Pages 117 - 123

View PDF
Abstract
Background: Dengue fever is the most rapidly spreading mosquito-borne viral infection worldwide, and its clinical course is closely mirrored by characteristic alterations in the complete blood count. Hematological parameters are inexpensive, widely available, and useful for early diagnosis, severity stratification, and monitoring of dengue infection. Objective: To evaluate haemoglobin, total leukocyte count, differential leukocyte count, platelet count, haematocrit, and other haematological indices in patients with serologically confirmed dengue fever, and to correlate these parameters with disease severity according to the World Health Organization (WHO) 2009 classification. Methods: This hospital-based, cross-sectional observational study was conducted in the Department of Pathology in collaboration with the Department of General Medicine over a twelve-month period. Two hundred and twenty patients with NS1 antigen- and/or IgM-positive dengue fever were enrolled. Complete blood counts were performed on an automated haematology analyser at admission and correlated with clinical severity, classified as dengue without warning signs (DWoWS), dengue with warning signs (DWWS), and severe dengue (SD). Statistical comparisons were made using the chi-square test and one-way ANOVA, with p<0.05 considered significant. Results: Of 220 patients (mean age 32.6 ± 13.8 years; 58.6% male), 128 (58.2%) had DWoWS, 71 (32.3%) had DWWS, and 21 (9.5%) had SD. Thrombocytopenia (platelet count <150 × 10⁹/L) was present in 184 patients (83.6%) overall and in 100% of severe dengue cases, with mean platelet count falling progressively across severity groups (167.4 ± 42.6 vs 88.3 ± 31.5 vs 38.6 ± 18.2 × 10⁹/L; p<0.001). Leukopenia (<4.0 × 10⁹/L) was observed in 121 patients (55.0%) and was significantly more frequent in severe dengue. Mean haematocrit rose significantly with severity (38.4 ± 4.1% vs 42.7 ± 5.3% vs 47.9 ± 6.0%; p<0.001), and a haematocrit rise ≥20% above baseline was recorded in 76.2% of severe dengue patients. Atypical lymphocytosis and a reversed neutrophil-to-lymphocyte ratio were significantly associated with the later febrile phase and with severe disease. Conclusion: Progressive thrombocytopenia, leukopenia, and haemoconcentration, particularly when occurring together, are strongly associated with dengue severity and provide a simple, low-cost, and widely accessible means of risk-stratifying patients with dengue fever. Routine and serial monitoring of these parameters should be incorporated into clinical decision-making, especially in resource-limited settings.

Assessment of Visual and Auditory Reaction Times in Different Age Groups
Pages 111 - 116

View PDF
Abstract
Background: Reaction time (RT) is a simple, non-invasive, and sensitive index of sensorimotor and cognitive processing speed. Both visual and auditory reaction times are known to vary across the human lifespan, reflecting the combined influence of neural maturation in childhood and progressive sensorimotor decline in later adulthood. Objective: To assess and compare simple and choice visual reaction time (VRT) and auditory reaction time (ART) across four age groups spanning childhood to late adulthood, and to evaluate the relationship between age and reaction time. Methods: This cross-sectional observational study included 120 healthy volunteers divided equally into four age groups: 8–15 years (Group A), 16–30 years (Group B), 31–50 years (Group C), and 51–70 years (Group D). Simple and choice VRT and ART were measured using a computerized reaction time apparatus, with each subject undergoing multiple trials per stimulus type. Data were analyzed using one-way ANOVA, Pearson correlation, and linear regression to examine the relationship between age and reaction time. Results: Reaction time followed a U-shaped pattern across the lifespan, with the fastest responses recorded in the 16–30 year group and progressively slower responses in both the youngest (8–15 years) and oldest (51–70 years) groups. Across all age groups, ART was consistently and significantly faster than VRT (p < 0.001). Choice reaction times were significantly longer than simple reaction times in every group. Age showed a strong positive correlation with all reaction time measures (r = 0.69–0.78, p < 0.001), with choice visual RT showing the strongest age dependence (R² = 0.61). Conclusion: Visual and auditory reaction times vary significantly with age, following a developmental improvement through young adulthood followed by a progressive age-related decline. Auditory stimuli are processed faster than visual stimuli across all age groups, and choice reaction tasks are more sensitive than simple reaction tasks in detecting age-related sensorimotor slowing.

