Low back pain education and short term quality of life: a randomized trial

Background  

Different interventions can reduce the burden of the chronic low back pain. One example is the use of a 'Back School Programme'. This is a brief therapy that uses a health education method to empower participants through a procedure of assessment, education and skill development. This study aimed to evaluate to what extent the programme could improve quality of life in those who suffer from the condition.     

Laser treatment of recurrent urethral condylomata acuminata in men

Fifty-six consecutive men with recurrent condylomata acuminata of the urethra and possibly also of the external genitalia were treated with carbon dioxide or ND: YAG laser or both. In all patients previous conservative treatments had failed. Half the patients responded completely to a single treatment and 86% to a maximum of three treatments. No important side effects were encountered, and the cosmetic results have been excellent.     

Hypercalcemia After Cosmetic Oil Injections: Unraveling Etiology,Pathogenesis, and Severity

Intramuscular injections of paraffin oil can cause foreign body granuloma formation and hypercalcemia. Macrophages with the ability to produce high levels of 1,25(OH)₂D₃ may induce the mineral disturbance, but no major series of patients have been published to date. Here, medical history, physical evaluation, biochemical, and urinary analysis for calcium homeostasis were obtained from 88 males, who 6 years previously had injected paraffin or synthol oil into skeletal muscle. Moreover, granuloma tissue from three men was cultured for 48 hours ex vivo to determine 1,25(OH)₂D₃ production supported by qPCR and immunohistochemistry of vitamin D metabolism and immune cell populations after treatment with 14 different drugs. The 88 men were stratified into men with hypercalcemia (34%), whereas normocalcemic men were separated into men with either normal (42%) or suppressed parathyroid hormone (PTH) (24%). All men had high calcium excretion, and nephrolithiasis was found in 48% of hypercalcemic men, 22% of normocalcemic men with normal PTH, and 47% of normocalcemic men with suppressed PTH. Risk factors for developing hypercalcemia were oil volume injected, injection of heated oil, high serum interleukin-2 receptor levels, and high urine calcium. High 1,25(OH)₂D₃/25OHD ratio, calcium excretion, and low PTH was associated with nephrolithiasis. The vitamin D activating enzyme CYP27B1 was markedly expressed in granuloma tissue, and 1,25(OH)₂D₃ was released in concentrations corresponding to 40% to 50% of the production by human kidney specimens. Dexamethasone, ketoconazole, and ciclosporin significantly suppressed granulomatous production of 1,25(OH)₂D₃. In conclusion, this study shows that injection of large oil volumes alters calcium homeostasis and increases the risk of nephrolithiasis. Hypercalciuria is an early sign of disease, and high granulomatous 1,25(OH)₂D₃ production is part of the cause. Prospective clinical trials are needed to determine if ciclosporin, ketoconazole, or other drugs can be used as prednisolone-sparing treatment. © 2020 American Society for Bone and Mineral Research (ASBMR).     

Index of clinical consequences of untreated dental caries (pufa) in primary dentition of children from north-east Poland

PurposeThe purpose of this study was to evaluate the prevalence and experience of clinical consequences of untreated dental caries in primary dentition in 5 and 7 year-old children from north-east Poland and to find whether there is a correlation between dmft and pufa indices.Material/MethodsTwo hundred fifteen children aged 5 and 7 years living in the Podlaskie region were examined in the course of the Polish National Oral Health Survey 2011. Caries prevalence and experience in primary dentition was evaluated according to WHO criteria (dmft index). The clinical consequences of untreated dental caries were assessed by pufa index.ResultsThe dmft index was 5.56±4.45 in 5-years-old children and 6.69±3.14 in 7-years-olds. The prevalence/experience of pufa index was 43.4%/2.20±3.43 and 72.4%/2.44±2.22, respectively. Children living in rural areas presented a worse dental condition. A statistical analysis revealed a strong relation between dmft and pufa in both age groups.ConclusionThe present study revealed negligence in the dental treatment of children from north-east Poland resulting in the high prevalence and experience of the pufa index in primary dentition. This index is a valuable measurement tool to record the clinical consequences of untreated dental caries.     

Treatment of undifferentiated embryonal sarcoma of the liver in children—single center experience

Background

Undifferentiated embryonal sarcoma of the liver (UESL) represents less than 5% of all malignant hepatic tumors in childhood. It is considered an aggressive neoplasm with an unfavorable prognosis. The aim of this paper is to present a single center experience in the treatment of children with UESL.

Materials and methods

Ten children with UESL were treated between 1981 and 2012. Age at diagnosis ranged from 4 months to 17 years (median age, 6 years and 9 months). Surgery after neoadjuvant chemotherapy (CHT) was performed in 7 patients, and in 3 patients primary surgery was done. Adjuvant chemotherapy was administered in all 10 patients (CYVADIC, CAV, CAV/ETIF/IF + ADM, CDDP/PLADO). Right hemihepatectomy was performed in 1 patient, extended right hemihepatectomy in 6, and partial resection of the right lobe (segments V-VI, segment V) in 2 patients. One patient with unresectable tumor affecting both lobes was listed for liver transplantation (LTx).

Results

Follow-up from diagnosis ranged from 50 to 222 months (mean 138 months). Among 9 patients treated with partial liver resection, distant metastases/local recurrence was not observed in any, and disease-free survival in this group is 100% (9 patients alive). The patient that underwent liver transplantation died of multiorgan failure 4 months postoperatively.However, this patient was misdiagnosed as having hepatoblastoma (HBL) and received PLADO chemotherapy. The overall survival rate is 90%.

Conclusion

Excellent results with long-term survival can be achieved in children with UESL with conventional therapy, including a combination of neoadjuvant and adjuvant chemotherapy and surgery, even in large extensively growing tumors.
