Prostate cancer is the most commonly diagnosed visceral cancer in the United States. A majority of cases exhibit an insidious course and nonaggressive tumor behavior. Prostate cancer can manifest as lesions which remain localized, regionally invading or metastasize to lymph nodes, bones, and lungs. Here, we report a unique case of metastatic prostate cancer to the right upper mediastinum, presenting as a paravertebral mass within 2 years of initial tissue diagnosis. Paravertebral spread has not been described for prostate cancer, and herein, we discuss the clinical presentation, diagnostic workup, and possible therapeutic options available in light of the literature...

INTRODUCTION: Open chest surgery (thoracotomy) is considered the most painful of surgical procedures. Forceful wound retraction, costochondral dislocation, posterior costovertebral ligament disruption, intercostal nerve trauma and wound movement during respiration combine to produce an acute, severe postoperative pain insult and persistent chronic pain many months after surgery is common. Three recent systematic reviews conclude that unilateral continuous paravertebral blockade (PVB) provides analgesia at least equivalent to thoracic epidural blockade (TEB) in the postoperative period, has a lower failure rate, and symptom relief that lasted months...

OBJECTIVE: We evaluated the analgesic feasibility of paralaminar in-plane (PL) approach for ultrasound-guided thoracic paravertebral block (USG-TPVB). As the needle trajectory was expected to be closely affected by the distance from the skin to the lamina-transverse process junction (LTPJ), we examined the correlativity between them on computed tomography (CT) or ultrasonography. METHODS: Thirty-two patients undergoing thoracotomy were recruited. We measured the distances between the skin and LTPJ using preoperative CT (S-L) and procedural ultrasonography (US-L)...

INTRODUCTION: Early and accurate identification of recurrences in patients with aggressive paraganglioma (PGL) poses significant challenges. Moreover, the most appropriate therapeutic strategy for recurrent PGL remains to be established. RESULTS: We report the case of 52-year-old man with a history of recurrent, sporadic, left retroperitoneal PGL that relapsed twice (at eight and nine years after the first surgical intervention). At the time of the second recurrence, 2-deoxy-2-[fluorine-18]fluoro-D-glucose (FDG) positron emission tomography/computed tomography (PET/CT) demonstrated a pathologically increased tracer uptake in multiple nodular lesions (10-15 mm in size) located close to the remnant of the left renal pedicle and in the left lombar paravertebral region...

Quadratus lumborum block has recently been described as an effective and long-lasting analgesic strategy for various abdominal operations, including gynaecological laparoscopy. Despite evidence that the analgesic effect is mediated by indirect paravertebral block and that local anaesthetic spreads to the lumbar paravertebral space, there have been no reports to date of lower limb motor weakness. We present a patient with unilateral hip flexion and knee extension weakness leading to unplanned overnight admission following lateral quadratus lumborum block with 20 ml levobupivacaine 0...

Retroperitoneal lymphnode dissection (RPLND) is a fundamental surgical step in the treatment of testicular cancer. Nowadays primary RPLND has partially lost its role in favour of active surveillance (for low risk stage I disease) and short cycle chemotherapy in non-seminomatous germ cell tumour (NSGCT). Conversely, postchemotherapy-RPLND (PC-RPLND) remains the standard treatment for residual masses after chemotherapy. In consideration of curability rate of testicular cancer and the life expectancy of testicular cancer survivors the identification and the prevention of andrological complications became fundamental...

The incidence of TB in children in Germany has been on a rise since 2008, especially among foreign-born individuals. With rapidly increasing numbers of refugees from the numerous areas of conflict, this increase in incidence is not expected to halt, neither in Germany nor in Europe in general. We report a case of insufficient tracking in a 16-year-old unaccompanied refugee minor from Somalia who had a positive interferon γ release assay on arrival in Germany. No actions were undertaken, until 6 months later, an X-ray showed prominent hilar enlargement...

