Primary tuberculosis of the tongue: a case report

AIM: The purpose of this article is to report a rare case of primary tuberculosis of the tongue. BACKGROUND: Tuberculosis is an infectious, chronic granulomatous disease that can involve almost any organ in the body, but primary lesions are usually confined to the lungs. Oral lesions are an infrequent occurrence in tuberculosis, and tuberculosis of the oral cavity is often a consequence of active pulmonary tuberculosis. Although primary tuberculosis in the oral cavity has been documented, it is a rare occurrence. REPORT: A 42-year-old male patient presented with chief complaints of severe pain and ulceration on the ventrolateral surface of the left side of the tongue, measuring about 1.25 x 1.50 cm with surrounding erythema and induration of one-month duration. The ulcer was initially painless but became painful later with increased severity over time. The sore tongue caused difficulty in eating, drinking, swallowing, and even talking. The patient also complained of malaise for some duration, but there was no history of fever, cough, weight loss, and his bladder-bowel habits were normal. An excisional biopsy differentiated the lesion from squamous cell carcinoma and confirmed the diagnosis. SUMMARY: Even though primary tuberculosis in the oral cavity is a rare finding, it must be included in the differential diagnosis of mucosal lesions. This case provides a clinical example of the importance of this inclusion for the well being of the patient and for the community due to the communicable nature of the disease.     

Prevalence of facet joint pain in chronic low back pain in postsurgical patients by controlled comparative local anesthetic blocks

OBJECTIVE: To evaluate the prevalence of facet joint pain in patients with chronic low back pain (CLBP) after surgical intervention(s). DESIGN: A prospective, nonrandomized, consecutive study. SETTING: An ambulatory interventional pain management setting. PARTICIPANTS: The prevalence of facet joint pain was evaluated in patients with CLBP after various surgical intervention(s) referred to an interventional pain management practice. The sample was derived from 282 patients with persistent CLBP after various surgical intervention(s). Of these, 242 patients consented to undergo interventional techniques. A total of 117 consecutive patients with chronic, nonspecific low back pain, after lumbar surgical intervention(s) were evaluated with controlled, comparative local anesthetic blocks. INTERVENTIONS: Controlled, comparative local anesthetic blocks (1% lidocaine or 1% lidocaine followed by .25% bupivacaine) under fluoroscopic visualization using 0.5mL to block each facet joint nerve. MAIN OUTCOME MEASURES: A positive response was defined as at least 80% reduction of pain with ability to perform previously painful movements. A positive response was considered to be pain relief from the lidocaine block lasting at least 1 hour or at least 2 hours or greater than duration of relief with lidocaine when bupivacaine was used. Controlled, comparative local anesthetic blocks were used to eliminate false-positive results. Valid information is only obtained by performing controlled blocks in the form of comparative local anesthetic blocks, in which, on 2 separate occasions, the same joint is anesthetized by using local anesthetics with different durations of action. If patients obtained appropriate response with both blocks, they were considered a positive. If they obtained appropriate response with lidocaine but not with bupivacaine, they were considered false-positive, whereas if the response was negative with lidocaine, they were considered negative. RESULTS: The prevalence of lumbar facet joint pain in patients with recurrent pain after various surgical intervention(s) was 16% (95% confidence interval, 9%-23%). The false-positive rate with a single block with lidocaine was 49%. CONCLUSIONS: Facet joints are clinically important pain generators in a small but significant proportion of patients with recurrent CLBP after various surgical intervention(s).

Relationship between diabetic retinopathy microalbuminuria and other modifiable risk factors

