Tuberculosis of hip: A current concept review

3D-printed Personalized Porous Acetabular Component to Reconstruct Extensive Acetabular Bone Defects in Primary Hip Arthroplasty

OBJECTIVE

Management of extensive acetabular bone defects in total hip arthroplasty (THA) remains challenging. This study aims to investigate the feasibility and preliminary outcomes of 3D-printed personalized porous acetabular components for the reconstruction of acetabular defects in primary THA.

METHODS

This retrospective study involved seven patients who received 3D-printed acetabular components in primary THA between July 2018 and March 2021. Preoperatively, acetabular bone defects were evaluated by referencing the Paprosky classification. There were two "Paprosky type IIIA" defects and five "Paprosky type IIIB" defects. The acetabular components were custom-made for each patient to reconstruct the extensive acetabular defects. The hip function was assessed according to the Harris hip score (HHS). Clinical and radiographic outcomes were assessed.

RESULTS

The average follow-up period was 40 months, ranging from 26 to 57 months. There were no patients lost to follow-up. The HHS improved from 44 (range: 33-53) before the operation to 88 (range: 79-93) at the final follow-up. Postoperative X-rays showed that the 3D-printed personalized components were properly fitted with the acetabulum. The average center of rotation (COR) discrepancy was 2.3 mm horizontally and 2.1 mm vertically, respectively. Tomosynthesis-Shimadzu metal artifact reduction technology images showed that the implant was in close contact with the host bone. Moreover, no complications were observed during the follow-up period, including loosening, dislocation, or component protrusion.

CONCLUSION

The implantation of 3D-printed personalized acetabular components showed accurate reconstruction, stable mechanical support, and favorable function at short-term follow-up. This may be a viable alternative method for reconstructing extensive acetabular defects in THA.

Multifocal Skeletal Tuberculosis - A Case Report

Introduction

Tuberculosis (TB) remains a pervasive infectious disease, and extrapulmonary manifestations account for a significant proportion of cases. Skeletal involvement is observed in about 10% of extrapulmonary TB instances. While spinal TB is relatively common, sacroiliac (SI) joint TB is a rare occurrence, particularly in immunocompetent individuals.

Case Report

This case report discusses an unusual presentation in a 19-year-old immunocompetent lady where the spine, acetabulum, and SI joint were concurrently affected. The patient, initially undergoing alternative medicine, exhibited severe pain, weight loss, and restricted mobility. Radiological evaluations, including X-rays and magnetic resonance imaging, revealed extensive vertebral and pelvic destruction with abscess formation. Surgical debridement and stabilization, alongside antitubercular treatment, led to significant improvement.

Conclusion

This case emphasizes the challenges in diagnosing multifocal skeletal TB, highlights the importance of early intervention, and underscores the impact of alternative medicine on treatment delays. A multidisciplinary approach involving histopathological and microbiological examinations is crucial for optimal management.

Tuberculosis of the Iliac Bone and Acetabulum With Iliopsoas, Obturator Internus, and Obturator Externus Abscesses in an Immunocompetent Indian Female: An Extremely Rare Case

Skeletal tuberculosis is a rare form of extrapulmonary tuberculosis. Due to non-specific clinical features, these cases are often diagnosed very late, ultimately affecting treatment outcomes. The present case is a very rare case of tuberculosis of the iliac bone and acetabulum with iliopsoas, obturator internus, and obturator externus abscesses in an Indian female. She reported pain in her right hip and a limp. It was a difficult diagnosis, especially due to the rare involvement of bones and muscles in the absence of any lesions in the lungs. Nevertheless, the diagnosis was achieved by a detailed radiometric and laboratory workup. She was initiated on antituberculous treatment per her weight for 12 months.

Tuberculous Septic Arthritis of the Hip Following the Incision and Drainage of a Groin Abscess: A Case Report

Tuberculosis of the hip is a relatively rare type of septic arthritis that is seldom seen in the developed world today. While pyogenic septic arthritis may present with clear features that help in early diagnosis and treatment, many of these features are absent or overlap significantly with tuberculous arthritis, making the diagnosis a clinical challenge. Here, we present a case of tuberculous septic arthritis seen in our clinic following the surgical incision and drainage of a groin abscess with minimal hip symptoms. We discuss the therapeutic approach for the patient and briefly review other reported cases of tuberculous septic arthritis in the literature.

