RESUMEN

Introduction: Soft-tissue chondromas are rare, benign cartilaginous tumors predominantly affecting the extremities, often diagnosed in middle-aged individuals without a clear sex predilection. Despite their benign nature, these tumors can pose significant diagnostic challenges due to their slow growth, asymptomatic nature, and potential for mimicking other soft-tissue tumors. Case Report: We report a case of a 27-year-old male with an 8-year history of a progressively enlarging mass on the dorsal aspect of the second toe of the left foot, leading to pain, difficulty in walking, and wearing shoes. Initial clinical examination revealed a firm, non-tender swelling with hypoesthesia over the affected area. Radiographic findings suggested a soft-tissue mass with stippled calcification, while magnetic resonance imaging indicated a large altered signal intensity lesion abutting but not arising from the bone. Fine needle aspiration cytology hinted at a benign mixed tumor/chondroid syringoma. An excisional biopsy was performed, revealing a well-circumscribed tumor with lobules of mature hyaline cartilage, consistent with a diagnosis of soft-tissue chondroma. Post-operative period recovery was uneventful except for local flap necrosis which was managed with skin grafting. There was no recurrence at the 1-year follow-up. Conclusion: Soft-tissue chondromas, while rare and benign, can significantly impact patients' quality of life. Correct diagnosis, involving a comprehensive evaluation and histopathological confirmation, is crucial for effective management and prevention of unnecessary interventions. This case adds valuable insight into the clinical presentation, diagnostic challenges, and management strategies for soft-tissue chondromas.

RESUMEN

The liver, a pivotal organ in human metabolism, serves as a primary site for heme biosynthesis, alongside bone marrow. Maintaining precise control over heme production is paramount in healthy livers to meet high metabolic demands while averting potential toxicity from intermediate metabolites, notably protoporphyrin IX. Intriguingly, our recent research uncovers a disrupted heme biosynthesis process termed 'porphyrin overdrive' in cancers that fosters the accumulation of heme intermediates, potentially bolstering tumor survival. Here, we investigate heme and porphyrin metabolism in both healthy and oncogenic human livers, utilizing primary human liver transcriptomics and single-cell RNA sequencing (scRNAseq). Our investigations unveil robust gene expression patterns in heme biosynthesis in healthy livers, supporting electron transport chain (ETC) and cytochrome P450 function without intermediate accumulation. Conversely, liver cancers exhibit rewired heme biosynthesis and a massive downregulation of cytochrome P450 gene expression. Notably, despite diminished drug metabolism, gene expression analysis shows that heme supply to the ETC remains largely unaltered or even elevated with patient cancer progression, suggesting a metabolic priority shift. Liver cancers selectively accumulate intermediates, which are absent in normal tissues, implicating their role in disease advancement as inferred by expression analysis. Furthermore, our findings in genomics establish a link between the aberrant gene expression of porphyrin metabolism and inferior overall survival in aggressive cancers, indicating potential targets for clinical therapy development. We provide in vitro proof-of-concept data on targeting porphyrin overdrive with a drug synergy strategy.

RESUMEN

Heme, an iron-containing tetrapyrrole, is essential in almost all organisms. Heme biosynthesis needs to be precisely regulated particularly given the potential cytotoxicity of protoporphyrin IX, the intermediate preceding heme formation. Here, we report on the porphyrin intermediate accumulation within the tumor microenvironment (TME), which we propose to result from dysregulation of heme biosynthesis concomitant with an enhanced cancer survival dependence on mid-step genes, a process we recently termed "Porphyrin Overdrive". Specifically, porphyrins build up in both lung cancer cells and stromal cells in the TME. Within the TME's stromal cells, evidence supports cancer-associated fibroblasts (CAFs) actively producing porphyrins through an imbalanced pathway. Conversely, normal tissues exhibit no porphyrin accumulation, and CAFs deprived of tumor cease porphyrin overproduction, indicating that both cancer and tumor-stromal porphyrin overproduction is confined to the cancer-specific tissue niche. The clinical relevance of our findings is implied by establishing a correlation between imbalanced porphyrin production and overall poorer survival in more aggressive cancers. These findings illuminate the anomalous porphyrin dynamics specifically within the tumor microenvironment, suggesting a potential target for therapeutic intervention.

