Even a “pigtail” distal end catheter can enter the epidural space after continuous paravertebral block

A woman with a medical history of breast cancer presented with chronic pain of the right hemithorax. To alleviate pain, a continuous paravertebral block was performed using a pigtail end catheter, introduced using ultrasound visualization (transversal technique at the inferior articular process of T6). Complete pain relief was observed. A few hours later, urinary retention was diagnosed and discharge from the ambulatory setting was canceled. On the following day, a new injection of local anesthetics through the catheter triggered paresthesia in the contralateral leg and a new urinary retention was diagnosed. A CT scan confirmed the epidural misplacement of the catheter. The latter was withdrawn, and the patient was released to home after the complete disappearance of her neurological symptoms. This case report highlights the risk of inadvertently misplacing the catheter into the epidural space during thoracic paravertebral block, even with a “pigtail” distal end type of catheter.     

Single-site port robotic-assisted hysterectomy: an update

Single-incision approach in robotic gynecology is a relatively new concept. The role of single-port systems in robotic hysterectomy, their advantages and disadvantages, as well as the technical challenges, are still under investigation. A systematic review was performed by searching in PubMed and Scopus databases. In 810 out of 1225 patients, hysterectomy was performed for non-neoplastic disease. Single-Site^® was the most common port system. Duration of the procedure and relative blood loss ranged from 60 to 311 min and 7 to 750 ml, respectively. The weight of the removed uteri ranged from 39 to 520 g. 4.9% of the included patients presented complications, among which bleeding, vaginal haematoma, laceration and dehiscence, umbilical hernia, and visceral injuries. Conversion rate to laparotomy reached 2.8%. Although some technical difficulties are still described in the literature, the single-port approach is becoming more standardized nowadays and performed by more surgeons. The initial phase of the learning curve can be achieved after five cases, while a proficiency in intracorporeal cuff suturing after 14 cases. Uterus weight and previous abdominal surgical history can still be limitations of the technique. Compared to our previous study, we can see that the technique has been used in more elderly or obese patients. The complication rate can reach 4.9% while the conversion rate can reach 2.8%. However, we consider that complication and conversion rates as well as surgical time could be improved with experience. Regarding post-operative pain and cosmetic outcomes, the lack of information do not allow us to draw any safe conclusions.     

The Role of Complementary and Alternative Medicine for the Management of Fibroids and Associated Symptomatology

This article discusses the role of complementary and alternative medicine (CAM) in the management of fibroids and associated symptomatology. Since there is such a paucity of direct research related to fibroids, conditions that are implicated in the causation of uterine fibroids and symptomatology that CAM treatments may or have been shown to make a difference are also considered.     

Sarcoma-like tumor originating from oligodendroglioma

We present a case of sarcoma occurring at a site of resected oligodendroglioma without preceding radiotherapy or chemotherapy. Oligosarcoma occurring at sites of resected oligodendroglioma or anaplastic oligodendroglioma with sarcomatous components are rare. Although meningioma or sarcoma-like lesions are sometimes reported after glioma-targeted radiotherapy, those without preceding radiotherapy are quite rare. Moreover, cases of sarcoma without oligodendroglial components occurring at a site of resected oligodendroglioma have never been reported. In this case, fluorescent in situ hybridization analysis revealed 1p/19q co-deletion in both the first tumor and second tumors. Additionally, immunohistochemistry revealed mutated isocitrate dehydrogenase 1 in both tumors. Taken together, these findings suggest a monoclonal tumor origin. Consequently, this case may indicate a new mechanism of development of sarcomatous lesions occurring at the site of a resected glioma.     