BackgroundDiabetic Retinopathy (DR) is an important microvascular complication of diabetes that can lead to irreversible blindness. Microalbuminuria is strongly associated with diabetic retinopathy and can be used as a reliable marker of diabetic retinopathy.AimTo assess the association between DR, microalbuminuria, and other modifiable risk factors in patients with type 2 diabetes.Methodology3090 patients with T2DM visiting North Delhi Diabetes Centre, New Delhi between July 2016 to October 2019 were evaluated for the clinical and biochemical parameters that included urinary albumin, HbA1C, lipid profiles, serum creatinine estimation and underwent biothesiometry.Results3090 patients (1350 females and 1740 males), with mean age of 52.7 ± 9.2 years and diabetes duration ranging from 1 to 19 years (mean 9.4 ± 6), duration of less than 5 years, 6–10 years and more than 10 years in 52%, 26% and in 22%, respectively. Duration of diabetes was strong predictor of retinopathy (p = 0.001). The HbA1c and BMI in patients with DR was significantly higher than in those without DR. 18.2% patients were diagnosed to have retinopathy. Peripheral neuropathy was observed in 24.2% and was positively associated with DR (p = 0.002). 33.9% and 4.5% patients had microalbuminuria macroalbuminuria, respectively and 9.7% patients had creatinine >1.3 mg/dL. There was significant positive relationship between different grades of retinopathy and albuminuria.ConclusionsOur study is a large real-world study that demonstrates that HbA1c, BMI, duration of diabetes, microalbuminuria and peripheral neuropathy are relatively, yet cohesively contributing factors towards varying grade of retinopathy.     

Malaria infections are randomly distributed in diverse holoendemic areas of Papua New Guinea

Malaria is holoendemic in the lowlands of Papua New Guinea (PNG), and interactions among Plasmodium species may influence prevalence of mixed infections. Previously, field samples from a cross-sectional survey in Dreikikir, East Sepik Province, analyzed by blood smear and polymerase chain reaction (PCR), showed that mixed infections were common and randomly distributed in this malaria endemic region. To evaluate further whether Plasmodium species distribution is random, blood smear- and PCR/sequence-specific oligonucleotide probe hybridization-based analyses of cross-sectional survey samples were conducted in 2 additional malaria holoendemic regions of northern PNG. Despite ecologic, species prevalence, and transmission season differences in these new surveys, all 4 Plasmodium species were found to be randomly distributed in each area; random distribution patterns also were observed when study populations were divided into age groups. These findings provide consistent evidence that Plasmodium species infections occur independently of one another in PNG malaria holoendemic sites. This independent occurrence suggests that age-dependent, acquired malaria immunity has limited influence on the distribution pattern of Plasmodium species infections in endemic human populations; infection by 1 human malaria parasite species does not reduce susceptibility to infection by others; and malaria vaccines would exhibit limited protection against blood-stage infection by heterologous Plasmodium species.     

Risk Stratification for the In-Hospital Mortality in Subarachnoid Hemorrhage: The HAIR Score

Background

The intracerebral hemorrhage (ICH) score is a simple grading scale that can be used to stratify risk of 30 day mortality in ICH patients. A similar risk stratification scale for subarachnoid hemorrhage (SAH) is lacking. We sought to develop a risk stratification mortality score for SAH.

Methods

With approval from the Institutional Review Board, we retrospectively reviewed 400 consecutive SAH patients admitted to our institution from August 1, 2006 to March 1, 2011. The SAH score was developed from a multivariable logistic regression model which was validated with bootstrap method. A separate cohort of 302 SAH patients was used for evaluation of the score.

Results

Among 400 patients with SAH, the mean age was 56.9 ± 13.9 years (range, 21.5–96.2). Among the 366 patients with known causes of SAH, 292 (79.8 %) of patients had aneurysmal SAH, 65 (17.8 %) were angiogram negative, and 9 (2 %) were other vascular causes. The overall in-hospital mortality rate was 20 %. In multivariable analysis, the variables independently associated with the in-hospital mortality were Hunt and Hess score (HH) (p < 0.0001), age (p < 0.0001), intraventricular hemorrhage (IVH) (p = 0.049), and re-bleed (p = 0.01). The SAH score (0–8) was made by adding the following points: HH (HH1-3 = 0, HH4 = 1, HH5 = 4), age (<60 = 0, 60–80 = 1, ≥80 = 2), IVH (no = 0, yes = 1), and re-bleed within 24 h (no = 0, yes = 1). Using our model, the in-hospital mortality rates for patients with score of 0, 1, 2, 3, 4, 5, 6, and 7 were 0.9, 4.5, 9.1, 34.5, 52.9, 60, 82.1, and 83.3 % respectively. Validation analysis indicates good predictive performance of this model.

Conclusion

The SAH score allows a practical method of risk stratification of the in-hospital mortality. The in-hospital mortality increases with increasing SAH mortality score. Further investigation is warranted to validate these findings.