Functional Outcomes of Intramedullary Nailing Versus Plating in Tibial Shaft Fractures: A Prospective Comparative Study
Pages 104 - 110

View PDF
Abstract
Background: Tibial shaft fractures are among the most common long bone injuries, and intramedullary nailing (IMN) and plating remain the two principal operative options. While both achieve high union rates, debate continues regarding which technique offers superior functional recovery. Objective: To prospectively compare functional outcomes, radiological alignment, time to union, and complication rates between intramedullary nailing and plate osteosynthesis in adults with tibial shaft fractures. Methods: This prospective comparative study included 80 adult patients with closed or Gustilo–Anderson type I/II open tibial shaft fractures, allocated to intramedullary nailing (n=40) or plating (n=40). Patients were followed for a minimum of 12 months. Functional outcome was assessed using the Lower Extremity Functional Scale (LEFS), the American Orthopaedic Foot and Ankle Society (AOFAS) score, and the Johner–Wruhs criteria; radiological union and alignment were assessed on serial radiographs. Results: Intramedullary nailing was associated with significantly shorter operative time (58.6 vs 82.4 minutes, p<0.001), less blood loss (78.5 vs 142.6 mL, p<0.001), and faster radiological union (17.2 vs 20.6 weeks, p<0.001). Mean LEFS scores at 12 months were significantly higher in the nailing group (78.6 vs 74.2, p=0.005), although knee range of motion and anterior knee pain were less favourable in this group. Plating achieved superior coronal and sagittal alignment (p<0.05 for both). Overall excellent/good outcomes by Johner–Wruhs criteria were comparable between groups (85.0% vs 82.5%, p=0.769), and complication rates did not differ significantly. Conclusion: Both intramedullary nailing and plating provide satisfactory functional outcomes in tibial shaft fractures. Nailing offers faster recovery, shorter surgery, and earlier union, while plating provides superior anatomical alignment with less anterior knee pain. The choice of fixation should be individualised based on fracture pattern, soft tissue status, and patient-specific factors.

Abstract
Background: Management of neck metastasis of unknown origin (NMUO) continues to represent a major diagnostic and therapeutic challenge in head and neck oncology. Although most patients present with metastatic squamous cell carcinoma involving cervical lymph nodes, NMUO comprises a heterogeneous group of malignancies with varied pathological characteristics and biological behavior. Advances in imaging, endoscopic evaluation, immunohistochemistry, and molecular diagnostics have significantly improved the ability to localize occult primary tumors; however, considerable controversy and variation still exist regarding optimal diagnostic strategies and treatment approaches. Methods: This study was conducted as a narrative literature review aimed at summarising current evidence on the evaluation and management of neck metastasis of unknown origin (NMUO). Results: Modern evaluation of NMUO involves a multidisciplinary and stepwise approach integrating clinical examination, fibreoptic endoscopy, cross-sectional imaging, PET-CT, ultrasound-guided fine needle aspiration cytology, and histopathological confirmation. Core needle biopsy has emerged as an important adjunct in cases with non-diagnostic cytology, enabling improved tissue architecture assessment and molecular analysis. The increasing role of immunohistochemistry, HPV and EBV testing, in-situ hybridization, and next-generation sequencing has enhanced identification of likely occult primary sites, particularly within the oropharynx and nasopharynx. Advanced endoscopic techniques such as narrow band imaging, transoral laser microsurgery, and transoral robotic surgery with lingual tonsillectomy have further improved primary tumor detection rates. Treatment strategies are individualized according to nodal stage, pathological risk factors, viral status, and identification of the primary tumor, and include combinations of surgery, radiotherapy, and chemoradiotherapy. Contemporary approaches increasingly favour treatment de-escalation in selected HPV-associated disease while maintaining excellent oncologic outcomes. Conclusions: Management of NMUO requires a structured and comprehensive diagnostic approach supported by modern imaging, pathological, molecular, and minimally invasive surgical techniques. HPV and EBV status have become central to both localization of the occult primary and therapeutic decision-making. Although substantial progress has been achieved in diagnostic yield and treatment outcomes, significant variability persists among institutions regarding optimal evaluation and management protocols. Continued collaborative research and multicenter studies are necessary to establish greater consensus and refine individualized treatment strategies for patients with NMUO.

