Rare case of tubercular parotid abscess.

Acute parotitis progressing to parotid abscess is rare in children. Staphylococcus aureus is the usual pathogen in parotid abscess. Granulomatous parotid abscess due to tubercular aetiology is extremely rare. Authors report a case of chronic parotid abscess in a child who received multiple courses of antibiotics without any cure. The ultrasonography and CT scan of the parotid gland confirmed the extent of parotid abscess and the changes in the parotid lymph nodes. The surgical drainage and the biopsy of the lymph nodes lead to the diagnosis of granulomatous abscess. The antitubercular therapy finally cured the disease without further recurrence.

Respuesta paradojal al tratamiento antituberculoso en una paciente con SIDA / PARODOXICAL RESPONSE TO ANTITUBERCULOSE TREATMENT IN A PATIENT WITH AIDS

La tuberculosis (TB) es una enfermedad infectocontagiosa de gran importancia en la salud pública y representa una de las 10 principales causas de muerte a nivel mundial. Una de las complicaciones del tratamiento antituberculoso es la respuesta paradojal, que se define como un empeoramiento clínico o la aparición de nuevas lesiones en un paciente que comienza un tratamiento antifímico. Esta reacción está mediada por una respuesta de hipersensibilidad a los antígenos de Mycobacterium tuberculosis. Suele aparecer entre 2 y 4 meses luego de iniciado el tratamiento antituberculoso, generalmente precedida por una mejoría inicial del cuadro. Se presenta una mujer con sida y tuberculosis ganglionar con respuesta paradojal a la terapéutica antimicobacteriana y se realiza una revisión bibliográfica del tema.

Tuberculosis (TB) is an infectious disease of great importance in public health and represent one of the 10 leading causes of death worldwide. One of the complication of the antituberculous treatment is the paradoxical reaction, which is defined as a worsening or the appearance of new lesions in a patient receiving antimicobacterial treatment. This paradoxical response is mediated by a hypersensitivity reaction to mycobacterial antigens. It usually appears between 2 and 4 months after initiation of tuberculosis treatment and is preceded by an initial improvement of the clinical condition. Here, we describe a woman with AIDS and lymph node tuberculosis with a paradoxical reaction to antimycobacterial therapy and the subject is reviewed.

A 21-Year-Old Immune-Competent Man With Recurrent Cough.

CASE PRESENTATION: A 21-year-old Chinese man presented with a nonproductive cough for the past 5 months. He denied fevers, chills, night sweats, chest pain, dyspnea, hemoptysis, or weight loss. He was an undergraduate with an unremarkable medical history. He denied any sick contacts and he never smoked. Laboratory tests showed a leukocyte count of 11,200/µL (normal range, 3,500-9,500/µL) with a high neutrophil count and a raised erythrocyte sedimentation rate of 81 mm/h. The purified protein derivative skin test result was positive, and a TB test (T.SPOT.TB; Oxford Immunotec) produced a positive result. The HIV test result was negative. The lung window of the patient's thoracic CT scan showed mottled, patchy opacification in the right lower lobe, and enlarged mediastinal and right hilar lymph nodes (Fig 1A). Bronchoscopy showed mucosal swelling and congestion (Fig 1B). A lymph node (station 11R) biopsy, obtained by endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) (Fig 1C), showed nonspecific necrosis. An acid-fast bacillus smear of bronchial secretion produced negative results. He was administered empiric anti-TB therapy (ethambutol, isoniazid, pyrazinamide, and rifapentine). But his cough had not improved by 4 months later. Thus he came to our hospital for a second opinion.

Pancreatic tuberculosis: A systematic review of symptoms, diagnosis and treatment.

