Objective: To explore the clinical characteristics, common pathogens in children with vulvovaginitis. Methods: This was a retrospective cases study. A total of 3 268 children with vulvovaginitis were enrolled, who visited the Department of Pediatric and Adolescent Gynecology, Children's Hospital, Zhejiang University School of Medicine from January 2009 to December 2019. Patients were divided into 3 groups according to the age of <7, 7-<10 and 10-18 years. Patients were also divided in to 4 groups according to the season of first visit. The pathogen distribution characteristics of infective vulvovaginitis were compared between the groups. Their clinical data were collected and then analyzed by χ2 test. Results: The were 3 268 girls aged (6.2±2.5) years. There were 1 728 cases (52.9%) aged <7 years, 875 cases (26.8%) aged 7-<10 years, and 665 cases (20.3%) aged 10-18 years. Of these cases, 2 253 cases (68.9%) were bacterial vulvovaginitis, 715 cases (21.9%) were fungal vulvovaginitis and 300 cases (9.2%) were vulvovaginitis infected with other pathogens. Bacterial culture of vaginal secretions was performed in 2 287 cases, and 2 287 strains (70.0%) of pathogens were detected, of which the top 5 pathogens were Streptococcus pyogenes (745 strains, 32.6%), Haemophilus influenzae (717 strains, 31.4%), Escherichia coli (292 strains, 12.8%), Staphylococcus aureus (222 strains, 9.7%) and Klebsiella pneumoniae (67 strains, 2.9%). Regarding different age groups, H.influenzae was the most common in children under 7 years of age (40.3%, 509/1 263), S.pyogenes (41.9%, 356/849) was predominantly in children aged 7 to 10 years, and E.coli was predominant in children aged 10 to 18 years (26.3%, 46/175). Susceptibility results showed that S.pyogenes was susceptible to penicillin G (610/610, 100.0%), ceftriaxone (525/525, 100.0%), and vancomycin (610/610, 100.0%); the resistance rates to erythromycin and clindamycin were 91.9% (501/545)and 90.7% (495/546), respectively. For H.influenzae, 32.5% (161/496) produced β-elactamase, and all strains were sensitive to meropenem (489/489, 100.0%) and levofloxacin (388/388, 100.0%), while 40.5% (202/499) were resistant to ampicillin. Among E.coli, all strains were sensitive to imipenem(100%, 175/175). The resistance rates of E.coli to levofloxacin and ceftriaxone were 29.1% (43/148) and 35.1% (59/168), respectively. A total of 48 strains of methicillin-resistant Staphylococcus aureus (MRSA) were isolated with a proportion of 28.3% (45/159) in 3 268 patients. The results of drug susceptibility test showed that all MRSA strains were sensitive to linezolid 100.0% (40/40), vancomycin (45/45, 100.0%), and tigecycline (36/36, 100.0%); the resistance rates of MRSA to penicillin G, erythromycin and clindamycin were 100% (45/45), 95.6% (43/45) and 88.9% (40/45), respectively. All methicillin-sensitive Staphylococcus aureus (MSSA) strains were sensitive to oxacillin (114/114, 100.0%), linezolid (94/94, 100.0%), vancomycin (114/114, 100.0%), and tigecycline (84/84, 100.0%); it's resistance rates to penicillin G, erythromycin and clindamycin were 78.1% (89/114), 59.7% (68/114) and 46.5% (53/114), respectively. The drug resistance rate of MSSA to penicillin G, erythromycin and clindamycin were lower than those of MRSA (χ²=11.71,19.74,23.95, respectively, all P<0.001). Conclusions: The age of consultation for pediatric infectious vulvovaginitis is mainly around 6 years. The most common pathogens are S.pyogenes, H.influenzae and Escherichia coli. Third generation cephalosporins can be used as the first choice of empirical anti-infection drugs. However, the results of drug susceptibility should be considered for targeted treatment.

OBJECTIVETo investigate the effect of antibiotics on postoperative inflammatory complications after surgical extraction of the impacted mandibular third molar.
METHODSNinety-Six patients had their bilateral third molars removed through a split-mouth, double-blind, controlled, clinical trial in two visits. On one side amoxicillin (or clindamycin) was used (antibiotics group) from 1 h pre-operation to 3 d post-operation. On the other side, placebo was used (placebo group) the same time. Postoperative inflammatory complications including alveolar osteitis (AO), surgical site infection (SSI), pre-buccal site infection and anterior isthmus faucium space infection were monitored and recorded 2 d and 10 d after the surgery. The pain, swelling, and trismus were also recorded.
RESULTSAll 96 patients completed the study. Two AO (2.1%), one SSI (1.0%) and seven other infections were observed in the treatment group. Also three AO (3.1%), one SSI (1.0%) and eleven other infections were observed in the placebo group. However, no statistically significant differences were found in the incidence of various postoperative inflammatory complications and reactions between the groups (P > 0.05). There was no significant difference on the postoperative reaction, except pain on 10 d. Patients who had inflammatory infection recovered well with symptomatic anti-infection treatment.
CONCLUSIONSThe use of amoxicillin (or clindamycin) cannot effectively prevent and reduce the postoperative inflammatory complications after surgical extraction of the impacted mandibular third molar.