Functional outcome of total hip arthroplasty in tubercular hip arthritis: A prospective study

Background

Total hip arthroplasty (THA) is a well-established procedure to cure tubercular hip arthritis in patients with healed tuberculosis while its role in active tuberculosis is still debatable. The aim of the study is to investigate the functional outcomes of THA in active tuberculosis with advanced hip arthritis. The reactivation of tuberculosis and complications postoperatively has also been assessed.

Materials and methods

The current open-ended prospective cohort study was carried out at a tertiary center from 2018 to 2020. Twenty patients of active tubercular hip arthritis (8 females and 12 males) were taken with a follow-up period ranging from 1 year to 3 years, with a mean of 14 months.Biochemical investigations were done both preoperatively and postoperatively. Preoperative anti-tubercular therapy (ATT) regimen was administered, as per standard norms, to patients for a minimum period of 6 weeks, and postoperatively for 6 months-12 months. Postero-lateral and Hardinge approaches were employed in all cases. Clinical and radiological parameters were assessed and functional outcomes were evaluated using the Harris Hip score (HHS).

Results

The mean age of patients was 37.6 ± 11.38 years. Biochemical parameters were also found to improve postoperatively (p < 0.0001). The mean flexion, extension, abduction, external and internal rotation were found to increase postoperatively (p < 0.001). The mean flexion deformity in the preoperative period was 12.35 ± 4.716, whereas none of the patients had flexion deformities post operatively. The mean shortening was 2.12 ± 0.60 and 1 ± 0 at preoperative and postoperative respectively. The Total hip arthroplasty implant was found stable in all patients. The mean Harris score increased subsequently throughout the follow-up interval and differences were statistically significant (p < 0.0001). None of the patients had reactivation of tuberculosis infection postoperatively.

Conclusion

Total hip arthroplasty is a reliable option to treat active advanced tubercular hip arthritis and gives good functional outcome with proper preoperative and postoperative ATT regimen.

Protrusio acetabuli in tubercular hip: Outcome of femoral head as autologous bone graft used during total hip replacement

Purpose

Here we present a study of a tuberculosis hip protrusion with a large acetabular defect treated by total hip replacement using a novel technique without the use of any protrusio ring, wire mesh, or cage. To our knowledge, such a technique has not been described in the literature previously.

Methodology

25 patients with a past treatment history of hip tuberculosis came to our medical college with complaints of worsening pain in the hip joint and limping. The hip pain and limping were progressive in nature and became more severe, and his affected lower limb shortened.

Results

The average AK distance (horizontal distance between Kohlar line and the medial acetabular border) before surgery was 8 mm (range: 1-16). For the acetabular implant, the mean abduction angle was 45° (range: 41-48), and the mean anteversion angle was 18° (range: 13-24). The average preoperative shortening for limb length inequality was 4 mm (range: 0-11). The average HHS (Harris Hip Score) during follow-up was 87.6 points.

Conclusion

In TB hip protrusio, an autograft of the femur head is used to fill the acetabular defect and provide a good approach for these patients without any extra economic burden or complications as seen in a metallic ring or cage.

A Subacute Presentation of Isolated Tuberculous Septic Hip Arthritis

Tuberculous septic arthritis is a rare type of septic arthritis that is caused by Mycobacterium tuberculosis. However, it can lead to devastating complications if not diagnosed and treated correctly. We hereby report a 41-year-old female with no medical history who presented with a three-week history of right hip pain and inability to bear weight, found to have moderate to severe tenderness at the right anterior hip and gluteal area and limitation of joint movement. Magnetic resonance imaging (MRI) of the hip showed features of right hip septic arthritis with synovitis and anteromedial and posteromedial small collections. She was diagnosed with tuberculosis (TB) after joint fluid aspiration, and she was started on anti-TB treatment including isoniazid, rifampicin, ethambutol, and pyrazinamide directly after. Considering the case and the subacute presentation that can mimic bacterial septic arthritis, clinicians should always consider TB infection in their differential diagnosis upon assessing a suspected patient with septic arthritis even with a subacute presentation to achieve the correct diagnosis and start appropriate treatment to avoid its harmful complications.