INTRODUCTION: Although pancreatic tuberculosis (TB) is traditionally considered to be a rare clinical entity, in recent times, an increase in the number of reports of pancreatic TB has been noted. We conducted a systematic review in order to summarise currently available data on pancreatic TB. METHODS: A comprehensive literature search of Medline, Scopus and ISI Web of Science databases was conducted in order to identify papers reporting cases of pancreatic TB. The eligibility criteria for inclusion in the review required that the studies reported patient(s) affected by pancreatic TB and that individual data on age, sex, clinical presentation and outcome were available. RESULTS: In total, 116 studies reporting data on 166 patients were included in the analysis. The majority of patients were males (62.1%) diagnosed at a mean age of 41.61 ± 13.95 years. Most cases were diagnosed in Asia (50.0%), followed by North America (22.9%), Europe (20.5%), Africa (4.2%) and South America (2.4%). Human immunodeficiency virus (HIV) infection was diagnosed in 25.3% of those affected. Pancreatic TB most frequently presented itself in the form of a pancreatic mass (79.5%) localised mainly in the head (59.0%) and less frequently in the body (18.2%) and tail (13.4%). Extrapancreatic TB involvement most frequently affected the peripancreatic lymph nodes (47.3%). More than half of patients (55.2%) were subjected to laparotomy, while 21.08% underwent endoscopic ultrasound fine-needle aspiration biopsy. The presence of TB was identified most frequently through histological analysis (59.6%), followed by culture (28.9%), staining (27.7%) and, in a smaller number, by polymerase chain reaction (9.6%) and cytology (6.6%). Almost all patients received anti-tubercular pharmacological therapy (98.2%), while 24.1% underwent surgery. Despite treatment, 8.7% of patients died. CONCLUSION: Increased awareness of pancreatic TB is needed, not only in endemic areas but especially in relation to HIV infection and other clinical conditions associated with immunoincompetence.

Comparing tuberculosis in children aged under 5 versus 5 to 14 years old in a rural hospital in southern Ethiopia: an 18-year retrospective cross-sectional study.

BACKGROUND: There are few data available about childhood tuberculosis (TB) in rural hospitals in low-income countries. We assessed differences in epidemiological characteristics and treatment outcomes in children with TB aged 0-4 versus 5-14 years in rural Ethiopia. METHODS: For this retrospective cross-sectional study, we analyzed childhood TB registers from a rural Ethiopian hospital. We collected data on the number of cases, type of TB, and treatment outcomes using standard definitions. By means of binary and logistic regression analyses, data were compared from 1998 to 2015 in children aged under 5 versus those aged 5-14 years. RESULTS: We included 1282 TB patients: 583 (45.5%) were under 5 years old, and 699 (54.5%) were aged 5-14 years. More than half (67.2%, n = 862) had pulmonary TB (PTB), which was more common in younger children (82.5%, 481/583) than in older ones (54.5%, 381/699; p < 0.001). Most cases of PTB (87.5%, 754/862) were smear negative, including virtually all (99.6%, 479/481) younger children and most older ones (72.2%, n = 275/381; p < 0.001). The most common types of extrapulmonary TB (EPTB) were TB adenitis (54.5%, 229/420) and bone TB (20%, 84/420). Children under five showed a lower prevalence of adenitis TB (9.9% [58/583] versus 24.5% [171/699], p < 0.001), bone TB (2.9% [17/583] versus 9.6% [69/699], p < 0.001), and abdominal TB (0.9% [5/583] versus 6.3% [44/699], p < 0.001). Most diagnoses were new cases of TB (98.2%, 1259/1282). Overall, 63.5% (n = 814) of the children successfully completed treatment (< 5 years: 56.6%, 330/583; 5-14 years: 69.2%, 489/699; p < 0.001). In total, 16.3% (n = 209) transferred to another center (< 5 years: 19.4%, 113/583; 5-14 years: 13.7%, 96/699; p = 0.006). Thirteen percent of patients (n = 167) were lost to follow-up (< 5 years: 16.0%, 93/583; 5-14 years: 10.4%, 74/699; p = 0.004). Fifty-two (4.1%) children died (no age differences). Being aged 5-14 years was independently associated with successful treatment outcomes (adjusted odds ratio 1.59; 95% confidence interval: 1.16, 1.94, p = 0.002). CONCLUSIONS: We observed a very low diagnostic yield for spontaneous sputum smear in children with TB. In this rural setting in Ethiopia, very young children tend to present with new cases of smear-negative PTB. They have less EPTB than older children but more TB meningitis and show lower rates of treatment success.

Delays in the Diagnosis and Treatment of Tuberculous Lymphadenitis in Low-Incidence Countries: A Systematic Review.