RESUMEN

This prospective cohort study examined the changes in airway area and soft tissue parameters following interpositional arthroplasty for temporomandibular joint (TMJ) ankylosis. Ten patients with TMJ ankylosis underwent surgery, and preoperative and postoperative skeletal and soft tissue measurements were obtained. A significant rise in soft tissue parameters was observed following surgery, although only minor changes in skeletal parameters were seen. The nasoropharyngeal area, oral area, soft palate area, and tongue area were examined. After the surgery, increases in values were observed in the nasoropharyngeal area (from 3482.4 mm2 to 3618.7 mm2), the oral area (from 2731.8 mm2 to 2840.8 mm2), the soft palate area (from 204.9 mm2 to 217.3 mm2), and the tongue area (from 2577.5 mm2 to 2600.8 mm2). These findings suggest that interpositional arthroplasty can improve airway area and soft tissue dimensions, affecting the stomatognathic system's aesthetic and functional aspects. Further research is needed to validate these results and assess long-term stability.

RESUMEN

Background: Lower gut bleeding is an alarming sign among caregivers. Determining the etiology is of utmost importance for further management. This is the first study conducted in northernmost India. Methods: This cross-sectional study was conducted at the Department of Pediatrics, Government Medical College, Srinagar. This study aimed to describe the etiology of lower gastrointestinal bleeding in the age group of 1-18 years over the past 5 years from June 2017 to June 2022. Results: A total of 310 children presented with hematochezia (53.5%), blood mixed with loose stools for > 2 weeks (39.3%), melena (1.9%), and occult blood in stools (0.3%). The mean age was 5.12 years. The age group of 1-6 years was 73.5 %. The most common findings were rectosigmoid polyps n=104 (33.5%), anal fissure n=47 (15.1%), lymphoid nodular hyperplasia (LNH) n=38 (12.2%), trichuris dysentery syndrome n=30(9.7%), cow's milk protein allergy n=27(8.7%), non-specific colitis n=18(5.8%), solitary rectal ulcer syndrome n=14(4.5%), inflammatory bowel disease n=6 (1.9%),intestinal tuberculosis n=3(0.9%), duodenal dieulafoy lesion 1(0.3%), and blue bleb nevus rubber syndrome n=1(0.3%). 21 patients had a normal colonoscopy. The colonoscopy yield was 93.3 %. Among the colonoscopy-negative patients, 6(1.6%) had Meckel's diverticulum, and 1(0.3%) had a duodenal dieulafoy lesion. Conclusion: Lower GI bleeding most commonly presents as hematochezia, and the most common cause is a rectosigmoid polyp. Colonoscopy is the procedure of choice to evaluate the etiology of lower GI bleeding. Anal fissures, LNH, Trichuris trichiura, and cow's milk protein allergy are other common causes of lower gut bleeding in Kashmir, northernmost India.

RESUMEN

Introduction: Temporomandibular joint (TMJ) ankylosis is a debilitating condition usually afflicting children and young adults, causing long-term functional, aesthetic, and severe psychological impacts on the lives of these patients. Objective: To compare the postoperative outcomes after using one of the most commonly employed inter-positional graft, i.e., temporalis fascia, and a recently introduced 'more suitable' graft, i.e., dermal fat. Methods: A prospective study in which 20 patients of TMJ ankylosis were randomly assigned into two groups of 10 patients each. Temporalis fascia was used as an inter-positional graft in one group, while dermal fat graft was used in the other group. Post-surgical clinical parameters were evaluated, including interincisal mouth-opening and pain. Results: Interincisal mouth opening at six months was greater in group A (32.1 ± 12.93) as compared to group B (33.8 ± 4.89), but statistically, it was not significant (P = 0.478). The mean pain score in group A was 4.60 ± 1.17, 1.50 ± 0.70, 0.20 ± 0.42 on day 1, 7, and 15, respectively. The mean pain score in group B was 4.10 ± 0.99, 1.30 ± 0.48, 0.20 ± 0.42 on day 1, 7, and 15, respectively. Conclusion: Both the graft materials work well in terms of maximum interincisal opening. For more clarification, a larger sample size with a longer duration of follow-up is needed to validate the study.

