RESUMO
Acanthosis Nigricans is considered to be a skin marker of insulin resistance and atherosclerosis. It is rarely reported in cases of insulinoma where there is marked hyperinsulinaemia. We report two cases of insulinoma with acanthosis nigricans which regressed, concomitant with significant weight loss and reduction in blood pressure following surgical resection. This strengthens the hypothesis that hyperinsulinaemia is responsible for Acanthosis nigricans and atherosclerotic risk factors.
RESUMO
BACKGROUND: Pain is a common symptom for patients with cancer. Hospice and Palliative Medicine (HPM) physicians are expected to be experts in both pharmacologic and non-pharmacologic treatment of pain for this patient population. Insufficient knowledge of non-pharmacologic, interventional approaches to pain management is a barrier to providing optimal care. This study assesses the feasibility and effectiveness of an interventional pain management curriculum on HPM fellow knowledge at a single institution. OBJECTIVES: The primary objective was to implement an interventional pain management curriculum for HPM fellows' and secondly to measure its effects on their knowledge and confidence in interventional pain management approaches. METHODS: We executed an interventional pain management curriculum for HPM fellows. The curriculum consisted of 6 fifty-minute virtual lectures. Anonymous pre- and post-curriculum surveys were used to assess curricular impact. RESULTS: Post-course surveys showed a significant increase in HPM fellows' knowledge and confidence in interventional pain management techniques. CONCLUSIONS: An interventional pain management curriculum for HPM fellows is a feasible and promising intervention to significantly impact fellows' knowledge and confidence in non-pharmacologic treatment of cancer pain.
RESUMO
ABSTRACT: Reverse total shoulder arthroplasty (rTSA) is an effective procedure to improve shoulder pain, range of motion, and function for a variety of conditions, including glenohumeral osteoarthritis and rotator cuff arthropathy. However, up to 22% of patients have persistent shoulder pain 12 to 24 months following rTSA, even in the absence of surgical complications. Currently, there are no widely accepted non-pharmacological treatments for persistent postoperative pain after rTSA. This case report details the successful management of a 64-year-old woman with chronic postoperative shoulder pain following rTSA. She was treated with single-lead percutaneous peripheral nerve stimulation to the right axillary nerve for eight weeks with 12 Hz motor-level stimulation. She demonstrated improvement in shoulder flexion active range of motion, shoulder flexion strength, and shoulder abduction strength. Her Shoulder Pain and Disability Index total score improved from 26.93% to 8.46% one year following treatment. She reported an overall Global Rating of Change of +7 one year following treatment. This case's success demonstrates that short term peripheral nerve stimulation may provide long-term improvement of persistent post-operative pain and dysfunction in patients with painful rTSA.
RESUMO
ABSTRACT: Total hip arthroplasty is an effective procedure to improve pain, range of motion, and function for a variety of conditions, including osteoarthritis and posttraumatic arthritis. Up to 28% of patients had persistent pain at the surgical site 12-18 mos after total hip arthroplasty, even in the absence of surgical complications. Currently, there are no widely accepted nonpharmacological treatments for persistent postoperative pain for total hip arthroplasty. This case report details the successful management of a 53-yr-old man with chronic pain and weakness after posttraumatic total hip arthroplasty. He was initially treated with a single-lead percutaneous peripheral nerve stimulator near the right femoral nerve for 4 weeks with 100-Hz frequency sensory-level parameters. Four weeks after implantation, the frequency was changed to 12 Hz with a goal of motor-level stimulation. During the after 3-week time period, his hip flexion strength improved from 10.36 kg to 23.04 kg. His Lower Extremity Functional Scale improved from 35/80 (43.75%) to 54/80 (67.5%) within a 5-wk time period. This case's success demonstrates how peripheral nerve stimulation may help improve postoperative persistent pain and weakness in many patients, including those with posttraumatic arthroplasty.

OBJECTIVE: To summarize the recommendations on the interventional management of subacute and chronic nonradicular low back pain (LBP) from the 21 quality-appraised clinical practice guidelines (CPGs) identified in a previously published paper: "Quality of Clinical Practice Guidelines on Interventional Management of Low Back Pain: A Systematic Review." By disseminating this information, we aimed to facilitate the implementation of these recommendations into clinical practice. TYPE: Systematic Review LITERATURE SURVEY: Electronic bibliographic databases, guideline databases, and gray literature were searched from January 2016 to January 2020 to identify CPGs that met study criteria. METHODOLOGY: A total of 21 CPGs were quality appraised and interventional management recommendations were extracted and organized into several treatment categories including epidural steroid injections, radiofrequency procedures (RF), facet injections, sacroiliac injections, and prolotherapy. Within each treatment category, the recommendations were organized based on two factors: quality of CPG and strength of recommendation. SYNTHESIS: Overall, there was no consistency in recommendations for or against any interventional procedure, even when accounting for the quality of the CPG. In all of the CPGs reviewed, the most common strength of recommendation was weakly for. The second, third, and fourth most common strength of recommendations were inconclusive, weakly against, and strongly against, respectively, and the least common was strongly for. The treatment categories with the greatest number of recommendations were RF procedures (most common strength of recommendation was weakly for) and facet procedures. Among the high-quality CPGs, the most common strength of recommendation was inconclusive. CONCLUSIONS: Most of the interventional management recommendations for management of nonradicular LBP in the 21 CPGs appraised in this review were either weakly for, weakly against, or inconclusive, with several recommendations within each treatment category contradicting each other. Appraisal of Guidelines for Research & Evaluation Instrument quality appraisals of CPGs on interventional management of LBP were of unclear utility in guiding clinical implementation.

