ABSTRACT
Salivary duct carcinoma is a rare and aggressive salivary gland malignancy with a poor prognosis. Due to the paucity of literature, very little is known about this neoplasm. We have described such a case in this case report and highlighted the clinical and histopathological features associated with this disease. A sixty-year old male patient reported in the outpatient department of a regional dental college and hospital with a circular firm growth in the mandibular anterior region and mobility of adjacent mandibular teeth. An array of investigations including radiographic, tomographic, ultrasonographic as well as histopathological were performed. It was diagnosed as invasive salivary duct carcinoma with distant metastases in the shoulder joint, ribs as well as pelvic bones. Currently, no National Comprehensive Cancer Network guidelines for the specific treatment of salivary duct carcinomas exist. National Comprehensive Cancer Network guidelines recommend complete surgical excision of tumors for major salivary gland tumors without nodal involvement (N0) with or without neck dissection for high-grade and T3/T4 salivary gland tumors.
ABSTRACT
Post-operative pain, discomfort, and trismus are common postoperative complications after surgical extraction of third molars. Various therapeutic approaches like prescribing analgesic drugs, corticosteroids, and Non-steroidal anti-inflammatory drugs are followed to reduce these complications. Photo-biomodulation therapy (PBMT) utilizes a monochromatic light source that shows effects in all phases of inflammation by reducing edema, redness, heat, and pain. In vivo studies were searched to evaluate postoperative pain levels in patients who underwent photo-biomodulation therapy following extraction of impacted third molars. A comprehensive search was done from January 2023 to July 2023 in PubMed electronic databases. In addition, a manual search of the references mentioned in the studies and gray literature was done. The literature search yielded a total of 157 studies through a search in the electronic database PubMed. Among all the studies, 51 duplicate records were removed. Ninety-seven studies were removed after screening of titles and abstracts. A total of 9 studies were included for full-text reading. Five studies were included (one randomized single-blind study, two randomized double-blind split-mouth studies, and two randomized clinical trials) in the review. Four out of five studies that were included in this review demonstrated a positive impact of PBMT on reducing pain, especially during the post-operative period compared to other non-surgical treatment protocols. Photo-biomodulation therapy demonstrated an overall positive impact on reducing postoperative complications like edema and trismus.
ABSTRACT
Florid cemento-osseous dysplasia (COD) represents a rare group of benign fibro-osseous disorders, while osteogenic sarcoma (OS) on the other hand, is a malignant tumour of ominous prognosis. The malignant transformation of a benign fibro-osseous lesion of the jaw is quite uncommon and has few reported cases. The clinico-radiological findings and histopathological analysis of a lesion present in all four quadrants of the jaw of a patient who reported at the outpatient department of a regional dental college is presented here. The lesion underwent sarcomatous transformation over two months and the findings were confirmed by histopathological evaluation. Although florid cemento-osseous dysplasia is a benign lesion of the jaw with a very low propensity for malignant transformation, it should be closely monitored in patients with tumour predisposition syndromes. Further research and molecular studies are required for better understanding of inadvertent changes.
ABSTRACT
Background & objectives: Recent data suggest that insulin resistance can predict cardiovascular disease independently of the other risk factors, such as hypertension, visceral obesity or dyslipidaemia. However, the majority of available methods to evaluate insulin resistance are complicated to operate, expensive, and time consuming. This study was undertaken to assess whether serum lipoprotein ratios could predict insulin resistance in non-diabetic acute coronary syndrome (ACS) patients. Methods: Ninety non-diabetic patients with impaired fasting glucose admitted with a diagnosis of ACS were included in the study. At the time of admission fasting glucose and insulin concentrations were measured. The homeostatic model assessment-insulin resistance (HOMA-IR) was used for insulin resistance. The fasting serum total cholesterol (TC), triglycerides (TG) and high density lipoprotein cholesterol (HDL-C) levels were checked, and then TC/HDL-C and TG/HDL-C ratios were calculated. The areas under the curves (AUC) of the receiver operating characteristic (ROC) curves were used to compare the power of these serum lipoprotein ratios as markers. Results: Lipoprotein ratios were significantly higher in patients with HOMA-IR index > 2.5 as compared to patients with index <2.5 (P < 0.05). Both TG/HDL-C and TC/HDL-C ratios were significantly correlated with HOMA-IR (P<0.05). The area under the ROC curve of the TG/HDL-C and TC/HDL-C ratio for predicting insulin resistance was 0.80 (95% CI, 0.67 to 0.93), 0.78 (95% CI, 0.65 to 0.91), respectively. Interpretation & conclusions: The findings of this study demonstrate that serum lipoprotein ratios can provide a simple means of identifying insulin resistance and can be used as markers of insulin resistance and cardiovascular diseases risk in adult non-diabetic patients.

