

OBJECTIVE To study the effect of different antibiotic and nursing care in the treatment of patients with malignant tumor complicating with infection,analyze the high-risk factors and provide the dependable basis for controlling infection in hospital.METHODS In the retrospective investigation of our department,there were 82 times of 68 patients complicating with infection from Jan 2006 to Jun 2007.We analyzed the constituent proportion of infection and risk factors.The patients were divided into 4 groups,group A treated with broad-spectrum antibiotic,group B treated with narrow-spectrum antibiotic,group C treated with de-escalation therapy and group D treated with escalation therapy.We observed the course of therapy and the clinical effect.RESULTS The respiratory tract infection was 68.29%(56/82)and it was the highest one.The difference between groups C and D was significantly in susceptible factors(P

Objective To investigate the safety and feasibility of minimally invasive stealth lateral release operation in the treatment of chronic anal fissure . Methods Clinical data of 42 patients with chronic anal fissure who underwent minimally invasive stealth lateral release from May 2012 to May 2014 was analyzed retrospectively .We use the homemade fine steel wire to pierce into the sphincter ditch with a distance from the anus of 1 cm, and put the steel wire out above the dentate line .Then the wire was took out from the other edge under the skin through the needle of bobbin .After the needle was fixed by an assistant , the free end of the steel wire was pulled quickly to cut the internal sphincter tissue instantly . Results All the 42 patients were successfully treated and discharged without complications .The recovery time was in 7 -14 d, with an average of 9 d.The healing standards included disappeared symptoms and totally healed wound .All the patients were followed up for 3-6 months, with an average of 4 months.No recurrence was found . Conclusion Minimally invasive stealth lateral release in the treatment of chronic anal fissure is safe and feasible, with many advantages such as simple performance , reliable curative effect, fast recovery time, and less postoperative complications .

Objective To investigate the therapeutic effect on ulcerative colitis by methods of reinforcing qi,strengthing spleen and clearing heat antitoxicant. Methods 99 patients were divided into two groups randomly:the treatment group for oral and enteroclyste use with TCM following in the principle mentioned above,the control group for oral and enteroclyste use with western medicine following in the common practice. Comparative studies on the total therapeutic effect and the improvement of TCM syndromes between the two groups were made. Meanwhile,the Pearson correlation analysis were made to explore the relationship between the clinical effectiveness and impact factors in two groups. Results There were significant differences in the total curative effect and the improvement of TCM syndromes between two groups (P

OBJECTIVE To investigate the trends of susceptibility of Staphylococcus isolates to antimicrobial agents analyzed by the Shandong provincial nosocomial infection surveillance system.METHODS The data from Jan 2002 to Dec 2005 were summarized and analyzed by the Shandong provincial nosocomial infection surveillance system.RESULTS During this period,1644 strains of first isolate from each patient were collected.Major specimens were sputum,wounds,skin soft tissue and urine,which were 39.72%,22.08%,9.43% and 7.54% in total specimens,respectively.The drug-resistant rates of Staphylococcus isolates to antimicrobials were high,except to vancomycin.CONCLUSIONS Antimicrobial resistance of clinical isolates threatens the success of infectious disease treatment.It is very important to promote the rational use of antimicrobial agents for control of resistance and to take effective measures for the prevention of infections.

OBJECTIVE To investigate the trends of susceptibility of Enterobacter cloacae isolates to antimicrobial agents from Shandong provincial nosocomial infection surveillance system. METHODS The data from Shandong provincial nosocomial infection surveillance system from Aug 2001 to Jul 2004 were summarized and analyzed.(RESULTS) In the period of study from Aug 2002 to Jul 2004,231 strains of E.cloacae were collected.The (sputum),(urine) and wounds were major specimens,and accounted for 55.41%, 10.82% and 9.96% from total(specimens),respectively.The resistant rates of E.cloacae isolates to antimicrobials,except imipenem,increased to some extend.CONCLUSIONS Antimicrobial resistance of clinical isolates of E.cloacae threatens the success of(infectious) disease treatment.It is very important to promote the rational use of antimicrobial agents for control of resistance and to take effective measures for the prevention of infections.

OBJECTIVE To find out epidemiological features of fulminant Acinetobacter baumannii nosocomial infection in cardiac SICU and the ways to prevent and treat this nosocomial infection. METHODS The case histories from 5 inpatients who developed A.baumannii nosocomial infection in cardiac SICU from July 8 to 26,2004 were studied retrospectively to find out the reasons of the epidemia and treatments based on the sputum culture results. RESULTS These 5 inpatients developed lower respiratory tract infection on top of their original severe disease.Within 15 days,their sputum cultures were positive for A.baumannii,4 of them recovered but one died. CONCLUSIONS The inpatients got the same nosocomial infection within the same period because of lowered resistance owing to unreasonable layout of cardiac SICU,their original weakness is due to various invasive operation like long duration mechanical ventilation,lack of isolation and sterilization,etc.
