Spinal Cord Stimulation (SCS) is a treatment option for chronic pain patients. Spinal cord stimulation has been employed in the treatment of chronic pain for more than 30 years. The most common indication for SCS is the failed back syndrome with leg pain. Its indications have expanded beyond back and lower extremities pain to include axial low back pain, CRPS, mesenteric ischemia, peripheral neuropathy, limb ischemia, and refractory angina pectoris. The SCS has become a more versatile form of analgesia. The number of wound complications will surely rise in conjunction with the increasing number of devices being implanted. We describe a case of a well-differentiated squamous cell carcinoma occurring within the incision site of a recently implanted spinal cord stimulator early in the postoperative period. The patient developed a rapidly growing mass within the leads incision. The mass was confirmed to be squamous cell carcinoma by biopsy. The mass was excised under local anesthesia with appropriate margins. It was determined that the carcinoma did not extend below the dermis, and that there was no involvement of the underlying fascia. The device was tested for proper functioning, and the leads were thus left in place. While the development of skin malignancies in surgical wounds has been described in the literature, to our knowledge there have been no reports of a cutaneous neoplasm developing early in the postoperative period after spinal cord stimulator implantation. Key words: Spinal cord stimulator, CRPS type 1, squamous cell carcinoma

  The aim of this study was to observe the effectiveness of treatment with radical pinnectomy and investigate postoperative relapse cases in pinnal squamous cell carcinoma in cats. Twelve cats which were brought to surgery clinic of Istanbul University, Faculty of Veterinary Medicine were used. Biopsies were taken from the cases in which squamous cell carcinoma was suspected following anamnesis and the clinical examination of patients that were brought to our clinic. The patients were diagnosed on the basis of histopathological analysis of biopsy samples. Haemogram and biochemical blood analysis were performed and thoracic radiographs were taken as routine in cases that a decision was made to operate. After the area was prepared for operation radical pinnectomy or total external acoustic canal ablation along with radical pinnectomy were performed in the patients that were eligible for operation. Relapses seen in the postoperative period were re-operated with the techniques selected according to invasion status. Periodic controls of the patients were made after the operations and the cats were examined for relapse. In seven out of 12 cases, only squamous cell carcinoma; in three cases, actinic dermatitis actinic dermatitis in addition to squamous cell carcinoma, and in two cases, only actinic dermatitis lesions were detected. In the postoperative period, relapse was observed in the cases in which the squamous cell carcinoma lesion reached the lower half of the pinna or the external acoustic canal while relapse was not observed in cases with actinic dermatitis lesions or when the squamous cell carcinoma lesion was on the top part of the pinna. Relapse cases were re-operated using different operative techniques. It is concluded that performing radical pinnectomy on actinic dermatitis lesions detected on the pinna before development into squamous cell carcinoma, and removing the tumour according to its localization with radical pinnectomy or total external acoustic canal ablation alongside radical pinnectomy is the most reliable treatment option in terms of relapse in cases of pinnal squamous cell carcinoma.

AbstractBilateral venous thrombosis due to underlying malignancy is a rare entity. It is worthy to search for malignancy in patients of bilateral venous gangrene. Our patient presented with severe bilateral leg pain as a result of venous gangrene. There was associated left sided massive pleural effusion with scalp nodule. Fine needle aspiration cytology of scalp nodule revealed metastatic squamous cell carcinoma and fiber optic bronchoscopy guided biopsy from growth at left upper lobe bronchus confirmed the case as squamous cell carcinoma lung. It was rare for squamous cell carcinoma lung to present as bilateral venous gangrene with anticardiolipin antibody negative.

Abstract Background This study aimed to evaluate the wireless Freedom Spinal Cord Stimulator (WSCS) System for the treatment of chronic back and/or leg pain associated with failed back surgery syndrome (FBSS) refractory to standard medical treatment utilizing 10-kHz stimulation (high-frequency [HF]) in comparison with 10–1,500-Hz stimulation (low-frequency [LF]) waveforms. Methods Ninety-nine subjects were randomized in a 1:1 ratio to receive either HF or LF stimulation waveforms utilizing the same Freedom WSCS System. All subjects were implanted with two 8-electrode arrays in the exact same anatomical positions within the dorsal epidural spinal column, with the top electrode positioned at the T8 and T9 vertebrae levels, respectively, and the wireless receiver placed under the skin in a subcutaneous pocket. Results Seventy-two (HF: N = 38; LF: N = 34) subjects had completed the six-month follow-up after an initial 30-day trial period at the time of this report. For both the HF and LF arms, mean visual analog scale (VAS) scores for back and leg pain decreased significantly: 77% and 76%, respectively, for the HF arm and 64% and 64%, respectively, for the LF arm. In addition, most subjects experienced significant improvements in VAS, Oswestry Disability Index, European Quality of Life 5 Dimension questionnaire, Patient Global Impression of Change, and sleep duration. Conclusions These preliminary results demonstrate that WSCS devices can reduce FBSS chronic pain substantially with both LF and HF stimulation waveforms over a seven-month period (30-day trial period and six-month post-trial evaluation).

Background: Many studies have reported lead migration and breakage as complications of epidural spinal cord stimulation. In cases where rapid changes in physique such as those caused by pregnancy are expected, it is unclear whether extra consideration regarding possible adjustments and care to avoid complications such as lead breakage are required. Objective: This article presents a case in which spinal cord stimulation was used to manage these complications in a woman during the perinatal period. Design: Case report Setting: Pain management clinic Methods: The patient was a 36-year-old female, approximate weight of 100 pounds, and 5-foot 1 inch in height, whose chief complaint was lower back and bilateral leg pain. The pain could not be alleviated by conservative therapies such as nerve blockade, oral medications with non-steroidal anti-inflammatory drugs, antidepressants, anticonvulsants or physical therapy. A spinal cord stimulator was implanted at another facility, which relieved the pain. The patient subsequently had 2 vaginal births without any problems relating to the stimulation sites, and both infants were healthy. She experienced lead breakage after the third vaginal birth that led to the subsequent reimplantation procedure. Results: The patient had 2 subsequent vaginal births following the initial implantation with no problems related to the stimulation sites, and both infants were healthy. At age 34, following her third vaginal birth, the stimulator became ineffective and was removed. The withdrawn lead wire was found to be broken in 2 places. Limitations: A case report. Conclusion: Pregnancy following implantation of a spinal cord stimulator might result in lead breakage as abdominal girth increases. The present case exemplifies how pregnancy following implantation of a spinal cord stimulator might cause lead breakage as abdominal girth increases. Extra care is required to prevent lead breakage when anchors are fixed. Key words: spinal cord stimulator, reimplantation, lead breakage, pregnancy