Imaging recommendations and algorithms for pediatric tuberculosis: part 2-extrathoracic tuberculosis

Despite advances in diagnosis and treatment in recent years, tuberculosis (TB) remains a global health concern. Children are amongst the most vulnerable groups affected by this disease. Although TB primarily involves the lungs and mediastinal lymph nodes, it can affect virtually any organ system of the body. Along with clinical history combined with physical examination and laboratory tests, various medical imaging tools help establish the diagnosis. Medical imaging tests are also helpful for follow-up during therapy, to assess complications and exclude other underlying pathologies. This article aims to discuss the utility, strengths and limitations of medical imaging tools in the evaluation of suspected extrathoracic TB in the pediatric population. Imaging recommendations for the diagnosis will be presented along with practical and evidence-based imaging algorithms to serve as a guide for both radiologists and clinicians.

Total Hip Replacement in Active and Inactive Tuberculosis Hip: A Systematic Review

Introduction

Tuberculosis of the hip joint is a debilitating disease that can result in severe joint destruction, eventually leading to painful arthritis of the hip. Total hip arthroplasty (THA) in patients with advanced arthritis offers a painless and mobile joint with good functional outcome but some aspects of THA in TB hip have been controversial in the past due to the concerns of disease reactivation, especially when disease activity is factored in. Various factors like timing of surgery, Antitubercular therapy (ATT) initiation timing, reactivation, complications etc needs to be evaluated very carefully before planning for such cases.

Methods

Electronic databases like MEDLINE, EMBASE, Cochrane library, Clinicaltrials gov and OpenGrey were searched. The key words used were "Tuberculosis", "Tuberculosis of hip", Hip tuberculosis, "TB", "THR", "total hip replacement", "total hip arthroplasty","THA", "ankylosed hip", "fused hip", "arthrodesis" along with boolean operators "AND" and "OR". Out of a total of 1634 articles, 38 were selected for full text review and 22 articles were finally included in the study.

Results

For the timing of surgery most authors relied on the inflammatory markers to settle down with ATT before performing THA. 15 authors advocated use of pre-operative ATT with 6 studies recommending at least 2 weeks and 3 studies advocating atleast 3 months of ATT pre surgery.Single stage THA was performed in most studies(214 hips vs 18 hips) as opposed to 2 or 3 stage surgery. In the active disease 72.8% of the hips had uncemented prosthesis, 25.6% hips underwent cemented and 1.5% hips had hybrid THA fixation. Overall reactivation of the infection was seen in 2.47% cases. All authors reported excellent clinical improvement (mean HHS improvement 37.17 to 88.62).

Do Changes in Hemoglobin and C-Reactive Protein Levels in Patients With Hip Tuberculosis After Two Months of Treatment Predict Tubercle Bacilli Deletion?

Background and objective Tuberculosis (TB) of the hip refers to the hip infection caused by tubercle bacilli. Treatment for hip TB includes anti-TB medications, surgery to remove joint abscesses, and orthopedic surgery. It is necessary to conduct tests to confirm that the tubercle bacilli have been eradicated following the treatments. In this study, we aimed to assess the change in hemoglobin and C-reactive protein (CRP) serum levels in patients with hip TB before and two months after receiving specific treatments. We sought to determine whether they are significant tests for the treatment prognosis of hip TB. Methods We employed a prospective cohort design for this study. It was conducted at National Lung Hospital, Hanoi, and involved 24 hip TB patients with intra-articular abscesses who were treated at the center during the period from October 2016 to October 2021. Blood hemoglobin, CRP serum level, and abscesses on hip MRI were assessed before and two months after treatments. Hemoglobin was examined by spectrophotometry, and CRP serum was measured using the immunoturbidimetric method. Results Before treatments, the average hemoglobin level in the patients was 11.48 ± 1.85 g/dl; the average CRP serum level was 63.53 ± 36.47 mg/l. After two months of treatments, the average hemoglobin level increased significantly to 13.22 ± 1.36 g/dl, while the average CRP level reduced significantly to 12.55 ± 11.34 mg/l. However, five cases displayed abnormal findings. These five individuals continued to have intra-articular abscesses. Conclusion In individuals who reacted well to the therapy, blood hemoglobin and CRP serum levels improved. Blood hemoglobin and serum CRP assays can be utilized to monitor outcomes in hip TB therapy.

