Percutaneous management of complications of tuberculous spondylodiscitis: short- to medium-term results.
ABSTRACT Psoas abscesses are the most frequent complication of tuberculosis with skeletal involvement. The aim of this paper is to report our experience with the systematic application of percutaneous drainage to tuberculous psoas abscesses.
Between January 1997 and December 2005, 23 patients (14 men and nine women; age range 21-48 years), after a previous study with computed tomography (CT) and/or magnetic resonance (MR) imaging, underwent percutaneous drainage of a tuberculous fluid collection in the psoas muscles. Follow-up consisted of monthly clinical and laboratory assessment, and plain chest radiography and spinal CT every 6-12 months.
Spondylodiscitis involved the thoracolumbar spine. Fluid collections were bilateral in 14 cases and communicating in ten of these. Maximum transverse diameter was 7 cm, whereas longitudinal diameter was 14 cm. Placement of the drainage catheter was successful in all cases, and the catheter was left in place for 5-36 (mean 18.4) days. Symptom regression occurred immediately after drainage of the fluid collection. The drainage procedure was curative in 100% of cases. Dislodgement of the drainage catheter occurred in two cases as a result of excessive traction during dressing removal.
A serious complication of bone tuberculosis, psoas abscesses, can be effectively treated by percutaneous drainage, leading to immediate pain resolution. The drainage catheter requires daily monitoring to identify when it can be safely removed without risk of recurrence.

ABSTRACT: To describe the clinical characteristics of patients with abscess on the psoas muscle (PA) and to identify the possible differences existing between pyogenic and tuberculous etiologies. A retrospective review of patients diagnosed of PA in one hospital was conducted (1983-2009). Two groups were established, that is pyogenic and tuberculous, and the clinical findings, analyses and evolution were compared. Thirty PA were included, 83% pyogenic and 17% tuberculous, average age 53 years. On 9 occasions, 30% were primary and on 21 occasions, 70% secondary (to skeletal pathology in 8, to urological in 8 and to gastrointestinal in 8). No clinical differences were observed between both groups. Pyogenic and tuberculous etiologies were differentiated analytically through leukocyte values (13,871 vs. 8,560/mm(3), p=0.018), hemoglobin (11 vs. 14 g/dL, p=0.008) and erythrocyte sedimentation rate (ESR) (108 vs. 17 mm/h, p<0.0001). Abscesses were diagnosed by computed tomography (CT) in 29 patients (97%) and by magnetic resonance in 1 (3%), both with a diagnostic sensitivity of 100%, as opposed to 50% for ultrasound scanning. Left laterality was less frequent in pyogenic abscesses (44% vs. 100%, p=0.031). The blood cultures were positive in 22% and abscess pus culture in 82%. Gram negative bacilli, Streptococcus spp. and S. aureus were the most frequent isolations. A total of 67% were drained: transcutaneously 50%, surgically 13% and both techniques 3%. Two patients died (7%), both with pyogenic abscess. Secondary pyogenic abscesses constitute the most frequent PA group. CT is the diagnostic procedure of choice. Leukocytosis, anemia, raised ESR and right laterality suggest pyogenic etiology. Transcutaneous drainage is substituting surgical drainage and also makes it possible to obtain diagnostic samples.Revista Clínica Española 12/2011; 211(11):572-8.

ABSTRACT: Transient neonatal pustular melanosis is mostly found in full-term black infants. It is a benign and self-limited disease, and the etiology is still unknown. We present a full-term female neonate with multiple vesiculopustular and pigmented macular lesions found immediately after her birth. A skin biopsy showed vesicles consisting of intracorneal and subcorneal aggregates of neutrophils, which is compatible with transient neonatal pustular melanosis. Although it is rare in Taiwan and Asian countries, transient neonatal pustular melanosis should always be considered when pustulosis is found in the neonatal period to prevent the use of unnecessary antibiotics. Dermatological consultation and histological confirmation are sometimes required for the final diagnosis.Pediatrics & Neonatology 12/2010; 51(6):356-8.

ABSTRACT: Percutaneous aspiration of abscesses under ultrasonography (USG) and computer tomography (CT) scan has been well described. With recurrence rate reported as high as 66%. The open drainage and percutaneous continuous drainage (PCD) has reduced the recurrence rate. The disadvantage of PCD under CT is radiation hazard and problems of asepsis. Hence a technique of clinically guided percutaneous continuous drainage of the psoas abscess without real-time imaging overcomes these problems. We describe clinically guided PCD of psoas abscess and its outcome. Twenty-nine patients with dorsolumbar spondylodiscitis without gross neural deficit with psoas abscess of size >5 cm were selected for PCD. It was done as a day care procedure under local anesthesia. Sequentially, aspiration followed by guide pin-guided trocar and catheter insertion was done without image guidance. Culture sensitivity was done and chemotherapy initiated and catheter kept till the drainage was <10 ml for 48 hours. Outcome assessment was done with relief of pain, successful abscess drainage and ODI (Oswestry Disability Index) score at 2 years. PCD was successful in all cases. Back and radicular pain improved in all cases. Average procedure time was 24.30 minutes, drain output was 234.40 ml, and the drainage duration was 7.90 days. One patient required surgical stabilisation due to progression of the spondylodiscitis resulting in instability inspite of successful drainage of abscess. Problems with the procedure were noticed in six patients. Multiple attempts (n = 2), persistent discharge (n = 1) for 2 weeks, blocked catheter (n = 2) and catheter pull out (n = 1) occurred with no effect on the outcome. The average ODI score improved from 62.47 to 5.51 at 2 years. Clinically guided PCD is an efficient, safe and easy procedure in drainage of psoas abscess.Indian Journal of Orthopaedics 03/2014; 48(1):67-73. DOI:10.4103/0019-5413.125506 · 0.62 Impact Factor