Thoracic paravertebral nerve blocks (PVNBs) provide excellent analgesia for many surgeries. The primary aim was to estimate the complication rate, and secondary aims were to provide information on the potential clinical application of PVNBs. Data on 2390 PVNBs were collected. A total of 625 catheters were performed on 468 patients, and 1765 single-injection PVNBs were performed on 403 patients. There was 1 case of local anesthetic systemic toxicity for a major complication rate of 1 per 2390 PVNBs. The minor complication rate was 13...

OBJECTIVES: Patients with head and neck cancer (HNC) have a higher risk of malnutrition and sarcopenia, which is associated with adverse clinical outcome. As abdominal CT-imaging is often used to detect sarcopenia, such scans are rarely available in HNC patients, possibly explaining why no studies investigate the effect of sarcopenia in this population. We correlated skeletal muscle mass assessed on head and neck CT-scans with abdominal CT-imaging. METHODS: Head and neck, and abdominal CT-scans of trauma (n=51) and HNC-patients (n=52) were retrospectively analyzed...

BACKGROUND: Postural headaches are commonly associated with spontaneous intracranial hypotension and cerebrospinal fluid (CSF) leakage from the spine. A subarachnoid-pleural fistula (SPF) is a very rare and serious type of CSF fistula that has mostly been reported following traumatic causes. CASE REPORT: Here, the case of a 36-year-old woman who suffered from postural headaches after chiropractic manipulation of her neck was reported. Brain and spinal magnetic resonance (MR) imaging showed brain sagging, a C7-T1 dural defect, and overt CSF leakage...

Hemispheric lateralization of pain processing was reported with overactivation of the right frontal lobe. Specifically in chronic low back pain (CLBP), functional changes in the left primary motor cortex (M1) with impaired anticipatory postural activation (APA) of trunk muscles have been observed. Given the connections between frontal and M1 areas for motor planning, it is hypothesized that the pain side could differently influence M1 function and APA of paravertebral multifidus (MF) muscles. This study aimed at testing whether people with right- versus left-sided CLBP showed different M1 excitability and APA...

OBJECTIVES: The addition of a perioperative continuous paravertebral nerve block (cPVB) to a single-injection thoracic paravertebral nerve block (tPVB) has demonstrated improved analgesia in breast surgery. However, its use following isolated post-mastectomy reconstruction using a latissimus dorsi flap (LDF) has not previously been examined. METHODS: We performed a retrospective review of patients who underwent salvage breast reconstruction with a unilateral LDF by a single surgeon...

Kinsbourne syndrome is a rare neurological paraneoplastic syndrome associated with neuroblastic tumors. There are very few literatures on its anesthetic management and interaction with anesthetic agents. The epileptogenic potential of certain anesthetic agents such as ketamine, etomidate, and meperidine might trigger opsoclonus and myoclonus and have an impact on the long-term neurological outcome. The objective of this case report is to discuss the safety of anesthetic agents and their relationship in a patient with Kinsbourne syndrome...

The lateral costotransverse ligament, a short band that stabilizes the costovertebral joint, is found in close proximity to the dorsal root ganglion. This ligament is an important surgical landmark during tumor resections or nerve blocks in the paravertebral space. The purpose of this study was to quantitatively and qualitatively describe the morphology of the lateral costotransverse ligament and its relation to the dorsal root ganglion at all levels of the thoracic spine. The thoracic spines of eight embalmed cadavers were dissected bilaterally...

BACKGROUND AND OBJECTIVES: Paravertebral block placement was the main anesthetic technique for modified radical mastectomy in our hospital until February 2014, when its combination with blocks targeting the pectoral musculature was initiated. We compared the analgesic effects of paravertebral blocks with or without blocks targeting the pectoral musculature for modified radical mastectomy. METHODS: We retrospectively collected data from a single surgeon and anesthesiologist from June 1, 2012, to May 31, 2015...
