Granulomatous spondylodiscitis: A case series with focus on histopathological features.

Objective: To report a series of Granulomatous Spondylodiscitis (GS) with focus on the histopathological features of the different forms of GS.Design: Case series.Setting: Pathology department of Charles Nicolle's Hospital of TunisiaParticipants: This study included 57 patients diagnosed with GS. There were 44 (77.2%) female patients and 13 (22.8%) male patients (sex ratio = 0.28).Intervention: Not applicable.Outcome measures: Clinical, microbiological and histopathological features were assessed in this study.Results: Fifty-seven patients with GS were enrolled: 51 tuberculous spondylodiscitis (TS), 2 fungal spondylodiscitis (FS), 3 brucellar spondylodiscitis (BS) and 1 case of sarcoidosis. Granulomas with necrosis were seen in 38 (66.6%) cases: 36 TS and 2 FS, while granulomas without necrosis were observed in the remaining 19 cases: 15 TS, 3 BS and 1 sarcoidosis. In all cases of TS, granulomas were epithelioid type, associated with histiocytic type granulomas in 7 cases. Caseous necrosis was seen in 35 cases of TS and suppurative granuloma in one case. The 3 cases of BS exhibited non-necrotizing and histiocytic type granulomas. The 2 cases of FS showed histiocytic, epithelioid and necrotizing granulomas. Necrosis was mixed: suppurative and caseous in both cases of FS. Sarcoidosis was characterized with epithelioid type granulomas without necrosis.Conclusion: Granuloma with caseous necrosis is highly suggestive of TS but does not rule out FS. Certain fungi can exhibit this type of necrosis as do tuberculosis species. Suppurative inflammation, although rare in TS, does exist. Histiocytic type granuloma without necrosis is suggestive of brucellosis.

The Value of Histology in the Diagnosis of Tuberculous Spondylodiscitis.

BACKGROUND: Tuberculous spondylodiscitis (TS) is the most common form of musculoskeletal tuberculosis. Currently, histology is widely used to distinguish tuberculous from nontuberculous disease. OBJECTIVES: The aim of the present study was to assess the accuracy of histology compared with bacteriology in the diagnosis of TS. METHODS: This is a single-center case series carried out from January 2014 to February 2018 in a pathology department. It included 121 discovertebral biopsies of infective spondylodiscitis. The measures of diagnostic accuracy of histology were determined taking bacteriology as criterion standard. RESULTS: Among the 121 cases, 55 (45.4%) were diagnosed as TS by histological and/or bacteriological findings, 17 (30.9%) were classified as definite TS by bacteriology, and the remaining 38 (69.1%) had positive histology and negative bacteriology. There were 2 false-negatives, which histologically displayed suppuration without granuloma, and 3 false-positives; in one case, histology displayed granulomas without necrosis and culture isolated Brucella. In the 2 others, histology revealed granulomas with caseous-like necrosis and microbiology isolated fungal species. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of histology in the diagnosis of TS were 88.2%, 93.4%, 83.3%, 95.5%, and 92%, respectively. CONCLUSIONS: Histology is proved to be an accurate diagnostic tool in TS. Suppurative forms of TS without granuloma are rare and represent the main cause of false-negative histology. Suggestive histology of TS does not rule out fungal and brucellar spondylodiscitis. Caseous necrosis is not pathognomonic of tuberculosis. Fungal infection can also exhibit such type of necrosis.

[Epidemio-clinical features of genital tuberculosis among Tunisian women: a series of 47 cases]. / Caractéristiques épidémio-cliniques de la tuberculose génitale chez la femme tunisienne: une série de 47 cas.

This study aimed to identify the epidemio-clinic, diagnostic, therapeutic and evolutionary features of genital tuberculosis (GT) among Tunisian women. We conducted a retrospective, descriptive study in the Department of Infectious Diseases at the La Rabta Hospital, Tunisia, over a period of 15 and a half years (January 2000 - June 2014). All patients hospitalized for genital TB were included in the study. The study focused on 47 cases. The average age of patients was 42.2 years. Eighteen women were from rural areas. Tuberculous contact was found in five cases. In all cases, the onset was insidious. Twenty-three patients showed one or several signs of TB infection. Tuberculin intradermal reaction (IDR) test was performed in 35 women (74.8%), it was positive in 26 cases (74%). Thirty-nine patients (83%) had undergone radiological examination using abdomino-pelvis ultrasound and/or CT scan. Diagnostic coelioscopy was performed in 37 cases (75.5%). Anatomopathological examination helped to confirm the diagnosis of GT in 42 cases (89.3%), showing epithelioid and giant-cell granuloma. We identified 21 cases of isolated GT, the remaining 26 cases had peritoneal involvement. All patients received specific antibiotic therapy combining isoniazid, rifampicin, pyrazinamide and ethamubutol with an average treatment duration of 12 months. No patient received corticosteroids or secondary surgery. Patients' outcome was favorable in 39 cases, 8 patients were lost to follow-up. Genital tuberculosis is rare, representing only 0.5% of extra-pulmonary tuberculosis, but it accounts for a high prevalence of clinical polymorphism. Diagnostic confirmation is difficult and it is based on bacteriological and/or histological examinations. Diagnosis should be suspected in patients with chronic abdominopelvic symptoms, in women with infertility associated with suggestive epidemioclinical manifestations.

Paradoxical reaction associated with cervical lymph node tuberculosis: predictive factors and therapeutic management.

OBJECTIVES: The aims of this study were to determine predictive factors of paradoxical reaction in patients with cervical lymph node tuberculosis (TB) and to discuss the therapeutic management of this condition. MATERIALS AND METHODS: A retrospective study was performed of 501 patients managed for cervical lymph node TB over a period of 12 years (from January 2000 to December 2011). Statistical data were analyzed using IBM SPSS Statistics version 20.0. RESULTS: Paradoxical reaction occurred in 67 patients (13.4%), with a median delay to onset after starting TB treatment of 7 months. Lymph node size ≥3cm and associated extra-lymph node TB were independently associated with paradoxical reaction. Treatment consisted of surgical excision (71.6%), restarting quadruple therapy (10.4%), reintroduction of ethambutol (23.8%), and addition of ciprofloxacin (20.8%); steroids were given in two cases . All patients recovered after an average treatment duration of 14.91±7.03 months. CONCLUSION: The occurrence of paradoxical reaction in cervical lymph node TB seems to be predicted by associated extra-lymph node TB and a swelling size ≥3cm. The treatment of paradoxical reaction remains unclear and more randomized trials are necessary to improve its management.

[Upper urinary tract infections in adults: about 261 episodes]. / Infections urinaires hautes de l'adulte: à propos de 261 épisodes.

BACKGROUND: Upper urinary tract infections are frequent. Escherichia coli is the main pathogen identified from community acquired infections. AIM: We aim to study epidemiologic, clinical and bacterial features of this infection. METHODS: We identified 261 episodes that occurred in 241 patients. They were 213 females and 48 males aged of 48.75 years. Enterobacteriaceae were the main pathogens isolated in 93.5%: E. coli in 73.3% and Klebsiella pneumoniae in 15.3%. E. coli sensitivity was of 30% for amoxicillin, 98% for cefotaxim, 96% for gentamicin, 90% for ciprofloxacin and 56% for co-trimoxazole. Anterior antibiotic use was associated with low E. coli sensitivity mainly with fluoroquinolones (96 vs 77%) and co-trimoxazole (62 vs 43%). This enhances the role of antibiotic pressure on the resistance emergence. CONCLUSION: the reasonable use of antibiotics is necessary to limit resistance extent.