RESUMEN

Introduction: Hyperbaric oxygen therapy (HBOT) has emerged as an adjunct treatment modality in various orthopedic and rheumatological conditions. Undersea and Hyperbaric Medical Society (UHMS) defined the minimum number of HBOT cycles, dose, and frequency for various diseases. UHMS laid the 14 absolute indications for HBOT. This article deals with the mechanism of actions of HBOT and evidence of various musculoskeletal disorders where HBOT was utilized to accelerate the healing process of the diseases. Materials and methods: The review literature search was conducted by using PubMed, SCOPUS, and other database of medical journals for identifying, reviewing, and evaluating the published clinical trial data, research study, and review articles for the use of HBOT in musculoskeletal disorders. Results: Various clinical researchers documented cellular and biochemical advantages of HBOT which possess allodynic effects, anti-inflammatory, and prooxygenatory effects in patients with musculoskeletal conditions. Studies on the usage of HBOT in avascular necrosis and wound healing provide a platform for exploring the plausible uses of HBOT in other musculoskeletal conditions. Literature evidence states the complications associated with HBOT therapy. Conclusion: The existing HBOT protocols have to be optimized for various musculoskeletal disorders. Large scale blinded RCTs have to be performed for demonstrating the level of evidence in the usage of HBOT in various musculoskeletal clinical scenarios.

RESUMEN

STUDY DESIGN: Systematic Review and Meta-analysis. OBJECTIVES: This systematic review and meta-analysis is aimed to assess effectiveness, safety, clinical, functional and radiological outcome of either combined anteroposterior or posterior-only approach in the surgical management of active tubercular disease of paediatric thoracolumbar spine. METHODS: A systematic literature search through PubMed, Scopus, Web of Science and Cochrane Library database was performed. Data extraction was undertaken following methodological quality assessment. RESULTS: 9 out of the 182 publications identified, were included for analysis. A total of 247 patients were analysed. Two amongst the 9 studies were retrospective comparative studies evaluating posterior approach with combined anteroposterior approach and were considered for comparative meta-analysis. Blood loss and duration of surgery was significantly higher in the anteroposterior group, as compared to the posterior-only group. There was no significant difference between the 2 groups in terms of post-operative kyphosis angles, final kyphosis angles, number of complications, functional outcome and spinal fusion time. However, all the included studies were non-randomised and retrospective. Only 2 of them had a control group with a high heterogeneity amongst these 2 studies. CONCLUSION: The inference from the studies included in this review suggests that equivalent results can be achieved with posterior-only approach for thoracolumbar tuberculosis in children as compared to anteroposterior approach, with much lower complexity, reduced blood loss and shorter surgical time. However, due to the high risk of bias and considerable heterogeneity among the studies included, we cannot conclude whether one approach is better than the other.

