Objective To explore the effect of family doctor contract service on infant growth and development and incidence of pneumonia. Methods From July 2019 to February 2020, 200 infants in Longfeng community were selected as the research objects and randomly divided into contract group and non contract group, with 100 cases in each group. Among them, the infants in the contract group received the family doctor contract service, while the infants in the non signing group received the community routine child health care services. The growth and development indexes (body length, body weight), neuropsychological development indexes (big movements, fine movements, personal society, language, adaptability) and the incidence of pneumonia were recorded and analyzed in the first, third, sixth, ninth and twelfth months after birth. Results There were no significant differences in height and weight between the two groups at the first and third month after birth (P>0.05). From the 6th month after birth, the height and weight of infants in the signing group were higher than those in the non signing group (P<0.05). There were no significant differences in the 5 indexes of development quotient between the two groups (P>0.05). At the age of 12 months, the scores of big movement, fine movement, personal society, language and adaptability of infants in contract group were higher than those in non contract group (P<0.05). By the end of the 12th month after birth, there were 2 cases of pneumonia in the signing group, the incidence of pneumonia was 2%; in the non signing group, there were 10 cases of pneumonia, the incidence of pneumonia was 10%, which was higher than that of the signing group. All children with pneumonia were cured after active symptomatic treatment. Conclusion Family doctor contract service can promote the physical and mental development level of infants and young children in the first year after birth, at the same time, it can effectively reduce the risk of pneumonia, which is conducive to the comprehensive and healthy development and growth of infants and young children. It has significant health and sociological value and is worthy of promotion and application.

Objective To investigate the clinical features of infantile allergic proctocolitis and its endoscopic lesions and pathological features. Methods A retrospective analysis of 110 cases of infantile allergic proctocolitis admitted to our hospital from January 2016 to December 2018 and its colonoscopy and pathological results, food allergen-specific IgG, blood routine, fecal routine, serum total IgE detection and treatment. Results Among 110 patients with allergic proctocolitis, 67 were male and 43 were female, 98 were < 6 months old; 26 were breastfed exclusively, 19 were fed milk alone, and 65 were mixed feeding. The clinical manifestations were diarrhea, most of children with bloody stools (93 cases), some children with eczema (23 cases), defecation and crying (67 cases), restless sleep (61 cases), vomiting (8 cases), malnutrition (6 cases); blood eosinophils increased in 63 cases,serum total IgE increased in 21 cases. Food allergen-specific IgG test results:103 cases of milk, 62 cases of eggs. Endoscopic lesions involved the descending colon, sigmoid colon, rectum, 76 cases of transverse colon, 47 cases of ascending colon and 18 cases of ileocecal. Most common manifested as herpes-like changes (106 cases), erosion (97 cases), ulcers (13 cases). Histopathology showed 91 cases of intestinal mucosal eosinophil infiltration, 21 cases of cryptitis and crypt hyperplasia, 18 cases of lymphoid follicle formation and 4 cases of superficial ulcer formation. 18 cases were improved after the mother evaded diet. 8 cases were improved by feding with amino acid milk powder for one week, and then breast milk was gradually introduced; 19 cases were improved after switching to deep hydrolysis or amino acid milk powder. 65 cases were improved after switching to deep hydrolysis or amino acid milk powder and simultaneously the mother evaded diet. Conclusion Infantile allergic proctocolitis lack of insufficient specific manifestations, most of the clinical cases are good, only a few are complicated by malnutrition. Milk is the most important allergen. Diarrhea, history of blood in the stool, elevated blood eosinophils, intestinal herpes-like changes, bowel mucosal eosinophil infiltration, are suggesting a high possibility of allergic proctocolitis. Mothers avoiding diet or switching to amino acids or deep hydrolyzed milk powder treatment is also effective, and this is also the standard of diagnosis of proctocolitis.

Objective We aimed to analyze the clinical characteristics of community acquired purulent meningitis(PM) in infants and explore the predictors of early diagnosis. Methods Retrospective study was done with patients in our NICU from Jan 2015 to Dec 2017 aged during 29 days to 90 days. We divided them into two groups, 53 of which diagnosed PM were included as a case group, while 81 of which admitted inpatients with fever at the same periods and in the same age ranges were included as a control group. Factors including adverse basic events, clinical manifestations, laboratory examinations and so on were compared between two groups. Results Univariate analysis showed that premature, manifestations such as irritability, lethargy, bulging fontanelle,a stiff neck and the poor circulation, and cerebrospinal fluid(CSF) data like the mount of white blood cell, concentration of CSF protein, concentration of CSF glucose, CSF/blood glucose ratio, concentration of CSF lactate dehydrogenase were different between two groups. In the multivariate analysis, concentration of CSF Protein(＞0.450 g/L, OR=5.819, P=0.002) and concentration of CSF lactate dehydrogenase(＞28.300 U/L,OR=7.892, P＜0.001) were proven to be independent risk factors for the diagnosis of PM. Receiver operating characteristic (ROC) analysis revealed that the CSF protein, the CSF lactate dehydrogenase and the combination of the two factors had an increased area under the curve (AUC), the mounts of each which were 0.839,0.867 and 0.890. Conclusion Patients with PM in early infantile period are often lack of atypical clinical characteristics. We need pay highly attention to the adverse basic events, irritability, lethargy, bulging fontanelle,a stiff neck, poor circulation and CSF results. The independent predictors for early diagnosis were concentration of CSF protein and lactate dehydrogenase. It indicates that if the predictors could be identified early, diagnosis could be made timely and interventions could be operated immediately. It will be beneficial for progression-free and overall survival.
