Laparoscopic Anterior Pelvic Exenteration with Super Radical Parametrectomy for a Recurrent Low-Grade Endometrial Sarcoma That is Resistant to Hormone Therapy and Chemotherapy.

STUDY OBJECTIVE: To show total laparoscopic complete resection of a recurrent low-grade endometrial sarcoma. DESIGN: Step-by-step demonstration of the technique of laparoscopic anterior pelvic exenteration with super radical parametrectomy, including the explanation of detailed pelvic anatomy (Canadian Task Force classification III). SETTING: Low-grade endometrial stromal sarcoma (LGESS) is a rare malignancy that makes up around 0.2% of all uterine malignancies [1]. Total abdominal hysterectomy and bilateral salpingo-oophorectomy is a standard treatment; however, the recurrence risk is quite high [2]. For a recurrent LGESS that is resistant to hormone therapy and chemotherapy, complete resection with negative surgical margins (R0 resection) can be the most promising method [3]. PATIENT: The patient had undergone total abdominal hysterectomy and bilateral salpingo-oophorectomy because of a LGESS. Almost 20 years later, a recurrent LGESS was detected at the vaginal stump, and the patient underwent several rounds of chemotherapy and hormonal therapy. These treatments were inefficacious, and the recurrent tumor progressed. An abdominal computed tomographic scan revealed that the recurrent tumor occupied the vaginal stump, involved the bladder and the left ureter, and extended to the left pelvic sidewall. INTERVENTIONS: Anterior pelvic exenteration with super radical parametrectomy was performed laparoscopically with no blood transfusion. R0 resection could be achieved without any intraoperative and postoperative complications. Without any adjuvant treatment, there has been no sign of recurrence during the 12 months that have passed since the surgery. This video obtained institutional review board approval through our local ethics committee in the Cancer Institutional Hospital (institutional review board number 2016-1007). CONCLUSION: The good visualization and meticulous dissection provided during laparoscopic surgery can make the approach advantageous and may contribute to R0 achievement.

Oral leukoplakia, a precancerous lesion of squamous cell carcinoma, in patients with long-term pegylated liposomal doxorubicin treatment.

Pegylated liposomal doxorubicin (PLD) has a good safety profile, but long-term use has been associated with development of squamous cell carcinoma of the tongue and oral cavity (SCCTO) in some patients. The study objective was to estimate the prevalence of oral leukoplakia, a known precursor of SCCTO, in patients with ovarian cancer and long-term PLD use.After approval of the institutional review board, medical record of 114 patients who were treated with PLD at our institution between January 2010 and December 2016 were retrospectively reviewed. All those patients have been referred for routine monitoring of oral mucositis every time before administration by a dentist. The patient characteristics included in the evaluation were age, smoking and drinking habits, the PLD dose and schedule, and presence or absence of oral leukoplakia and SCCTO at each oral examination. The relationships of the incidence of oral leukoplakia and patient characteristics were analyzed.The median total PLD dose was 160 (range 40-1550) mg/m. Oral leukoplakia was seen in 6 (5.3%) patients. The median PLD dose, at the time of oral leukoplakia diagnosis, was 685 (range 400-800) mg/m. SCCTO was not found. Univariate analysis revealed that age, Brinkman index, and habitual drinking were not considered as risk factors for oral leukoplakia, and only total PLD dose (OR, 1.470; 95% CI, 1.19-1.91; P < .001) remained as a significant independent risk factor for oral leukoplakia. The ROC curve analysis indicated that the optimal cutoff value of the total PLD dose to predict development of oral leukoplakia was 400 mg/m. The sensitivity was 100% and the specificity was 88.8%. No patient discontinued PLD because of oral leukoplakia or SCCTO.The 2 most important clinical observations were the occurrence of oral leukoplakia in patients with long-term PLD use and that the development of oral leukoplakia was related to a total cumulative dose ≥400 mg/m. Routine oral surveillance is recommended, particularly when the cumulative total dose exceeds 400 mg/m.

[Two adolescent cases of pseudoseizure with mental retardation].

We experienced two cases of complicated pseudoseizure, whose diagnosis and treatment were based on Kretschmer's concept of "primitive hysteria". The first case was a 16-year-old boy who experienced a convulsion before a swimming class which he disliked. He was immediately brought to the emergency department of our hospital. Initially, he was treated as a true epileptic patient, and his convulsion continued for hours. We monitored the patient by video, which aided in making a precise diagnosis. He also showed a pain disorder. The second case was a 16-year-old girl who developed hyperventilation and convulsion during her graduation ceremony. The characteristics of her convulsion were similar to the first case. Four days after her admission to our hospital, we concluded that her symptoms were a part of primitive hysteria. After her discharge, she experienced some intermittent episodes of convulsion. There was also a possibility of sexual abuse from her father. Both patients had a family history of mental retardation and an unstable home life, as well as similar symptoms. Even in a modern general hospital, there is a lack of understanding about pseudoseizure, thus, medication may be unnecessary for undiagnosed patients. DSM-IV-TR as well as ICD-10 criteria do not mention anything about primitive hysteria. However, we recommend revitalization of this concept because it is a useful, appropriate, and necessary description of pseudoseizure with complications.