RESUMEN

Introduction: Achieving accurate anatomic reduction and stable internal fixation is mandatory in the management of femoral neck fractures (FNF) in adults. The spatial configuration and direction of the screws have been reported to provide stability to the fracture. The study's goal is to analyse the clinico-radiological outcome of the newer biplane double-supported screw fixation (BDSF) technique in the Indian cohort. Materials and methods: Patients with isolated FNFs underwent osteo-synthesis by BDSF technique. Radiological outcome was evaluated by time to union and fracture healing on plain radiographs. Clinical outcome was measured using the Harris hip score (HHS) at 1, 3, 6, and 12 months after surgery. The pain reduction was measured using the VAS score. Results: Twenty-seven patients with a mean age of 37.33 ± 9.84 years (24-55 years) were followed up for at least 12 months (12-31 months). The mean HHS at 12 months was 94.81 ± 8.18 (range: 68-100). Twenty-five patients were able to achieve radiological union within a mean time of 14.60 ± 4.69 weeks (range: 8-28). The overall complication rate was found to be 18.51% (5 out of 27 patients). Individual complications were non-union (2 patients; 7.4%), AVN (3 patients; 11.11%), and screw back out with femoral neck shortening (4 patients; 14.81%). Conclusion: Screw configuration using the BDSF technique provides a good union rate with minimum complications. The majority of patients resulted in a good (HHS >80) to excellent functional outcome. Based on the clinico-radiological outcome obtained, we conclude that this technique is effective in the fixation of FNF in adults. Level of study: Level II.

RESUMEN

Introduction: The treatment of temporomandibular joint is mainly surgical and aims at restoring the function of joint and correcting the aesthetics deformity caused by ankylosis. Studies are available in the literature which showed that there is osteogenic potential in condylar stump remaining after gap arthroplasty, especially in children. Our objective was to assess the growth of ramus operated after surgery using orthopantomogram as the tool of assessment. Materials and method: Fifteen patients of prospective study design were selected for study. This study was undertaken to evaluate the mandibular ramal growth in TMJ ankylosis patients treated without growth center transplantation using orthopantomogram as a tool of assessment. Results: Mean ramal length of the operated right side was found to be 42.02 mm in immediate postoperative, 43.18 mm in sixth month postoperative and 44.57 mm in 1 year postoperative follow-up. Mean ramal length of the operated left side was found to be 40.15 mm in immediate postoperative, 42.10 mm in sixth month postoperative and 44.80 mm in 1 year postoperative follow-up. Conclusion: Our investigations showed that mandibular growth rate increases after successful treatment of ankylosis in children. One drawback of this treatment protocol that we observed was that the total growth deficit manifested in all our patients could not be made up.

RESUMEN

Medicinal plants are highly used in the ethnoveterinary practice as considerable livestock resources in remote areas. The aim of the present study is to explore the ethnoveterinary medicinal practices in three different communities and discuss the cross-cultural consensus on the usage of medicinal plants for the treatment of animals. The field survey was conducted by the animal healers of the area during the different seasons of plant growth. A total of 83 informants were interviewed through Semi-structured interview involving experts of traditional knowledge in 21 localities of the three regions (Zhob, D. I. Khan and Mianwali) were conducted. Findings of the study were quantitatively analyzed through the informant consensus factors to identify the homogeneity information provided by the informants. Furthermore, cross-culture consensuses were analyzed and recorded data were represented in a tabulated and Venn diagrams. In particularly, 59 species of plants were documented in the comparative analysis. Among them, 32 plant species were recorded in Pashto community, while Punjabi and Sarakai communities exhibited nine and four plant species, respectively. Whereas cross-cultural analysis showed 14 medicinal plants that were commonly utilized by three different ethnic communities, that indicated low interregional consensus in regard to ethnoveterinary practices of medicinal plants. The current study showed that different communities and ethnic groups sharing some traditional knowledge and cross-culturally approaches have been reported from traditional uses of plants against livestock's diseases. Therefore, current findings are the opportunities to scrutinize the plants for the discovery of new drug sources for humans and animals.