Early detection and treatment of tuberculosis (TB) is essential to achieve the goals appointed in the WHO End TB Strategy. Tuberculous lymphadenitis (TBLA) is the most common manifestation of extrapulmonary TB, but the diagnosis can be challenging in low-incidence countries due to sparse and inconsistent clinical features, resulting in delay. We aimed to summarize and discuss the current literature on patient delay, health care delay, and total delay (i.e., time to first health care contact, diagnosis, and treatment) in patients with TBLA in TB low-incidence countries. A systematic review using PubMed was conducted, searching for studies set in TB low-incidence countries (defined as <20 per 100,000 citizens) that reported on health care seeking behaviour, patient delay, health care delay, and/or total delay. Studies were categorized by type of delay and compared. We identified 11 heterogeneous studies with highly variable observations. Mean patient delay varied from 55 to 154 days (range, 14-1,461), mean health care delay from 44 to 94 days (range, 7-224) and median total delay from 77.5 to 122 days (range, 0-2,820). Evidently, more comprehensive insights into the diagnostic pathway and delay in TBLA patients are warranted.

Diagnosis and Management of Children With Mycobacterium abscessus Infections in the Head and Neck.

PURPOSE: Controversy exists regarding the most appropriate treatment strategy for children with nontuberculous mycobacterial (NTM) cervical lymphadenitis. Mycobacterium abscessus (MAB) is an uncommon cause of NTM cervical lymphadenitis. The purpose of the present study was to evaluate diagnosis, management, and treatment outcomes in children with MAB-associated cervical lymphadenitis resulting from a pulpotomy. MATERIALS AND METHODS: This was a retrospective chart review of children with NTM lymphadenitis of the head and neck caused by MAB treated at Children's Healthcare of Atlanta hospitals (Atlanta, GA). The predictor variables were patient demographics, dental history, clinical presentation, imaging characteristics, laboratory findings, histopathologic examination, treatment, and complications. The outcome variable was disease resolution or persistence. RESULTS: Twenty-two patients (mean age, 6.5 yr) met the inclusion criteria. All patients had pulpotomy at 1 dental practice. The mean time from dental procedure to symptom onset was 43.1 days (range, 3 to 180 days). Children presented with cervical or submandibular swelling, facial swelling, gingival erythema, and skin erythema. Radiographic findings were submandibular or cervical lymphadenitis, maxillary or mandibular osteolysis, subcutaneous abscess, and pulmonary nodules. All children had confirmed or probable MAB infection diagnosed on the pathologic specimen. There were 2 distinct patient presentations that guided surgical management: isolated noninflammatory cervical lymphadenitis, which was partly or completely excised (n = 11), and adjacent extension or disseminated infection requiring subtotal lymph node excision, bone debridement, and postoperative antibiotics (n = 11). Most children required multiple surgical interventions to remove infected tissues. All achieved clinical resolution. CONCLUSION: In this cohort, treatment of NTM lymphadenitis caused by MAB depended on extent of disease and virulence of bacteria. When complete surgical excision was possible, disease resolution was achieved. However, in cases with adjacent extension or dissemination infection, postoperative antibiotics were necessary.

Conservative treatment for cutaneous fistula resulted from abscess formation in patients with tuberculous cervical lymphadenitis.

OBJECTIVE: This study describes the clinical characteristics and course of conservative treatment using anti-Tb medication and dressing in patients with tuberculous cervical fistula resulting from abscess formation, and to investigate factors prognostic of dressing and treatment duration. METHODS: The medical records of patients with tuberculous cervical lymphadenitis were reviewed, and 38 of these patients who presented with cutaneous fistula that resulted from abscess formation were included in the study. RESULTS: The mean duration of dressing until fistula closure was 3.7±2.0months (range 0.2-8.5), and the mean duration of treatment with anti-Tb medication was 10.6±2.6months (range 6.0-16.0). Patients with concomitant Tb, beyond the cervical lymph nodes showed significantly prolonged duration of dressing (4.6 months vs. 3.2 months, p=0.025) and anti-Tb medication (11.8 months vs. 9.8 months, p=0.015). CONCLUSION: Our results indicate that about 3.7 months of dressing was required for fistula closure. Tuberculous cervical lymphadenitis patients with fistula who had Tb beyond the cervical lymph nodes could be expected to require dressing for 4.6 months and prolonged and anti-Tb medication treatment.

