Obstetric Clinical Analysis in 8 Cases With Cushing’s Syndrome / 中山大学学报(医学科学版)

ObjectiveTo summarize and analyze the clinical characteristics， diagnosis process， treatment process， and obstetric outcomes of pregnant women with Cushing's syndrome， helping to optimize pregnancy management. MethodsA retrospective study was conducted on 8 pregnant women with Cushing’s syndrome who were hospitalized in the First Affiliated Hospital， Sun Yat-sen University between January 2006 and August 2022. The clinical characteristics， management and obstetric outcomes were recorded. ResultsPreeclampsia was detected in 4 cases，pre-gestational diabetes mellitus in 2 cases， gestational diabetes mellitus in 5 cases， and hypokalemia in all 8 cases. Elevated serum cortisol， disappearance of day-night rhythm of cortisol， increased 24-hour urine cortisol and decrease in serum ACTH were found in 8 cases by laboratory examination. Furthermore， adrenal adenoma was detected in all 8 cases by ultrasonography or Magnetic Resonance Imaging. Three cases underwent laparoscopic adrenalectomy in the second trimester and 4 cases received surgery after delivery. The diagnosis of adrenal cortical adenoma was confirmed by pathological report. Six cases had preterm birth， while one patient delivered after 37 weeks of gestation and one patient suffered from spontaneous abortion. Among 7 cases of live birth， 6 patients underwent cesarean section and 1 patient had vaginal delivery. Of all newborns， 3 had low birth weight. One case had a birth defect. Four infants were transferred to the neonatal intensive care unit， and two infants died. One child was diagnosed with nephrotic syndrome at 2 years of age. ConclusionsCushing's syndrome is rare and high risk during pregnancy. It requires multidisciplinary diagnosis， treatment， and long-term follow-up. Drug therapy carries a risk of progression and requires intensive care during pregnancy， postpartum follow-up， and specialist treatment.

Clinical Characteristics and Obstetric Outcomes of Pregnant Women Who Underwent Surgery for Adnexal Torsion / 中山大学学报(医学科学版)

ObjectiveTo explore the clinical characteristics and obstetric outcomes of pregnant women who underwent surgery for adnexal torsion at different gestational weeks. MethodsA retrospective study was done on 39 women who underwent surgery for adnexal torsion during pregnancy in the First Affiliated Hospital， Sun Yat-sen University between March 2013 and March 2023， with 18 cases in 1st trimester （<14 weeks）， 11 in 2nd trimester （14-27+6 weeks） and 10 in 3rd trimester （≥28 weeks）. The clinical characteristics， treatment and obstetric outcomes were compared among the three groups. ResultsThe 1st trimester group had higher proportion of assisted reproductive technology （ART） use than the 2nd and 3rd trimester groups （P=0.026）. There was no significant difference in the clinical manifestations， including abdominal pain， nausea， vomiting and fever among the three groups， while elevated white blood cells （WBC） counts was more commonly seen in the 2nd and 3rd trimester groups. Adnexal masses <5 cm in diameter occurred in 0， 18.2%， and 10.0% of cases in 1st， 2nd and 3rd trimester groups respectively （P=0.014）. No statistical significance was found in the location of twisted adnexa， number of circles or pathological nature. The 1st trimester group had a higher sensitivity of ultrasound in the diagnosis of adnexal torsion compared with the 2nd and 3rd trimester groups （77.8%， 36.4%， 20.0%； P=0.008）. More laparoscopic surgery were performed in the 1st trimester group than the other two groups （55.6% ， 27.3%， 0.0%； P=0.008）. There was no significant difference in gestational week of delivery， delivery mode， newborn gender， neonatal birth weight and follow-up of newborns among the three groups. The 3rd trimester group showed a higher risk of preterm delivery （P=0.050）. ConclusionsDuring the 1st trimester of pregnancy， adnexal torsion is more common in patients using ART and ultrasound plays a crucial role in the diagnosis. During the 2nd and 3rd trimester， adnexal torsion should be suspected in patients with abdominal pain and elevated WBC but no aspetic inflammation. Laparoscopic surgery is safe for adnexal torsion during pregnancy and can achieve a favorable maternal and neonatal outcome.

Anti-mycobacteria drugs therapy for periductal mastitis with fistula / 中华外科杂志

<p><b>OBJECTIVES</b>To study the etiology, clinical and pathologic characteristics of periductal mastitis with fistula and estimate the effect of anti-mycobacterial agents for periductal mastitis with fistula.</p><p><b>METHODS</b>Totally 27 patients of periductal mastitis with fistula received anti-mycobacteria drugs therapy from December 2008 to September 2011 were analyzed retrospectively. All of the patients were female. The mean age at onset was 28 years (range 15 to 40 years old). The main clinical manifestation of the 27 patients was breast fistula, including 21 patients with single fistula and 6 patients with multiple fistula. Three patients manifested with pure fistula, 14 patients with both fistula and lump, 10 patients with fistula, lump and abscess. The samples including pus or tissues of all patients were underwent bacteria culture and all patients core needle biopsy. All patients were given primary anti-mycobacteria drugs therapy, parts of patients received surgery based on the evaluation of medical treatment.</p><p><b>RESULTS</b>The common bacteria culture of all patients failed to demonstrate any causative microorganism. Four cases were selected randomly to undergo PCR of mycobacteria, only one case was identified as Massiliense in bacteria culture of mycobacteria. Twenty-seven patients with periductal mastitis with fistula were treated with anti-mycobacterial agents (isoniazid, rifampicin and ethambutol or pyrazinamide of triple oral drugs) for 1 to 3 months, the fistula of all 27 patients were closed well. Sixteen patients were treated with the agents only and cured. Eleven patients received surgical treatment after treated with the medical agents. None of the patients were given mastectomy. All patients had no reccurence until now.</p><p><b>CONCLUSIONS</b>The periductal mastitis with fistula has a closely relationship with the infection of nontuberculosis mycobacteria. Those patients could be treated with triple anti-mycobacterial agents and could also avoided mastectomy.</p>

The clinical study of high-frequency ultrasound-guided vacuum-assisted biopsy for breast microcalcifications / 中华外科杂志

<p><b>OBJECTIVE</b>To evaluate the clinical application of high-frequency ultrasound-guided vacuum-assisted biopsy for breast microcalcifications.</p><p><b>METHODS</b>Sixty-six patients with 70 lesions of microcalcifications detected at mammography underwent high-frequency ultrasound-guided vacuum-assisted biopsy from July 2009 to October 2010. All patients were female, aged 24 to 61 years (median age 40 years). Among 70 lesions of microcalcifications, unilateral lesions were 62 cases and bilateral lesions were 4 cases. The clinical factors that affected the success of biopsy were investigated by χ(2) test and Logistic regression analysis.</p><p><b>RESULTS</b>Among 70 lesions of microcalcifications, the successful rate of biopsy was 72.9% (51/70). The biopsy successful rate of microcalcifications without and with masses were 65.2% (30/46) and 87.5% (21/34) respectively (χ(2) = 3.960, P = 0.047). The biopsy successful rate of microcalcifications of maximal diameter more than 5 mm was higher than that of maximal diameter less than 5 mm (88.9% vs. 55.9%, χ(2) = 9.633, P = 0.002). The Logistic regression analysis showed that the types and maximal diameter of microcalcifications were the main factors that affected the success of biopsy.</p><p><b>CONCLUSION</b>The clinical application of high-frequency ultrasound-guided vacuum-assisted biopsy was an effective option for the diagnosis of breast microcalcifications, especially for the type of microcalcifications with masses and the maximal diameter more than 5 mm.</p>