RESUMEN

BACKGROUND: This study was conducted to see the frequency of hormone receptors and Her-2/Neu positivity in different histology in breast cancer patients. METHODS: It was a cross-sectional study conducted at the Department of Medical Oncology, Jinnah Postgraduate Medical Centre from June 2018- March 2019. Total 373 patients of age 22-81 years of which 360 female and 13 males, with histopathological proven diagnosis of breast cancer were included in the study using non-probability consecutive sampling technique. The immunohistochemistry (IHC) was performed on biopsy sample for the status of PR, ER and HER-2/Neu and the confirmation of Her-2/Neu was done by Fluorescent In situ Hybridization (FISH) technique if HER-2/Neu was equivocal by IHC testing. Information regarding demographics, family history, histology, grade, stage, metastatic site and other histopathological parameters were noted on predesigned proforma by the researcher. SPSS-23 was used to analyse data. RESULTS: Total of 373 patients were included in the study. The mean patient age was 45.34±12.28 years. ER, PR, Her 2 Neu (IHC) & Her 2 Neu (FISH) were found positive in 206 (55.2%), 182 (48.8%), 121 (32.4%) & 23 (6.2%) patients, respectively. The histology with PR receptor & grade of tumour with ER & PR receptor showed statistical significance (p<0.05). CONCLUSIONS: ER, PR & HER-2/NEU expressions in breast cancer vary among different population and it is very important to find out the frequency among different histopathological types as it is of predictive and prognostic value. So, it is recommended to look for these markers and treat them accordingly.

RESUMEN

Management of temporomandibular joint (TMJ) ankylosis is mainly through surgical intervention. Interpositional materials are a necessity when it comes to prevention of TMJ re-ankylosis after arthroplasty. Early aggressive postoperative physiotherapy is essential for the prevention or treatment of TMJ hypomobility or ankyloses. Recently, it has been shown that abdominal dermis fat helps promote smooth, pain-free joint function and it is stable after interposition and less prone to fragmentation. The purpose of this study was to assess that whether dermal fat is a good choice of interpositional material when it comes to decreased pain perception during aggressive physiotherapy after release of ankyloses thus ensuring good compliance by the patient. We also assessed the fate of the graft material on computed tomography to evaluate any volume changes if occurred after interposition.

RESUMEN

BACKGROUND: Acute myeloid leukaemia (AML) is malignant neoplasms of myeloid cells categorized by clonal expansion of hematopoietic blasts of myeloid lineage in peripheral blood and bone marrow. The aim of current study is to identify the common cytogenetic abnormalities in AML patients presenting at a tertiary care hospital of Pakistan. METHODS: It was a cross-sectional study conducted at the department of Medical oncology of the Jinnah Postgraduate Medical Center, Karachi from Jun 2017- Jan 2019. The non-probability consecutive sampling technique was used to select patients. Total 92 cases of AML of age 15-55 years of either gender were included in the study. The detection of cytogenetic abnormality was done on the bone marrow biopsy. The cytogenetic abnormalities were classified into the three cytogenetic risk groups as favourable, intermediate and unfavourable. For analysis of data SPSS 23 version was used. RESULTS: The cytogenetic abnormalities were detected in 34 (37%) of the AML patients while 58 (63%) patients had normal cytogenetic. Thirty-two females (34.8%) had a normal cytogenetic (46; XX), and 15 females (16.3%) had various cytogenetic abnormalities. Twenty-six males (28.3%) had normal cytogenetic (46; XY) and 19 males (20.7%) had various cytogenetic abnormalities. Most of the patients were in intermediate risk group (67.4%), followed by favourable (17.4%) and unfavourable risk group (15.2%). The most frequent chromosomal abnormalities observed were complex cytogenetic which was detected in 5 AML patients. CONCLUSIONS: In the present study cytogenetic abnormalities were found in 37% of AML patients. Sixty-seven of the AML patients were in intermediate risk group and five patients had complex cytogenetic. Hence the cytogenetic analysis provides significant information regarding prognosis of AML patients and the cytogenetic abnormalities are less than international literature.