Clinical Outcomes of Delayed Osteoarticular Tuberculosis: A Review of 30 Cases

Purpose

The lack of knowledge regarding osteoarticular tuberculosis (TB) cases in Indonesia leads to delayed and chronic conditions. This study aims to evaluate clinical outcomes of patients with osteoarticular TB.

Materials and Methods

Thirty osteoarticular cases were retrospectively analyzed, with a focus on non-immunocompromised patients without spine involvement. Chemotherapy length, operative treatment method, and infection recurrence were evaluated.

Results

The majority (60%) of patients were aged between 19 to 49 years. The most common complaint was painful swelling, particularly during physical activity. Weight-bearing joints, such as the hips, knees, and ankles, were the most affected. Laboratory results showed over half of the patients had anemia, 96% had elevated erythrocyte sedimentation rate (ESR), and 76% had elevated C-reactive protein (CRP) levels. Radiological findings varied, with lytic lesions, abscesses, and joint destruction observed. All patients presented with pathognomonic histological tubercle appearances, with caseous necrosis, lymphocytes, and Langhans giant cells present. Twenty-nine cases were treated with anti-TB drugs for 12 months, while one recurrent case received the drugs for 24 months. All patients underwent surgery to gain local infection control.

Conclusion

Osteoarticular TB is a common manifestation of extrapulmonary TB and must not be overlooked. Early detection of osteoarticular TB may prevent limb morbidity. Although anti-TB drugs are the primary treatment for osteoarticular TB, in some cases, surgery is required to establish a diagnosis and gain local infection control.

Treatment of Stage I-III Hip Joint Tuberculosis With Open Surgical Debridement and Hip Spica in Children: A Retrospective Study

BACKGROUND

This study aimed to evaluate the outcome of surgical debridement combined with postoperative hip spica immobilization in the treatment of hip joint tuberculosis in children.

METHODS

This retrospective study enrolled 87 children with stage I to III hip joint tuberculosis treated surgically at our hospital from January 2010 to January 2016. All patients considering hip tuberculosis routinely received a 4-week conservative treatment first, including rest, protected weight-bearing, and 4-drugs antitubercular chemotherapy. Surgical debridement was indicated when there was no relief after this conservative protocol. Patients were divided into 2 groups according to the duration of hip spica immobilization after operation: group A (hip spica for 4 wk, 39 patients) and group B (hip spica for 6 wk, 48 patients). All patients were recommended partial weight-bearing for 7 days and then followed the same hip joint exercises program when spica was removed. Postoperative radiographs, hip dislocation or subluxation, and modified Harris hip score (MHHS) were assessed. All patients were followed up at least 5 years.

RESULTS

There were 87 patients enrolled in our study, including 34 females and 53 males, with a mean age of 7.2±2.8 years old (range: 2 to 14 y). No significant difference was observed between these 2 groups in baseline data. In group A, the mean MHHS improved from 52.1±14.7 before surgery to 87.8±8.3 at the final follow-up ( P <0.000). In group B, there was also a significant difference between the preoperative MHHS (52.7±9.4) and the final MHHS (88.6±6.5) ( P <0.000). Although there was no significant difference between these 2 groups in the final MHHS ( P =0.593), there were also no significant differences between these 2 groups in wound healing delay (3 in group A and 6 in group B, P =0.705) and pathologic subluxation (3 in group A and 1 in group B, P =0.467). The only difference between group A (79.2±8.5) and group B (75.5±7.5) was the early functional outcome assessed by using MHHS after 1 month of hip joint exercises ( P =0.032).

CONCLUSIONS

Surgical debridement combined with antitubercular chemotherapy is an effective treatment for stage I to III hip tuberculosis in children when there is no improvement after conservative treatment. Prolonged hip spica immobilization may not reduce the risk of hip subluxation after open surgical debridement but could lead to a delay in early functional recovery. Time of spica immobilization should be individualized and based on the surgeon's evaluation and the patient's condition.