Peripancreatic Tuberculous Lymphadenitis Diagnosed via Endoscopic Ultrasound-guided Fine-needle Aspiration and Polymerase Chain Reaction.

We performed endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) on a patient presenting with an asymptomatic peripancreatic mass-like lesion. The aspiration cytologic finding was class II. On positron emission tomography-computed tomography (PET-CT), there were hot spots in the left supra-clavicular lymph node and the peripancreatic lesion. A whole biopsy of the left supra-clavicular lymph node revealed tuberculous lymphadenitis. Polymerase chain reaction (PCR) using tissue obtained via EUS-FNA showed that the peripancreatic mass-like lesion was also positive for tuberculosis. We made a diagnosis of peripancreatic tuberculous lymphadenitis. In patients with enlarged lymph nodes, including those in the abdominal area, tuberculous lymphadenitis is a potential diagnosis.

Tuberculosis After Renal Transplant.

Tuberculosis is one of the leading infections after renal transplant, particularly in developing countries where the incidence and prevalence in the general population are high. Diagnosis requires bacteriologic and histologic confirmation. Interactions among the antitubercular drugs and the immunosuppressive agents have to be considered while prescribing, and surveillance for adverse effects is required. Although rare, case reports are available on extrapulmonary tuberculosis in allograft recipients. Here, we present a 25-year-old kidney transplant recipient who was diagnosed with lymph node tuberculosis under uncommon circumstances but who had a good outcome. This case report illustrates the difficulties in diagnosis of tuberculosis, changes in therapeutic protocols, and prognostic factors and highlights the effects of infectious complications with immunosuppressive therapy in this particular patient population.

Immune thrombocytopenia secondary to tuberculosis: a case and review of literature.

Immune thrombocytopenia (ITP) is an auto-immune condition that results in isolated thrombocytopenia associated with possibly lethal haemorrhage. In its secondary form, ITP can be triggered by many infectious and non-infectious conditions. Secondary ITP associated with tuberculosis (TB) has rarely been described in the literature. We report on a 22-year-old patient presenting with hypermenorrhoea and petechiae due to ITP secondary to tuberculous lymphadenitis. Normalisation of thrombocytopenia was only achieved after initiation of anti-tuberculosis treatment following failure of thrombocyte substitution and immune-modulatory treatment. A search of the literature available on TB-associated ITP identified 50 cases published between 1964 and 2016. We reviewed all cases using suggested case definitions on the likelihood of association between ITP and TB. A broad spectrum of TB sites was reported to be associated with ITP, and anti-tuberculosis treatment was the most effective therapy for platelet count normalisation. Time from initiation of anti-tuberculosis treatment to platelet count recovery ranged from 2 days to 3 months. In endemic regions, TB should be considered as an underlying cause of ITP. Early diagnosis of TB and initiation of anti-tuberculosis treatment appears crucial for rapid platelet count recovery, and can reduce the risks associated with long-term immunosuppression, transfusions and the time at risk for haemorrhage.

Suppurative Cervical Tuberculous Lymphadenitis Mimicking a Metastatic Neck Mass.

Tuberculosis is an important public's health problem in developing countries. Although tuberculosis is commonly found in lungs, it could also be found in lymph nodes, mouth, tonsils, tounge, nose, epiglottis, larynx, and pharynx of head-neck region. The most common form of extrapulmonary tuberculosis placed outside the lungs is tuberculous lymphadenitis. Tuberculosis lymphadenitis is the most commonly seen form of the extrapulmoner tuberculosis and usually invades the lymph nodules of the cervical region. An adult patient with tuberculous lymphadenitis has been presented within the context of the literature reviewed. A 42-year-old woman, who has admitted to our clinic with a fistulized mass in the right side of her neck, has been diagnosed and treatment has been performed. No other problems were found in the systemic examination of the patient. Since there is no specific finding of pulmonary tuberculosis, detailed investigations are required in patients admitted with the sypmtomps of neck mass.

[History of scrofula: from humoral dyscrasia to consumption]. / Historia de la escrófula: de la discrasia humoral a la consunción.