RESUMEN

BACKGROUND: This study was conducted to determine the frequency of amenorrhea after chemotherapy among breast cancer patients". METHODS: Total 201 premenopausal females (having menstruation during the past 6 months at the time of diagnosis) of age 15-45 years and had confirmed diagnosis of breast cancer requiring chemotherapy were included in the study using non-probability consecutive sampling technique. Amenorrhea within 6 months after the completion of chemotherapy was labelled as chemotherapy induced amenorrhea. Data was entered and analysed using SPSS-23. RESULTS: The mean age of the patients was reported as 37.06±5.68 years. Majority of the females were married (86.6%) & multigravida (81.1%). Most of the patients (23.9%) received neoadjuvant chemotherapy followed by surgery and radiotherapy. A total of 129 patients received Adriamycin plus cyclophosphamide followed by paclitaxel as chemotherapy regimen. Out of 201 females, 184 (91.5%) experienced amenorrhea after start or completion of chemotherapy. CONCLUSIONS: The frequency of CIA was very high among breast cancer patients in our study, long term follow-up is needed to see input of CIA on future fertility.

RESUMEN

OBJECTIVE: To evaluate the response rate of Cisplatin plus Docetaxel in the treatment of locally advanced head and neck squamous cell carcinomas (HNSCC) at a tertiary care hospital in Karachi, Pakistan. MATERIALS AND METHODS: It was a longitudinal study, conducted at the Department of Medical Oncology, Jinnah Postgraduate Medical Center, Karachi, Pakistan from December 2018 to June 2019. One hundred patients of age 14-66 years of age of either gender with histologically proven Squamous Cell Carcinoma of Head and Neck, Stage III and IV (locally advanced) with no distant metastases were included in the study. Patients who were declared unresectable by the otolaryngologist and those with delayed appointment for radiation were given 3 cycles of Induction Chemotherapy with Cisplatin and Docetaxel, both at a dose of 75mg/m2 3 weekly. After 3 cycles, CT scan was repeated to assess the clinical response. Those patients who had partial or complete response as per RECIST criteria were re-assessed by the otolaryngologist and were planned for surgery if disease became resectable while other patients were referred for Concurrent Chemo-Radiation Therapy (CCRT). SPSS version 23 was used to analyze data. RESULTS: The partial response was achieved in majority of the patients after Induction Chemotherapy with Docetaxel and Cisplatin (62%) with a complete response in 12 %. However, 22% showed progression of the disease, and 4% showed stable disease. The most frequent side effects observed were diarrhea (62%) and neutropenia (57%). CONCLUSION: Induction chemotherapy with Cisplatin and Docetaxel is a promising regimen with good response and favorable toxicity profile and can be considered as a potentially effective outpatient regimen for locally advanced squamous cell carcinoma of head and neck.

RESUMEN

BACKGROUND: Acute life threatening metabolic acidosis in exclusively breast fed infants due to thiamine deficiency is not described. Kashmir valley, a north Indian state has a population that largely consumes polished rice. METHODS: A six months prospective descriptive study of infants who presented with acute life threatening metabolic acidosis (Blood pH ≤ 7.0) due to thiamine deficiency. RESULTS: Twenty three infants (Eleven male; Twelve female) in the age range of 32 days to 4 months had a pH of ≤7 at admission. Onset of moaning was immediate (2-24 hours). Blood lactate levels were more than 15mmol/L. Blood thiamine levels of six infants in whom it was done ranged from 11-69 nmol/L (control 78-185 nmol/L). All infants were exclusively breast fed. Maternal staple diet consisted of polished rice. All mothers consumed rice after washing it thrice. Twelve lactating mothers were on customary dietary restrictions. Practice of straining rice after cooking was observed in thirteen. The commonest symptoms were irritability (82%) and reflux (56%). Commonest signs were tachycardia (100%) and moaning (73%). At presentation 52% were in cardiogenic shock. Response to thiamine was dramatic with moaning and irritability subsiding in two hours and tachycardia in four hours. Adequate perfusion was achieved in one hour. Eighteen patients seen at six months follow up had normal neurodevelopment. CONCLUSIONS: Thiamine deficiency in an infant can present as sudden onset metabolic acidosis. If treated early, metabolic acidosis due to thiamine deficiency is associated with good immediate and long term prognosis even if pH is less than 7 at presentation.