Proximal femur shaft fracture in a case of ipsilateral resection arthroplasty of a tuberculous hip - A rare case report

Femur shaft fracture is a common entity in orthopaedic practice, but how commonly does one encounter a subtrochanteric femur fracture in ipsilateral resection arthroplasty of a tuberculous hip after a decade of uneventful unassisted ambulation post resection procedure ? Till date only 2 patients have been reported worldwide with femur diaphyseal fracture with a history of ipsilateral resection arthroplasty all performed within a year of fracture occurrence. The intriguing factor of our case was the fact that post resection, patient was ambulatory for a decade and the fracture occurred at a subtrochanteric level. Thus we report a case of 35 year old male with subtrochanteric femur fracture due to minor trauma to right thigh, with a history of tuberculous arthritis of right hip for which surgical management in the form of resection arthroplasty was done 10 years back. After a thoughtful decision making and plan formulation we managed the patient with surface fixation with a pre contoured GT (greater trochanter) configuration plate after taking into consideration status of intact GT, osteoporosis, pseudoarthrosis level and post operative ambulation and rehabilitation.

One-stage total hip arthroplasty for advanced hip tuberculosis combined with developmental dysplasia of the hip: A case report

BACKGROUND

A patient with advanced tuberculosis of the hip joint combined with Crowe type IV developmental dysplasia of the hip (DDH) and a drainage sinus is a rare condition. There are no previous reports of this condition, and it is a complex challenge for surgeons to develop a treatment scheme.

CASE SUMMARY

We report a 73-year-old male patient with severe hip pain and drainage sinus of the left hip for one month. Approximately 40 years ago, a drainage sinus occurred at the lateral left hip was healed at the local hospital with anti-infectious therapy. After the sinus healed, gradual pain occurred in the left hip for 40 years. Approximately one month prior, hip pain was sharply aggravated, and a drainage sinus reoccurred in the left hip. The X-ray and computed tomography examinations showed destruction of the head and neck of the left femur, as well as an acetabular deformity. The results of Mycobacterium tuberculosis antibody and Xpert were positive. Therefore, the patient was diagnosed with advanced TH combined with Crowe type IV DDH. After 22 d of treatment with anti-tuberculosis chemotherapy, the sinus healed, and the patient underwent one-stage total hip arthroplasty (THA) surgery consisting of debridement, osteotomy, and joint replacement. After surgery, the patient received anti-tuberculosis chemotherapy drugs for nine months, with no recurrent infection. After one year of follow-up, the Harris score of the patient increased from 21 pre-THA to 86.

CONCLUSION

Although drainage sinuses are a contraindication to one-stage THA, one-stage THA is still an effective and safe surgical method after the sinus heals.

Early clinical outcomes of one-stage total hip arthroplasty for the treatment of advanced hip tuberculosis

OBJECTIVE

To investigate the clinical efficacy of one-stage total hip arthroplasty (THA) for treating the advanced hip tuberculosis.

METHODS

A retrospective study was conducted from July 2013 to June 2018, including 19 patients with advanced hip tuberculosis. All patients underwent total hip arthroplasty through posterior approach, and the surgical efficacy was evaluated.

RESULTS

Nineteen patients were followed up from 24 months to 48 months, the mean follow-up were 32.1 months. All the incisions healed in grade A. There were no aseptic loosening, dislocation or recurrence of hip tuberculosis after operation. At the last follow-up, the Harris score of the patients was (89.3 ± 6.7), which was significantly higher than (38.2 ± 10.5) of the patients before operation (P < 0.05); the flexion-extension range of motion was (93.6° ± 12.1°), which was significantly larger than (38.2° ± 10.5°) of the patients before operation (P < 0.05).

CONCLUSION

The one-stage total hip arthroplasty with regular antituberculosis treatment can attain satisfactory clinical efficacy in the treatment of advanced hip tuberculosis, which can relieve the joint pain and improve the joint function, without recurrence of hip tuberculosis.

Tuberculous septic arthritis of the hip with large abscess formation mimicking soft tissue tumors: A case report

Background

Tuberculous septic arthritis is an infection that occurs inside the joint or synovial fluid and joint tissues caused by Mycobacterium tuberculosis. It may show wide variability of clinical symptoms and imaging appearance, ranging from asymptomatic with a normal radiographic examination to severe joint pain along with joint destruction, osteomyelitis, and abscess formation. This article presents radiographic and MR imaging appearance from a case of tuberculous septic arthritis with large abscess formation mimicking soft tissue tumor.