Abstract
Background- Recurrent aphthous stomatitis (RAS) is a very common condition characterized by recurrent painful oral ulcers, which significantly affect the quality of life in affected patients. Despite its high prevalence, the etiology and optimal management of RAS remain elusive. A variety of therapeutic interventions, from topical and systemic treatments to newer approaches such as laser therapy, probiotics, and plant-based therapies, have been pursued. Objective: This systematic review aims to analyze the published evidence on the diagnosis and treatment of RAS, in terms of discovering effective interventions and gaps in the literature. Methods- RCTs on diagnosis or treatment of RAS were included. A systematic search was conducted across six databases: PubMed, Scopus, Embase, Web of Science, Cochrane Library, and CINAHL, employing Boolean operators and MeSH terms. Data were independently extracted by two reviewers; these included study characteristics, population demographics, interventions, outcomes, and statistical methods. The risk of bias was assessed employing the Cochrane Risk of Bias 2.0 tool. Results- A total of ten RCTs was included, ranging between diverse interventions such as probiotics, laser therapy, systemic drugs, and plant-based therapies. Commonly analyzed main outcomes included pain reduction as well as ulcer size, while some studies of healing time, recurrence rates, and complete remission took place. Pain and ulcer size reduced the most significantly in laser therapy, probiotics, and topical agents like zinc sulfate and caffeic acid. Vitamin B12 significantly decreased recurrence rates and reached a high ulcer-free status. Multivitamin supplementation was devoid of significant effects. The vast majority of studies reported no adverse events; however, systemic drugs such as thalidomide and dapsone were accompanied by well-known toxicities. Statistically, the methods utilized were Mann-Whitney U, Friedman tests, and advanced models such as ANCOVA in order to strengthen the analysis. Conclusion- This review demonstrated that advanced treatments, including laser therapy, probiotics, and natural compounds, are effective for the treatment of RAS, so promising alternatives emerge for currently used methods. Systemic drugs still prevail in extreme cases but are limited by side effects. The results highlight the imperatives of personalized therapeutic strategies and high-quality research to promote optimization in the management of RAS

The need for information regarding dental trauma
Pages 70 - 73

View PDF
Abstract
According to WHO, 16% to 40% of children aged 6 to 12 suffer a dental trauma.1This means that almost half of all children are likely to suffer a traumatism involving one or more teeth, during daily activities like playing and sports. In this age group, children have a mixed dentition, with both deciduous and permanent teeth. However, the chronology of permanent teeth eruption places the permanent maxillary central and lateral incisors in the beginning of this time period, around the age of 8.2 This fact, corroborated with their placement in the most anterior position, make them the permanent teeth most likely to be affected in a traumatism involving the oral region.