RESUMEN

Neuroblastoma is the most common intra-abdominal and extracranial solid tumour in children, accounting for 7%-8% of all childhood cancers. It is a malignant tumour of the autonomic nervous system derived from the neural crest. Most children with neuroblastoma have distant metastatic disease at the time of diagnosis. Pulmonary metastasis at the time of diagnosis is rare, and rarer is the presence of associated pleural effusion.

RESUMEN

OBJECTIVE: To determine the incidence and outcome of acute kidney injury (AKI) in hospitalized patients. DESIGN: Prospective, observational. SETTING: Tertiary care center in North India. PARTICIPANTS/PATIENTS: Inpatients, 1 month to 18 yrs. INTERVENTION: None. MAIN OUTCOME MEASURES: Incidence of AKI based on the serum creatinine criteria proposed by the AKI Network. RESULTS: During February to September 2008, thirty nine of 108 (36.1%) critically ill patients and 34 of 378 (9.0%) patients who were not critically ill developed AKI (P<0.001); the respective incidence densities were 45.1 and 11.7 cases/1000 patient days, respectively. The maximal stage of AKI was stage 1 in 48 (65.8%) patients, stage 2 in 13 (17.8%) and stage 3 in 12 (16.4%) patients; 11 (15.1%) required dialysis. Patients with AKI had a significantly longer duration of hospital stay (9 days vs 7 days, P<0.02) and higher mortality (37% vs 8.7%; hazard ratio, HR 2.73; 95% CI 1.64, 4.54). Independent risk factors for AKI were young age (HR 0.89; 95% CI 0.83, 0.95), shock (HR 2.65; 95% CI 1.32, 5.31), sepsis (HR 3.64; 95% CI 2.20, 6.01), and need for mechanical ventilation (2.18; 95% CI 1.12, 4.26). Compared to patients without AKI, the mortality was higher for AKI stage 2 (HR 5.18; 95% CI 2.59, 10.38) and stage 3 (HR 4.34; 95% CI 2.06, 9.16). Shock was an independent risk factor for mortality (HR 10.7; 95% CI 4.96, 22.98). CONCLUSIONS: AKI is common in critically ill children, especially younger patients with septicemia and shock, and results in increased hospital stay and high mortality.

RESUMEN

OBJECTIVE: To describe the clinical characteristics and outcome of Indian children infected with 2009 H1N1 influenza virus. STUDY DESIGN: Retrospective chart review. SETTING: Outpatient department and hospitalized patients in a tertiary care hospital. METHODS: Clinical details of 85 children (positive for the 2009 H1N1 virus infection tested by real time reverse transcriptas epolymerasechain reaction assay) were analyzed from medical charts. RESULTS: Of the 85 (55 boys) children positive for 2009 H1N1 virus infection, 64.7%were between 5 years to 16 years, and 35.3%were below 5 years age. The mean age of these children was 7.5±3.5 yr. Contact history was positive only in 22 (26%) cases. High grade fever was the most common symptom, followed by cough and rhinorrhea. Twenty-nine (34%) patients had an underlying co-morbid condition. Of the 34 patients who underwent chest radiography during evaluation, 18 children (52.9%) had findings consistent with lower respiratory tract infection. Antiviral therapy was initiated in 76 patients. Hospitalization was required in 30 (35.3%) children. Risk factors for hospitalization included underlying co-morbid condition, respiratory distress, vomiting, wheezing, diarrhea, hypotension and infiltrates/consolidation on chest radiograph. Mean length of hospitalization was 131±76 hours, irrespective of underlying disease. Three children developed Acute Respiratory Distress Syndrome and died. CONCLUSIONS: Clinical features and routine laboratory investigations in children with swine origin influenza were non-specific. Children with co-morbid condition, respiratory distress, vomiting, wheezing, diarrhea, hypotension and infiltrates/consolidation on chest radiograph were at higher risk of hospitalization.