Case presentation

We reported a 32-year-old female with a slowly enlarging lump on her right proximal thigh within the last 4 months along with slowly progressing joint pain. Both radiographic and MR images showed destruction of the femoral head and acetabular roof, with a formation of large rim-enhanced abscess that extending superficially and distally until mid-thigh. The patient underwent open drainage surgery and excisional biopsy. Histopathological examination showed chronic granulomatous inflammation caused by tuberculous infection.

Conclusion

MR imaging combined with radiographic and clinical information played a very important role in the diagnosis of tuberculous septic arthritis with abscess, and to differentiate it from soft tissue neoplasms.

Total hip arthroplasty in tubercular arthritis of the hip - Surgical challenges and choice of implants

Osteoarticular tuberculosis of the hip joint can be a debilitating disease that can result in severe cartilage degeneration, destruction, and eventual painful arthritis of the hip. Usually, a secondary affliction to a primary lung disease, Tuberculosis (TB) of the hip can be difficult to diagnose due to its indolent natural history and deep-seated nature of the hip joint itself. Untreated, ultimately TB hip leads to disabling arthritis of the hip with limitation of activities of daily living, livelihood, and socio-economic consequences. Historic surgical options such as arthrodesis and excision arthroplasty of TB hip have limitations and several disadvantages. Total hip arthroplasty (THA) is a viable option to restore mobility and relieve pain in patients with severe post-tuberculous arthritis but has been controversial in the past due to the concerns of disease reactivation. We evaluate the current role of THA in TB of the hip, its various applications in different presenting scenarios with a guide to surgical tips and tricks for managing this challenging condition.

Tubercular arthritis presenting as osteonecrosis of the femoral head: A case report

A tuberculosis hip that presents as osteonecrosis of the femoral head is an extremely rare condition. There are no previous reports of this condition, and there is no consensus on the method of total hip arthroplasty for this group of patients. We present a case of a 72-year-old man who had clinical gradual hip pain in both hips for 1 year. He was diagnosed with post-collapsed osteonecrosis of the femoral head in both hips and was scheduled for total hip arthroplasty of the left hip. During his clinical follow-up, he suddenly experienced excruciating acute pain. Investigation to rule out infection was positive for only C-reactive proteins, but his synovial fluid work-up was negative. An intraoperative finding revealed that there was collapse of the femoral head with eroded acetabular cartilage and rice body–like synovitis. Total hip arthroplasty was performed, and the tissue was sent for diagnosis. Tissue acid-fast bacilli were positive, so the patient received anti-tuberculosis drugs for 9 months, with no recurrent infection. Tuberculosis arthritis presenting as osteonecrosis of the femoral head is a complex condition that is difficult to diagnose due to the radiographic pictures of femoral head collapse and arthritic change being similar in both diseases. Acute pain onset with rapid collapse of the femoral head should be a consideration or suspect for this infectious condition. Hence, investigation to rule out infection is important. Anti-tuberculosis drugs are the standard treatment for early or advanced arthritis, and one-stage or two-stage total hip arthroplasty is the choice of treatment for advanced arthritis.

The association between skeletal lesions and tuberculosis diagnosis using a probabilistic approach

Sensitivity and specificity estimates for 18 skeletal lesions were generated from modern skeletons for future paleoepidemiological analyses of tuberculosis prevalence in archaeological samples. A case-control study was conducted using 480 skeletons from 20^th century American skeletal collections. One-half of the skeletons were documented tuberculosis cases (Terry Collection). The remaining age and sex-matched skeletons were controls (Bass Collection). The association between 18 candidate skeletal lesions and tuberculosis was established by comparing lesion distributions in case and control groups. Lesion indicators at six locations - visceral surface of ribs, ventral vertebral bodies, lateral part of ilium, acetabular fossa, iliac auricular surface, and ulna olecranon process - occurred significantly more often among cases than in controls, and were associated with one another. The most useful indicator proved to be a bony reaction on ventral thoracic and lumbar vertebral bodies. Its presence means a 53.3% probability of a true tuberculosis diagnosis. Because of the nature of the reference sample - 20th century American cases - sensitivity and specificity estimates will better estimate disease prevalence in archaeological samples from cultural settings where pulmonary tuberculosis predominated. The general approach of this proof-of-concept study is applicable to other diseases that occur commonly and affect bone.