Abstract
Introduction C. neoformansis a major cause of disease in immunocompromised hosts, especially people living with HIV/AIDS. In the last decade, there have been increasing reports of cryptococcal disease in immune competent patients, for whom no definitive diagnostic algorithm, therapeutic options and prognostic data are available. Methods This is a retrospective study conducted at a tertiary care hospital over a period of 6 years, analysing and comparing the clinical presentation, risk factors, laboratory findings, evolution, outcomes and prognosis of confirmed cases of cryptococcal disease in immunocompromised and immune competent patients. Results During the study period, a total of 20 patients with cryptococcal disease were identified (8 immune competent and 12 immunocompromised). The median time to diagnosis was much longer in immune competent patients compared to immunocompromised patients, 90 (15-110) days and 20 (7-75) days respectively (p=0.019). CSF findings were similar between the 2 groups except that mean CSF protein levels were significantly lower (78.5±15.1 mg/dL) in immune competent patients compared to immunocompromised patients (181.9±150.9 mg/dL) (p=0.036). Serum cryptococcal antigen was positive in all patients. A total of 83.3% patients in the immune competent group and all patients in the immunocompromised group had satisfactory outcome at the time of discharge and follow up over a period of 12 months. Conclusion Cryptococcal disease is not uncommon in immune competent hosts and diagnosis is usually delayed because of a low index of clinical suspicion. Serum cryptococcal antigen could serve as a valuable screening test. Despite the fact that we found no significant differences in terms of outcome between the two groups (p=0.400), the median time to diagnosis was much longer in the immune competent group compared to the immune compromised group, which emphasizes the need for clinical awareness of this entity in immune competent patients.

Abstract
Introduction The prevalence of malnutrition or undernutrition in hospitalized adults is estimated to be around 31.4% in the USA and European countries. Patients who require hospitalization for infectious diseases make up a particular type of patient population, at risk for malnutrition either due to the catabolic processes, generalized inflammation and higher nutrient demand associated with infection, or to the direct action of the infectious agent itself, such as in infectious diarrhea, malabsorption and external losses. MethodsWe performed a cross-sectional study to screen for the risk of malnutrition in the first 24 hours following hospital admission in a population of adult patients admitted to a national reference center for infectious diseases in Bucharest, Romania, using the Malnutrition Universal Screening Tool (MUST) and a standardized medical questionnaire. ResultsThe study included 211 patients with a median (interquartile range – IQR) age of 52 (33-68) years, and a male-to-female ratio of 1:1.7. The median (IQR) duration of hospitalization was 6 (4-10) days, and the median (IQR) number of drug classes required during hospitalization, 2 (0, 3). The number of previous hospitalizations during the past 12 months ranged from 0 (24.2%) to 5 (1.9%), most patients (42.7%) presenting one recent previous hospital admission. Overall, 22.7% of those included in the study presented a risk of malnutrition (5.7% medium risk and 17% high risk). Malnutrition was most common (50%) in patients admitted for viral upper respiratory tract infections, followed by HIV infection and meningitis (33.3% each). The MUST score was directly dependent on patient age (p=0.030), number of previous hospitalizations during the past 12 months (p=0.002), number of drug classes required for treatment (p=0.034), and duration of the current hospital admission (p=0.029), a high risk of malnutrition associating a 1.4 days increase in the mean length of hospital stay (p=0.041) in our patient group. Conclusion In conclusion, we have reported the overall malnutrition risk in Romanian patients hospitalized for infectious diseases, while identifying the main patient categories and types of infections that associate higher malnutrition risk, findings which can substantiate future national screening policies.

Abstract
Introduction Subsequent to the devastating flood in Chennai, South India, in November and December 2015, an increase in the number of cases of melioidosis was noted. Case series We performed a retrospective chart review of patients with melioidosis to analyze the clinical profile and the association with flood water exposure. All patients with blood or any other sterile site specimen growing Burkholderia pseudomallei between 9 November 2015 and 8 January 2016 were studied. Twelve patients with blood culture growing B. pseudomallei were identified during this two-month period. All were from the flood affected area and 11 had definite flood water exposure, and the majority had diabetes as comorbidity. The time period from exposure to onset of symptoms ranged between 5 to 24 days. All patients presented with fever, 3 had pneumonia and 8 had septic foci elsewhere. All had bacteremia, 4 had one other culture positive site. Overall, 33% mortality was noted. Conclusion Following the flooding season there was an increase in melioidosis cases with a definite association with flood exposure. Understanding the epidemiology, rainfall and flood exposure as risk factors is important for early identification of these cases.