OBJECTIVE: To appraise the quality of low back pain (LBP) clinical practice guidelines (CPG) that include interventional management recommendations and to associate their quality with characteristics including publication year and creating organization. TYPE: Systematic Review. LITERATURE SURVEY: LBP (subacute or chronic) CPGs in English (symptom based, governmental or professional society created, January 1990-May 2020) were found using MEDLINE, EMBASE, CINAHL, Ortho Guidelines, CPG Infobase, ECRI, Guidelines International Network, NICE, and SIGN. METHODOLOGY: In this third order systematic review, search results were deduplicated, title and abstract screened by two independent reviewers, and full texts reviewed by four reviewers. Discrepancies were resolved by a third reviewer. Resulted CPGs were appraised using the Appraisal of Guidelines for Research and Evaluation (AGREE II) Tool by four appraisers each. Association of their quality with creating organization, geographical region, and year of creation was calculated. SYNTHESIS: Seven hundred fourteen screened documents resulted in 21 final CPGs. On appraisal, average overall CPG quality was 5.2 (range 2.5-6.75). Domain 5 (applicability) had the lowest average (44%) and domain 4 (clarity of presentation) had the highest average score (82%). For overall recommendation, 16 received "yes" or "yes with modifications," six received unanimous "yes" and two unanimous "no" votes. The interrater agreement of domain scoring was excellent (0.8-1.0; p < .001). There was no association found between quality of CPG and (1) year of publication (R2 = 0.0006), (2) whether the CPG was updated or new (p = .17), and (3) region of publication (p = .37). CONCLUSIONS: The majority of the 21 CPGs identified in this systematic review were of high quality, but overall quality and recommendation ratings were variable. The quality of appraised CPGs showed no association with their characteristics. Some domains such as "applicability" scored uniformly lower, revealing opportunity for improvement in future CPG development. LBP CPGs should be scrutinized before adopting their recommendations.

BACKGROUND: Isolated hypogonadotropic hypogonadism (IHH) is a rare disorder being classified as Kallmann syndrome (KS). The present study was conducted to study the genotype and relative proportion of different genetic mutations in IHH and to assess its correlation with phenotype. METHODS: Eleven consecutive subjects presenting to the Department of Endocrinology were retrospectively analyzed during May 2017 to December 2018 with IHH. Phenotypic features and hormonal studies were analyzed along with clinical exome by targeted gene sequencing (Next generation sequencing). Thirty-nine relevant genes were tested in the analysis. RESULTS: Of the 11 patients studied, five had KS and six had nIHH. At diagnosis, mean chronological age was 25 years. There were associated anomalies in KS group including bimanual synkinesia (n=2), unilateral renal agenesis (n=1) and submucosal cleft palate (n=1). Absence or hypoplasia of the olfactory bulb/sulci was found in 4/5 patients with KS. Genetic mutations in KAL1, CHD7, FGFR1, GNRHR, PROKR2, HS6ST1 genes were found in nine of the eleven subjects. Of the five subjects with KS, two had mutations in KAL1 gene. Two siblings who had bimanual synkinesia had CHD7 mutation. The genotype of nIHH subjects (n=6) was more heterogeneous. CONCLUSION: This study analyzed the clinical, endocrinological, and genetic features in IHH patients. Detectable genetic mutations were seen in a large proportion of cases. A considerable heterogeneity was seen in the genotype with new variants detected. A definite correlation of phenotype-genotype was not possible, and significant overlap was seen between CHD7 and KAl1, and FGFR1 phenotypes.
RESUMO
We report a case of a 5-year-old boy presenting to us with short stature. He was born of consanguineous parentage and was small for gestational age. He had severe short stature, with height Z score of -6.2 SD Score, markedly delayed skeletal age, low level of insulin-like growth factor 1, unstimulated growth hormone and hypoplastic anterior pituitary gland on MRI. He was advised growth hormone (GH) replacement at 2 years of age, but he did not receive it . Later on, he developed photosensitive telangiectatic lesions over face and required multiple hospital admissions for recurrent systemic infections. Genetic analysis confirmed the diagnosis of Bloom's syndrome. The present case report illustrates the need for high vigilance for conditions like Bloom's syndrome in growth hormone deficiency (GHD), in whom GH treatment could potentially be harmful. Bloom's syndrome with GHD is an exceedingly rare association.