Pyogenic Arthritis

The incidence of septic arthritis among children in developed countries is estimated to be 4 to 10 cases per 100,000 children per year, peaking at about age 3 years. The most common causative organism is Staphylococcus aureus, although the microbiology varies by age. Prompt diagnosis and treatment is critical to prevent long-term sequelae. Empiric therapy should target the most likely causative organism(s) and total duration generally falls between 10 days and 4 weeks depending on clinical course, patient age, and organism. A short intravenous course is sufficient in most cases. Unusual and alternate causes of arthritis should be considered in special cases. [Pediatr Ann. 2019;48(9):e354-e359.].

Diagnosis and management of spinal tuberculosis combined with brucellosis: A case report and literature review

Tuberculosis combined with brucellosis is a very rare condition. Overlapping clinical presentation and laboratory parameters of tuberculosis and brucellosis may lead to misdiagnosis or delayed diagnosis of the condition. The current study presents the case of a 45-year-old male with symptoms of lower back pain, non-tender swelling in the right flank, intermittent hyperpyrexia, sweating, body aches and numbness and weakness of right lower limb. A lumbar computed tomograph (CT) scan and magnetic resonance imaging indicated vertebral destruction and the formation of sequestra and thecal sac compression. Tuberculosis was suspected, but subsequent culture of blood and pus revealed the co-infection of Mycobacterium tuberculosis and Brucella melitensis. The patient was treated with antibiotics, CT-guided percutaneous drainage of the abscess and posterior approach decompression, debridement, instrumentation and fusion. Co-existence of spinal tuberculosis and brucellosis is rare and clinicians should strengthen the awareness of such conditions in similar patients. CT-guided percutaneous drainage is effective in the diagnosis and management of spinal tuberculosis with abscess.

Bacille Calmette-Guérin Vaccine-Induced Tuberculous Hip Osteomyelitis in an Infant: Case report

To this day, tuberculosis (TB) continues to pose a significant global health burden. The World Health Organization's Expanded Programme on Immunization (EPI) recommends the bacille Calmette-Guérin (BCG) vaccine for infants to protect against the haematogenous spread of primary TB and other more severe types of TB infection. We report an eight-month-old boy who presented to the Armed Forces Hospital, Muscat, Oman, in 2015 with a one-month history of intermittent fever associated with a limited range of motion in the right hip area. He was up-to-date with his EPI vaccinations and had no history of exposure to individuals with TB infections. He was initially treated for bacterial septic arthritis; however, a GeneXpert TB assay revealed the presence of Mycobacterium tuberculosis, BCG strain. To the best of the authors' knowledge, this is the first documented case from Oman of a child with TB hip osteomyelitis due to a BCG vaccination.

Diagnosis and treatment of paediatric tuberculosis: An insight review

Tuberculosis (TB) is a major public health problem, invading all age groups world-wide. It is an opportunistic infection affecting the individuals alone or with co-infections. Childhood TB is a neglected aspect and a significant health problem in epidemic areas. It constitutes more than 20% of TB incidence. Pediatric TB exists in the shadow of adult TB. The clinicians concentrate on pulmonary manifestation of TB, whereas it is a major problem in both pulmonary and extra-pulmonary infections. The rate of infection with this disease is mostly associated with poverty, social disruption and human immunodeficiency virus (HIV) infection. The diagnosis of extra-pulmonary TB (EPTB) is more difficult than pulmonary TB (PTB). Delayed diagnosis and executive treatment contribute to increase in the mortality rate in endemic areas. This article provides the evidence-based simple and safe screening method, indicating rapid, highly sensitive and specific diagnostic tests for pulmonary and EPTB in children. The most important aspect of treatment is the correct course of anti-tubercular drugs. This review serves the purpose of quick reference for microbiologists, epidemiologists, academicians, students and researchers. It provides guidance regarding early diagnosis and treatment accuracy of pediatric TB.