Evaluation of the comorbidity burden in patients with ankylosing spondylitis using a large US administrative claims data set

Comorbidities among US patients with ankylosing spondylitis (AS) are inadequately understood. This study compared the prevalence and incidence of comorbidities between patients with AS and matched controls using national claims databases. Adults enrolled in the MarketScan Commercial and Medicare databases with ≥?1 inpatient or ≥?2 non-rule-out outpatient diagnoses of AS between January 1, 2012 and December 31, 2014 were included. Patients had to have ≥?1 AS diagnosis in 2013; the first AS diagnosis in 2013 was assigned as the index date. Control patients without AS were matched to AS patients on age, geographic region, index calendar year, and sex. Comorbidities were evaluated in AS patients and matched controls during the baseline and follow-up periods (before and after the index date, respectively). Hazard ratios of developing new comorbidities were estimated using Cox proportional hazard models adjusted for patients’ characteristics. A total of 6679 patients with AS were matched to 19,951 control patients. In addition to extra-articular manifestations of AS (inflammatory bowel disease [IBD], psoriasis, uveitis), a higher proportion of AS patients had asthma, cardiovascular disease, depression, dyslipidemia, gastrointestinal ulcers, malignancies, multiple sclerosis, osteoporosis, sleep apnea, and spinal fractures during the baseline period than matched controls. After AS diagnosis, a higher proportion of patients developed newly diagnosed cases of cardiovascular diseases, depression, osteoporosis, spinal fracture, IBD, psoriasis, and uveitis than matched controls. In this real-world, US claims-based study, patients with AS were shown to have significantly more comorbidities than matched controls.     

Radioonkologische Aspekte des Zervixkarzinoms

Chemoradiotherapy is an integral component of cervical cancer treatment in cases where surgery alone is not sufficient to achieve an optimal oncological outcome. The present German interdisciplinary guidelines on treatment of cervical cancer recommend performing either radical hysterectomy or primary chemoradiotherapy. The frequently used practice of trimodal therapy (i.e. radical hysterectomy, radiation and chemotherapy) doubles the risk for treatment-related delayed toxicity and should be avoided whenever possible. If risk factors are known prior to therapy, e.?g. lymph node metastases, parametrial infiltration or a combination of tumor size >4 cm, grade 3, lymphovascular space invasion (LVSI) or deep stromal infiltration, primary chemoradiotherapy should be recommended. The purely clinical FIGO classification does not consider lymph node involvement. This leads to a high rate of adjuvant chemoradiotherapy after radical surgery due to lymph node involvement. This could have been avoided in 90?% of patients, if surgical (laparoscopic) lymph node staging would have been used routinely. Whether this can result in advantages for patients with respect to the prognosis, was one of the aims of the Uterus-11 study of the working group for gynecological oncology (AGO) and the working group on radiological oncology (ARO).Mature data are expected to be available in 2018. For chemoradiotherapy sophisticated irradiation techniques should be used, which are available in all German treatment facilities. This is the only way to reduce acute and delayed side effects. Although ovarian preservation by ovarian transposition and organ sparing can be provided to premenopausal patients, a pregnancy after full-dose chemoradiotherapy is unlikely because of the resulting atrophy of the endometrium and fibrosis of the myometrium. Oncological results depend on treatment quality, full-dose external beam radiation, the use of brachytherapy and the administration of concomittant chemotherapy. The experience of the treatment facility is a predictor for patient outcome. The value of neoadjuvant chemotherapy in locally advanced cervical cancer is unclear and still under discussion.     

Quality of Life and Long-Term Therapy in Patients with Chronic Myeloid Leukemia

Since the development of imatinib and other tyrosine kinase inhibitors (TKIs), the prognosis for patients with chronic myeloid leukemia (CML) has markedly improved, such that most patients diagnosed with CML can now expect to live with their disease rather than die from it. However, most patients will require long-term treatment, which has deleterious effects on health-related quality of life. We review recent literature on drug-related adverse effects, long-term medication adherence, limitations to fertility and pregnancy, effects on cognitive function, ability to work, financial toxicity, pediatric populations, and treatment discontinuation. While patients with CML are fortunate to have excellent therapies available to control their disease, many are unable to lead normal lives, which challenges the notion that research is no longer needed in CML. Curing CML, i.e., no detectable disease and no need for daily medications, should remain the ultimate goal.
