OBJECTIVETo analyze the clinical and pathological features of 40 patients with secondary syphilis.

METHODSA total of 40 cases of secondary syphilis confirmed by serology were collected during 1994-2004 and were first diagnosed on presentation with oral lesions.

RESULTSThe white patch in oral mucosa was found in 32 cases with painless or slight pain in most cases. The most common site of the lesion was the tongue. The histological examination on eight cases was initially misdiagnosed as oral candidosis or lichen planus, but confirmed as syphilis after serology revealed nonspecific inflammation with intraepithelial microabscess and dense perivascular infiltration of lymphocytes and plasma cells in connective tissue. The symptoms showed dramatic improvement in 16 cases after benzathine penicillin treatment.

CONCLUSIONSThe oral manifestations of syphilis have specific clinical and pathological feature and attention should be paid to the suspicious oral lesions when patients are first presented in a dental office.

OBJECTIVE: To investigate the risk factors of oral ulcers and bloodstream infection in patients with hematopoietic stem cell transplantation. METHODS: The clinical data of 401 hematopoietic stem cell transplant patients in the First Affiliated Hospital of Zhengzhou University from January 2020 to December 2021 were retrospective analyzed, and the risk factors of oral ulcers and bloodstream infection statistical and analyzed. RESULTS: Among the 401 patients, the incidence of oral ulcers was 61.3% (246/401), and the incidence of bloodstream infection was 9.0% (36/401). A total of 40 strains of pathogenic bacteria were isolated from 36 patients, including 26 strains of Gram negative strains (65%), 13 strains of Gram positive strains (32.5%), and 1 strain of fungi (2.5%). Single-factor analysis showed that oral hygiene was associated with the occurrence of bloodstream infection, and the Multi-factor analysis showed that age ≥14 years old, disease diagnosis of leukemia, and allogeneic hematopoietic stem cell transplantation were risk factors for oral ulcers. CONCLUSION The incidence of oral ulcers in patients with hematopoietic stem cell transplantation is high. The age ≥14 years, disease diagnosis of leukemia, and allogeneic hematopoietic stem cell transplantation were risk factors for oral ulcers in patients, and oral hygiene was associated with the occurrence of bloodstream infection.

Pyoderma gangrenosum (PG) is a rare, noninfectious neutrophilic dermatosis. Clinically, it begins with sterile pustules that rapidly progress into painful ulcers of variable depth and size with undermined violaceous borders. The diagnosis of PG is based on the history of an underlying disease, a typical clinical presentation, histopathology, and exclusion of other diseases. The peak incidence occurs between the ages of 20 to 50 years with women being more often affected than men. There have been very few reports of pyoderma gangrenosum with oral mucosal involvement. Oral lesions in previously reported cases have included ulcers of varying sizes from a few mm to several cm and have been reported to have been found on the tongue, soft and hard palate, buccal mucosa, and gingiva. Some of these oral lesions have been associated with ulcerative colitis, inflammatory bowel disease, and polycythemia rubra vera. A few cases were reported with biopsy findings, the histological picture being nonspecific, showing ulceration, and necrosis with inflammatory cell infiltrate. A peculiar case of pyoderma gangrenosum with an oral lesion is presented here, and the differential diagnosis is discussed.

In order to get clinical information about safety and feasibility of successively double autologous hemopoietic stem cell transplants (SD-AHSCT) in malignant hematological disease patients, the complications and hematological reconstitution after SD-AHSCT in 20 patients were analyzed retrospectively. 20 patients with hematologic malignancies received autologous peripheral blood stem/progenitor cell transplantation at the first transplant, and then were given autologous bone marrow transplantation as the second transplant at 4-10 months. The results showed that all the patients tolerated mobilization and collection of peripheral blood stem/progenitor cells as well as bone marrow collection. All the patients got enough hematological stem/progenitor cells for SD-AHSCT and achieved hematological reconstitution after SD-AHSCT. The speed of hematological reconstitution was positively correlated with the transfused quantity of hematological stem/progenitor cells (r = 0.968). The hematological reconstitution after the first autologous hemopoietic stem cell transplant (AHSCT) was earlier than that of the second (P < 0.05). There was no statistical difference between the first and the second AHSCT for the incidence of skin or mucous membrane bleeding (P > 0.05). No patients occurred massive hemorrhage during SD-AHSCT. The quantity of platelet transfusion in the second AHSCT was larger than that in the first AHSCT (P < 0.01). The incidence of oral ulcer in the first AHSCT was significantly higher than that in the second (P < 0.01). No statistical difference between the first and the second AHSCT was there in infectious sites, infectious pathogens and infection incidence (P > 0.10). All the complications were improved or cured, and no patients died of SD-AHSCT complications. In conclusion, SD-AHSCT is safe and feasible, and worthy to be further popularized.

Severe congenital neutropenia is a rare hematological disease characterized by a selective decrease in circulating neutrophils, maturation arrest of granulocytic precursors at the promyelocyte stage, and recurrence of infections. A 2-month-old male infant (patient A) and a 14-month-old female child (patient B) were referred to our hospital due to severe neutropenia. Sequencing analysis of ELA2 and HAX1 genes was performed. Two single nucleotide polymorphisms of HAX1 gene were found. They were 5,104T-->G point mutation of exon 1 and 5,474A-->G point mutation of intron 1 in HAX1 gene. The mutation of ELA2 gene was not found. The patient A showed a good response to granulocyte colony-stimulating factor (G-CSF) treatment and the absolute neutrophil count recovered to 1,195/microliter. But the patient B showed a partial response to G-CSF treatment and experienced several episodes of herpetic gingivostomatitis, oral ulcer, acute pharyngotonsillitis and otitis media during follow-up.
