Bilateral bartholin's gland abscesses in a 4-year-old girl with vitamin a deficiency: a case report.

BACKGROUND: A Bartholin's gland abscess is one of the most common infections in women of reproductive age. Although Bartholin's gland abscesses have been reported in prepubertal children, they are rarer in prepubertal children than in adults. Herein, we report a case of bilateral Bartholin's gland abscesses in a 4-year-old girl with vitamin A deficiency. CASE PRESENTATION: A 4-year-old girl diagnosed with autism spectrum disorder was admitted to the hospital for close examination and treatment because of persistent fever and malaise. The child was a marked fussy eater and was diagnosed with corneal ulceration and night blindness secondary to vitamin A deficiency. Both of the patient's labia were swollen, and a diagnosis of a bilateral Bartholin's gland abscess was made using computed tomography. Incisional drainage was performed under general anesthesia. The patient's postoperative course was uneventful, and she was discharged from the hospital on day 8 after the surgery. During hospitalization, attempts were made to correct the vitamin deficiency by adding nutritional supplements to the diet. Three months after the surgery, no recurrence of abscesses was noted. CONCLUSIONS: Decreased immunocompetence and mucosal barrier function due to vitamin A deficiency is thought to be the underlying cause of Bartholin's gland abscesses. Although prepubertal Bartholin's gland abscesses have been reported, they are rare. To the best of our knowledge, no reports of bilateral Bartholin's gland abscesses potentially caused by vitamin A deficiency have been reported. When prepubertal girls present with Bartholin's gland abscesses, the presence of immunodeficiency due to vitamin or trace element deficiency should also be considered.

Anaplastic Carcinoma Arising From Ovarian Mucinous Adenocarcinoma With Massive Cardiopulmonary Metastasis: An Autopsy Case Report.

BACKGROUND: The presence of anaplastic and sarcomatoid components in ovarian mucinous carcinoma is extremely rare. CASE: A 64-year-old woman underwent radical surgery for right ovarian cancer. Pathological examination showed mucinous adenocarcinoma with a focal mural nodule of anaplastic and sarcomatoid carcinoma (FIGO stage IIB). She underwent adjuvant chemotherapy but developed severe respiratory failure and died after 9 months. Autopsy showed that the bilateral pulmonary parenchyma was filled with a multinodular hemorrhagic mass, and the cardiac wall had a massive invasive lesion. Histopathological examination of the lung and myocardium revealed diffuse invasion of the anaplastic carcinoma component with infiltrating osteoclastic giant cells. CONCLUSION: This case is very rare, and the clinical management of anaplastic carcinoma arising in mucinous neoplasms remains challenging.

Current Status and Problems of Newborn Infection Management at a Regional Hospital in Japan.

PURPOSE: To clarify neonatal bacterial infection management in near term and term infants at a regional hospital in Japan. METHODS: Between 2018 and 2020, of 729 births, 236 patients who underwent blood examination at least twice by the age of 3 days, were included. Data from the medical records were analyzed retrospectively. RESULTS: Median gestational age was 39 weeks, with 116 boys (49.1%) and 202 vaginal deliveries (85.6%). There were 37 cases of maternal group B streptococcus, 24 cases of premature rupture of membranes for more than 24 hours (PROM group), and 107 cases of amniotic fluid turbidity at birth (AFT group). Comparing groups, C-reactive protein (CRP) was significantly lower in the cesarean section (C/S) group (median 0.22 mg/dL; p < 0.05), and higher in the AFT group (0.44 mg/dL; p < 0.05). There were 77 positive cultures, (p < 0.05). Antibiotics were administered more frequently in cesarean section (19 cases; p < 0.001) and less in the PROM group (2 cases; p < 0.01). CONCLUSIONS: There were no asymptomatic cases of CRP >2 mg/dL, and no cases of severe sepsis in normal neonatal deliveries. CRP levels were elevated in the AFT group, where culture was positive, but few antibiotics were administered. In the C/S group, antibiotics were administered if respiratory symptoms occurred unless the CRP level was high. Further, all patients in PROM group who received antibiotics had any symptoms, suggesting that routine blood tests may not be necessary.

Diagnosis of Leiomyosarcoma after Uterine Artery Embolization for Multiple Leiomyomas.

Uterine sarcoma is significantly rarer than leiomyoma and has poor prognosis. Moreover, the diagnosis of leiomyosarcoma is difficult because its symptoms, including pelvic pain, uterine mass, and/or uterine bleeding, are very similar to those of leiomyoma. There are a few cases of leiomyosarcoma wherein leiomyoma was treated with uterine artery embolization (UAE); these reports revealed that the symptoms of hypermenorrhea or/and pelvic pain persisted even after UAE. Symptoms persisting even after UAE treatment for leiomyomas, especially multiple leiomyomas, should be investigated to rule out leiomyosarcoma. Therefore, long-term follow-up is needed. Here, we describe a case of a 39-year-old woman diagnosed with leiomyosarcoma 3 years after undergoing UAE for multiple leiomyomas.

Physiological role of carbon dioxide in spore germination of Clostridium perfringens S40.

Germination of Clostridium perfringens is known to be triggered by nutrients such as l-alanine and inosine, and facilitated by CO2, however the role of CO2 has not been fully understood. During the studies of the germination-specific protease GSP, we found that CO2 could be replaced by bicarbonate or weakly acidic pH (pH 6.0-6.5). We also found that the spores obtained from the C. perfringens S40 overproducing GSP could germinate without CO2. Moreover, the spores could germinate in the absence of nutrients, when the spores were incubated with bicarbonate or under weakly acidic pH. GSP, which might consist of three homologous proteases, CspA, CspB, and CspC, is one of the key enzymes involved in the spore germination, and converts the pre-mature form of the spore cortex-lytic enzyme, SleC, to the mature form. Maturation of SleC in the spores obtained from the mother strain of C. perfringens S40 requires nutrients plus bicarbonate or weakly acidic pH. In contrast, mature SleC was found in the spores obtained from the cells overpoducing GSP, when the spores were treated by nutrients, bicarbonate or weakly acidic pH. Each nutrients, bicarbonate and weakly acidic pH can trigger the germination of the spores obtained from C. perfringens cells overproducing GSP.