The term “scrofula” was used for a long time to designate a chronic swelling of cervical lymph nodes. This paper outlines the prevalent ideas on the nature, pathogenesis and the treatment of this disorder, from classical Greek medicine up to the 18th century. A Hippocratic treatise regarded scrofula as produced by an accumulation of phlegm, with a consequent imbalance or dyscrasia of the body humors. It was believed that it could heal spontaneously; but it could also soften, open through the skin and have an obstinate course. The treatment consisted mainly on local applications, incision to evacuate the soft content, or extirpation of the abnormal mass. In France and England, crowds of scrofulous patients were touched by the kings who were supposed to have a hereditary miraculous power to cure the disease. A Medieval text mentioned that scrofula could also affect other parts of the body. In the 17th century, scrofula was reputed as a frequent condition and was attributed to blood acrimony which coagulated in spongy organs. It was associated to phthisis or consumption due to the lethal outcome in some patients and to a cheese-like appearance of the pulmonary and the scrofulous lesions.

A clinical review of 38 cases of cervical tuberculous lymphadenitis in Japan - The role of neck dissection.

OBJECTIVES: After tuberculous pleurisy, lymphadenitis arising from cervical lesion is the second most common form of extrapulmonary tuberculosis. It is generally treated with antituberculosis agents, but some patients resist chemotherapy. In such cases, surgical resection is often considered as an alternative treatment. This study aims to evaluate the therapeutic outcome of cervical tuberculous lymphadenitis and the future course of treatment of this disease. METHODS: We retrospectively reviewed the clinical charts of patients diagnosed at the Tokyo Metropolitan Tama Medical Center between 2009 and 2015 and identified 38 cases of cervical tuberculous lymphadenitis. Precisely 798 patients were registered for primary tuberculosis at our institution during the same period. RESULTS: Patient ages ranged from 21 to 85 years (average: 58.9 years), and the male-to-female ratio was 1:1.2. The range of tuberculosis progression was as follows: 30 (78.9%) in only the cervical lymph node, 3 in the other (axillary, mediastinal, and abdominal) lymph nodes, 1 in the lung and vertebrae lumbales, 2 in the lung, and 1 in the pleural membrane. All 38 patients were initially treated with antituberculous drugs at the Department of Pulmonary Medicine based on guidelines for tuberculosis cases in Japan. In seven cases, the antituberculous drugs were replaced due to side effects. Four cases involved a single drug-resistant strain, and one case involved a double drug-resistant strain. Thirty-three (86.8%) cases were cured by chemotherapy alone. The three patients resistant to chemotherapy were successfully treated through neck dissection. Thirty-six cases (94.7%) were cured by chemotherapy or chemotherapy and surgery. CONCLUSION: Local therapy could prove effective in cervical tuberculous lymphadenitis patients who exhibit an inadequate response to drugs. The role of neck dissection in cervical tuberculous lymphadenitis remains an important consideration.

Tuberculosis lymphadenitis in a southeastern region in Tunisia: Epidemiology, clinical features, diagnosis and treatment.

AIM: To evaluate patients' profiles, demographics, clinical and therapeutic approaches and strategies in patients with tuberculous lymphadenitis (TBG). PATIENTS AND METHODS: A retrospective study of all TBG-confirmed cases admitted in a tuberculosis-specific health care facility between 1 January 2009 and 16 June 2013. RESULTS: A total of 181 clinical files were examined. Mean age was 32years old; the female/male ratio was 1.78 to 1. Raw milk consumption was noted in 1/3 of patients. Most cases involved the head and neck region (83.4%), nodes involvement, including axillary (12 cases), and mediastinal (9 cases). Clinical symptoms were present in only 55.2%. Tuberculin skin test (TST) was conducted with 82.6% positive responses. Diagnostics confirmation was done with anatomical pathology in most of the patients; only 56 of them had any microbiology analysis done. Demonstration of acid-fast bacilli in microscopy from either fine-needle aspirates or biopsies was done in 17.5% of cases, and cultures yielded positive results in 27%. Treatment duration was varied. Paradoxical reactions were noted in 12% and persistent lymphadenopathy after treatment completion was noted in 10% of cases. CONCLUSIONS: TBG remains a disease of interest. Today, its diagnosis and management is still a problem despite its increasing worldwide incidence, and especially in this study area. Disease control should be strengthened in this country.
