AIM:To compare the clinical efficacy of three combined surgical treatments for cataract induced by silicone oil -filled eye.
METHODS: The data of 75 eyes of 75 patients with cataract induced by silicone oil-filled eye were reviewed. Those patients were divided into group A, B, C. The patients in group A were treated by phacoemulsification combined with silicone oil removal through pupil and IOL implantation, the patients in group B were treated by phacoemulsification combined with silicone oil removal through 23G vitrectomy system and IOL implantation, the patients in group C were treated by phacoemulsification combined with silicone oil removal through 20G vitrectomy system and IOL implantation. The operation time, intraocular pressure, best corrected visual acuity ( BCVA ) , discomfort days and complications before and after the surgery were compared.
RESULTS: The differences of the intraocular pressure were not statistically significant between the three groups after the surgery. The BCVA of the three groups were all improved, but the differences were not statistically significant between three groups. The differences in postoperative complications showed no statistically significant. Otherwise, group A and B cost less operation time. The discomfort days of group A were less than other groups.
CONCLUSION: Three different surgical methods were safe and effective, appropriate surgical approach could be chosen according to the patients' clinical manifestations. For patients with cataract induced by silicone oil-filled eye whose retina recovered well, phacoemulsification combined with silicone oil removal through pupil and IOL implantation is a time-saving, safe and effective method.

Objective To assess the effectiveness of supracricoid partial laryngectomy in the treatment of laryngeal cancer. Methods This study infiuded 22 patients operated on from 1993 to 2000 using this surgical procedure. 22 were males with mean age of 63 years (ranging from 43 to 74 years). 21 were glottic cancers (3 T1aNoMo, 4 T1bNoMo, 11 T2NoMo, 3 T3NoMo) and 1 supraglottic cancer (T2N1Mo) according to the 1997 UICC system. Supracrieoid partial laryngectomy was performed, with the epiglottis preserved and reconstructed with cricohyoidoepiglottopexy (CHEP). Results The overall 3-year and S-year survival rates were 88.24% and 70%, respectively. All patients were decannulated. The average time for decannulation was 25 days (ranging from 14 to 60 days). Speech was good in all cases. Conclusion CHEP not only excises the neoplasms completely and safely but also preserves the laryngeal physiologic function well.

Abstract: Objective To explore the clinical characteristics of nucleic acid negative newborns delivered by pregnant women infected with SARS-CoV-2 (Omicron variant BA. 5.1.3) in Sanya area, and to provide evidence for understanding its clinical characteristics. Methods A retrospective analysis was performed on 14 neonates with negative nucleic acid delivered by pregnant women who tested positive for SARS-CoV-2 (Omicron variant BA.5.1.3) in Sanya Central Hospital (the Third People's Hospital of Hainan Province) from June 2022 to September 2022 (observation group, n=14). The corresponding nucleic acid-negative newborns delivered by pregnant women detected negative with SARS-CoV-2 (Omicronon variant strain BA.5.1.3) were set as the control group (n=56), and the general data and clinical characteristics of neonates in the two groups were compared. Results There was no significant difference between the observation group and the control group in pregnancy diabetes, pregnancy induced hypertension, gestational pre-eclampsia, fetal intrauterine distress, premature rupture of membranes (P>0.05); there was no significant difference between the observation group and the control group in terms of sex, gestational age, birth weight, age, mode of delivery, birth Apgar score, heart screening, pulmonary disease, glucose 6-phosphate dehydrogenase (G6PD) deficiency, thalassemia, breast milk jaundice, hemolytic jaundice (P>0.05). The bilirubin level, blue light irradiation cases and the duration of blue light irradiation of the newborns in the observation group at 7 days after birth were higher than those in the control group (P<0.05); the ratio of blood oxygen saturation ≥ 90% in the observation group was lower than that in the control group (21.43% vs 89.29%, P<0.05), and the ratio of blood oxygen saturation occasionally<90% was higher than that in the control group (57.14% vs 10.71%, P<0.05). The ratio of blood oxygen saturation<90% had no significant difference compared with that in the control group (7.14% vs 0, P>0.05), and the ratio of blood oxygen saturation reduced to the required oxygen uptake was higher than that in the control group (14.29% vs 0, P<0.05). Conclusions The jaundice manifestation of the nucleic acid-negative newborns delivered by pregnant women infected with SARS-CoV-2 (Omicronon variant strain BA.5.1.3) in Sanya area is relatively obvious, with blood oxygen saturation easily lower than 90% and even requiring oxygen inhalation in severe cases.

Objective:To summarize the clinical characteristics, diagnosis and treatment of caspase recruitment domain-containing protein 9 (CARD9) gene deficiency associated invasive candidiasis, and report a novel mutation in CARD9 gene.Methods:The clinical characteristics, laboratory tests, treatment and the outcome of follow-up in a boy with invasive candidiasis were described. The boy′s main clinical manifestations were central nervous system infection and retroperitoneal mass. Whole-exome sequencing was performed and Sanger sequencing was verified to identify the CARD9 gene mutations in the patient and his parents. A literature search for “CARD9”and “invasive candidiasis”was conducted in PubMed, Wanfang and CNKI databases from their establishment to May 2020.Results:A 10-year-old boy suffered onset symptom of chronic diarrhea, which lasted for two months. The symptom was followed by progressive neurological symptoms such as headache, vomiting, seizures and disorder of consciousness. His unusual medical history was absent. Candida albicans were cultured several times in cerebrospinal fluid and blood, and yeast-like fungi were found in the stool high power field of vision. Cerebral magnetic resonance imaging indicated obstructive hydrocephalus and abdominal CT scan showed retroperitoneal mass and thickening of the intestinal wall. The whole-exome sequencing analyses of blood samples from the boy and his parents were performed. The results showed that there was a homozygous mutation of c.952-12_956delinsAG in the CARD9 gene, which was an unreported pathogenic mutation. This was confirmed by Sanger sequencing. There was no significant relief from intravenous combined antifungal medications. After lateral ventricular drainage surgery and injection of amphotericin B into the lateral ventricle, improvement of clinical symptoms and cerebral spinal fluid abnormalities was observed after nine weeks, and the retroperitoneal mass shrank. At follow-up after four-month oral combined antifungal medications, the child had no complaint except fatigue. However, cerebral spinal fluid analysis showed increased protein level and decreased glucose. Persistent hydrocephalus and periventricular white matter abnormal signals were revealed on the brain magnetic resonance imaging and the smaller retroperitoneal mass than before on the abdominal CT scan. In addition to this case, totally 21 cases with CARD9 gene deficiency associated invasive candidiasis have been reported worldwide, most of which featured central nervous system infections.Conclusions:CARD9 gene deficiency is an autosomal recessive primary immunodeficiency that confers human susceptibility to fungal disease. The associated invasive candidiasis often affects the central nervous system and makes the patient severely ill. Adequate systemic antifungal therapies should be given, and patients with hydrocephalus need surgical treatment. A novel mutation is reported that expands the variant diversity of CARD9 gene. For patients with unexplained invasive candidiasis, including those without a history of previous recurrent infection, genetic testing is recommended for primary immunodeficiency including CARD9 gene deficiency.