A 36-year old female with acute myelogenous leukemia presented with a sudden decrease in vision one month following bone marrow transplantation (BMT). She had been taking multiple immunosuppressants to treat her recently-developed graft-versus-host-disease (GVHD). Visual acuity was 20/60 in her right eye and 20/25 in her left. Ophthalmic examination revealed mild inflammatory reaction in both the anterior chamber and the vitreous of both eyes, as well as densely opaque yellow-white infiltrates with well-demarcated borders in the posterior retina of both eyes. She was originally diagnosed as CMV retinitis, but treatment with ganciclovir failed to improve her ocular condition. Subsequent work-up, including serology and brain MRI, led to a diagnosis of combined ocular and cerebral toxoplasmosis. After 6 weeks of antiparasitic therapy, her retinal lesions became inactive and her cerebral lesions improved. Immunosuppressed patients with necrotizing retinochoroiditis should be suspected of having toxoplasmosis. Accurate differentiation between this condition and CMV, and early intervention with the appropriate treatment may be critical to preserve the best vision.

We report a case of necrotizing fasciitis involving Streptococcus agalactiae, Arcanobacterium haemolyticum, and Finegoldia magna in a 36-yr-old female diabetic patient, which started after a minor dog bite to the toe of the patient. This case suggested that a trivial infection after a minor dog bite in an immunocompromised patient such as diabetes patient could result in a significant complication such as necrotizing fasciitis. The life-threatening infection was cured by timely above-the-knee amputation, as well as penicillin G and clindamycin therapy.

OBJECTIVEGroup A β-hemolytic streptococcus (GAS) or Streptococcus pyogenes may be encountered in diverse clinical situations in children. A rising incidence of invasive group A streptococcus (IGAS) infections has been noted in children in the past three decades. The aim of this study was to summarize the clinical characteristics and antimicrobial resistance of IGAS in children, and to raise the level of diagnosis and treatment of this infection.
METHODThe clinical data from 19 cases of IGAS younger than 14 years old seen from January 2004 to December 2011 treated in the authors' hospital were analyzed. IGAS infections are defined as the isolation of GAS from a normally sterile site in patients.
RESULTThe 19 cases were identified as IGAS infections, among whom 15 were male and 4 were female, and the ratio of them was 3.75. The age ranged from 1 day to 14 years, with a median age of 4 years. The course of disease was 4 h-10 days. The average length of stay was 12.2 days. In 13 cases the episodes of the infection occurred in winter and spring. In 18 cases the infection was community-acquired. Overall, 10 cases had neck or foot dorsum abscess, four cases had purulent peritonitis, and 3 cases were diagnosed as streptococcal toxic shock syndrome (STSS) complicated with empyema, pyopneumothorax occurred in 1 case and neonatal septicemia in another. Three cases had an underlying disease, including 2 cases wounded in a car accident and 1 case of congenital esophageal atresia and tracheoesophageal fistula. Before the isolation of GAS, 5 cases had stayed in ICUs, the length of ICU stay was 1-32 days, 4 cases had received intubation and mechanical ventilation, the ventilation time was 8 h-24 days, 2 cases had received major surgery; 5 cases had other pathogen coinfection, including 4 cases of abdominal pus at the same time and Escherichia coli was isolated, and 1 case had parainfluenza virus type I coinfection. Peripheral blood leucocyte increased in 18 cases, one case dropped off. The C-reactive protein (CRP) levels increased in all patients, including 16 cases who had 14-160 mg/L, 3 cases had levels higher than 160 mg/L. Twenty strains of GAS were isolated from 19 cases' sterile sites, of them 10 strains were isolated from abscess, 4 strains were isolated from blood and another 4 from ascites. Two strains were from the same patient at different times of pleural effusion. All 20 strains displayed a full susceptibility to cefazolin, levofloxacin and vancomycin, and the rates of resistance to both cefotaxime and penicillin were 10.0%. The rates of resistance to erythromycin and clindamycin were 55.0% and 70.0% respectively. Among the patients 3 cases were cured, 14 cases improved, and 2 cases died, of whom 1 case died of STSS secondary to multiple organ dysfunction, 1 case died of basic disease secondary to multiple organ dysfunction.
CONCLUSIONSkin and soft tissues were the most common IGAS infection sites in children, and IGAS infection also can lead to serious STSS and even can be life threatening. Penicillin and cephalosporin are still sensitive for children IGAS infections.