Human monocytic ehrlichiosis is a tick-borne infectious disease transmitted by several tick species, especially Amblyomma spp caused by Ehrlichia chaffeensis. E. chaffeensis is an obligatory intracellular, tick-transmitted bacterium that is maintained in nature in a cycle involving at least one and perhaps several vertebrate reservoir hosts. Two additional Ehrlichia spp, Anaplasma (formerly Ehrlichia) phagocytophila (the agent of human granulocytic ehrlichiosis [HGE]) and E. ewingii (a cause of granulocytic ehrlichiosis in dogs) act as human pathogens. Human E. chaffeensis infections have generally been reported in North America, Asia and Europe, but recently human cases have been reported in Brazil only. Human monocytic ehrlichiosis is diagnosed by demonstration of a four-fold or greater change in antibody titer to E. chaffeensis antigen by IFA in paired serum samples, or a positive PCR assay and confirmation of E. chaffeensis DNA, or identification of morulae in leukocytes and a positive IFA titer to E. chaffeensis antigen, or immunostaining of E. chaffeensis antigen in a biopsy or autopsy sample, or culture of E. chaffeensis from a clinical specimen.

OBJECTIVES: To evaluate the role of thyroid ultrasound in children with autoimmune thyroiditis diagnosed either on cytopathology or by the presence of thyroid peroxidase antibodies. DESIGN AND SETTINGS: Children presenting for the first time to the Thyroid Clinic at the Institute of Nuclear Medicine and Allied Sciences for the complaint of goiter over a two year period (January 2005-December 2006) were studied. SUBJECTS: 695 school children (244 boys and 451 girls) aged 5-18 year were studied. METHODS: Children were subjected to thyroid ultrasound, cytopathology, thyroid peroxidase antibody and thyroid function tests. RESULTS: Overall, 16% of goitrous children had hypoechogenicity on ultrasound, 15.2% had cytopathological evidence of thyroiditis, 10.6% had positive thyroid peroxidase antibodies and 25.2% had abnormal thyroid function tests. Subjects with hypoechogenicity had higher percentage of thyroiditis on cytopathology (41.4% vs. 10.3%; P<0.01), thyroid peroxidase antibody positivity (30.6% vs. 6.8%; P<0.01) and thyroid dysfunction (46.8% vs. 21.2%; P<0.01) than those with normal echogenicity. CONCLUSION: Thyroid USG has a useful, though limited, role in excluding thyroid disease in children. The sensitivity of echogenicity for the diagnosis of autoimmune thyroiditis in children is less than that reported in adults.

BACKGROUND: Ultrasound assessment of thyroid volume is considered a more objective method than clinical palpation for the diagnosis of goitre. We used ultrasonography to establish normal reference cut-off points of thyroid volume in schoolchildren of different socioecomonic groups in India and compared the results with international norms. METHODS: In a cross-sectional study, we clinically examined 27,250 children from the lower and higher socioeconomic strata (SES) from all over India to determine their goitre staging. A single sonologist, using ultrasonography, assessed the thyroid volume in a subset of 15,986 children (8463 from the lower and 7523 from the higher SES). Students were recruited from at least one school each representing the higher and the lower SES, from cities located in 5 zones of India. Children with known thyroid disorders were excluded from the study. RESULTS: Clinical evaluation revealed a mean goitre prevalence of 19.9% (23.2% in girls; 16.5% in boys; 17.1% in the higher SES; 23.5% in the lower SES). The thyroid volume as assessed by ultrasonography was significantly higher in children from the lower SES (mean 5.65 ml, SE 0.02) compared with those from the higher SES (mean 5.02 ml, SE 0.02) after adjusting for the imbalance in body surface area (p < 0.001). Using international norms (WHO 2004), the prevalence of goitre in various body surface area categories among children who had no goitre on clinical examination ranged from 48.2% to 75.1% for boys and 23.2% to 67.4% for girls. CONCLUSION: The striking discrepancy in the prevalence of goitre assessed by using clinical examination and ultrasound techniques suggests that the norms recommended by WHO based on ultrasound techniques are not appropriate for India.

The study reports on the genesis of domestic sewage in a predominantly residential university campus area ofDhanbad, Jharkhand. The domestic sewage has been collected from three different locations of the campus area and their physicochemical characteristics have been studied. These studies reveal that the extent of mineral pick-up is different for different parameter. It has been found out in the present study that in the domestic sewage, the chloride pick-up is 71%, nitrate pick-up is 97%, total hardness pick-up is 20 %, iron pick-up is 98% and zinc pick-up is 98%. The rate constants have been found out by using standard methods and have been compared with those mentioned in the standard literatures and previous works.

Hypertension is a common clinical problem with great implications for public health. It is a silent killer and often remains asymptomatic. So regular BP check-up is a must. Complications of untreated hypertension include ventricular hypertrophy, heart failure and accelerated atherosclerosis, cerebrovascular disease and stroke, renal failure and retinopathy. Primary care physicians have immense duty to perform in this regard because they are the first to encounter them in various stages of the disease. Hypertension can present per se or in emergencies (as in crisis) or in disguise of a complication (like anaemia and renal failure). Control of hypertension and delaying the development of complications should be their first goal. Lastly, some hypertensives with complications may require referral to advanced centres.

Isolated circulating immune complexes (CICs) from sera of patients with amoebiasis were characterized to determine Entamoeba histolytica antigens that participate in the disease process. In total, 116 serum samples were collected before starting anti-amoebic therapy, and their CICs were isolated by differential polyethylene glycol precipitation. The presence of amoeba-specific antigens in CICs was detected by antigen capture enzyme-linked immunosorbent assay (ELISA) and by immunoblot assay. Antigen capture ELISA showed significantly higher optical density (p < 0.001) in all patients with amoebiasis than in the normal healthy controls and patients of non-amoebic hepatic disorder. Immunoblot assay detected amoeba-specific CICs in all 18 patients (100%) with confirmed amoebic liver abscess, 28 (80%) of 35 patients with clinically-suspected amoebic liver abscess, and 18 (78.26%) of 23 patients with amoebic colitis. No patients with non-amoebic hepatic disorders and healthy control subjects had any detectable level of amoebic antigens in CICs. Immunoblot assay revealed E. histolytica antigens of relative molecular masses of 35, 56, 70, and 90 kDa present in CICs of 64 of 76 patients with amoebiasis. The 35-kDa polypeptide was observed in 52 patients (81.25%). The results of the study suggest that the 35-kDa polypeptide antigen can be a diagnostic marker in active amoebiasis.

Upper gastrointestinal bleeding is a potentially fatal condition at times due to loss of large volumes of blood. Common sources of upper gastrointestinal bleeding in children include mucosal lesions and variceal hemorrhage (most commonly extra hepatic portal venous obstruction) and, in intensive care settings infections and drugs are other etiological factors associated with bleeding. Massive upper GI bleeding is life threatening and requires immediate resuscitation measures in the form of protection of the airways, oxygen administration, immediate volume replacement with ringer lactate or normal saline, transfusion of whole blood or packed cells and also monitoring the adequacy of volume replacement by central venous lines and urine output. Upper GI endoscopy is an effective initial diagnostic modality to localize the site and cause of bleeding in almost 85-90% of patients. Antacids supplemented by H2- receptor antagonists, proton pump inhibitors and sucralfate are the mainstay in the treatment of bleeding from mucosal lesion. For variceal bleeds, emergency endoscopy is the treatment of choice after initial haemodynamic stabilization of patient. If facilities for endoscopic sclerotherapy (EST) are not available, pharmacotherapy which decreases the portal pressure is almost equally effective and should be resorted to. Shunt surgery is reserved for patients who do not respond to the above therapy. Beta blockers combined with sclerotherapy have been shown to be the most effective therapy in significantly reducing the risk of recurrent rebleeding from varices as well as the death rates, as compared to any other modality of treatment. Based on studies among adult patients, presence of shock, co-morbidities, underlying diagnosis, presence of stigmata of recent hemorrhage on endoscopy and rebleeding are independent risk factors for mortality due to upper GI bleeding. Rebleeding is more likely to occur if the patient has hematemesis, liver disease, coagulopathy, hypotension and or anemia. There is a great need for conducting therapeutic trials as well as identifying predictors of outcome of upper GI bleeding in children to develop evidence based management protocols.

BACKGROUND & OBJECTIVE: Pulmonary responses of children chronically exposed to ambient air pollution in Calcutta have been investigated. METHODS: A total number of 153 children from Calcutta and 116 from rural West Bengal in the age group of 6-17 yr were included in this study. Respiratory symptom complex, sputum cytology and micronucleus (MN) count of buccal epithelial cells were evaluated. Blood smears were examined for WBC differential count and RBC morphology. RESULTS: Marked rise in respiratory symptoms (43% in urban vs 14% in rural) and sputum alveolar macrophage (AM) number was observed in urban children compared to their rural counterparts (14.2 +/- 1.4 AM/hpf vs 6.7 +/- 1.4 AM/hpf, mean +/- SE, P < 0.001). The urban group also demonstrated increased numbers of neutrophils, eosinophils and iron-laden AM in their sputum. Besides, buccal epithelial cells of urban children exhibited higher MN frequency than their rural counterparts (0.22 vs 0.17%, P < 0.05). While sputum neutrophilia and eosinophilia suggest inflammatory and allergic lung reactions, elevated MN count is indicative of greater genotoxic effect on the exposed tissues of urban children. Hypochromic red cells in peripheral blood smear was a common finding in both urban and rural groups, but eosinophils and monocytes were present in elevated frequencies in the rural children. INTERPRETATION & CONCLUSION: The study demonstrated that children inhaling grossly polluted air of Calcutta suffer from adverse lung reactions and genetic abnormality in the exposed tissues.
