ABSTRACT

Background: Cutaneous mucormycosis has shown a significant upsurge during the COVID-19 pandemic. Due to the rapid progression and high mortality of cutaneous mucormycosis in this context, it is important to identify it early. However, very few studies report detailed clinical descriptions of cutaneous mucormycosis in COVID-19 patients. Objectives: To describe mucocutaneous lesions of COVID-19-associated mucormycosis based on clinical morphology and attempt to correlate them with radiological changes. Methods: A retrospective cross-sectional study was conducted at a tertiary care centre from 1st April to 31st July 2021. Eligibility criteria included hospitalised adult patients of COVID-19-associated mucormycosis with mucocutaneous lesions. Results: All subjects were recently recovering COVID-19 patients diagnosed with cutaneous mucormycosis. One of fifty-three (2%) patients had primary cutaneous mucormycosis, and all of the rest had secondary cutaneous mucormycosis. Secondary cutaneous mucormycosis lesions presented as cutaneous-abscess in 25/52 (48%), nodulo-pustular lesions in 1/52 (2%), necrotic eschar in 1/52 (2%) and ulcero-necrotic in 1/52 (2%). Mucosal lesions were of three broad sub-types: ulcero-necrotic in 1/52 (2%), pustular in 2/52 (4%) and plaques in 1/52 (2%). Twenty out of fifty-two patients (38%) presented with simultaneous mucosal and cutaneous lesions belonging to the above categories. Magnetic resonance imaging of the face showed variable features of cutaneous and subcutaneous tissue involvement, viz. peripherally enhancing collection in the abscess group, “dot in circle sign” and heterogeneous contrast enhancement in the nodulo-pustular group; and fat stranding with infiltration of subcutaneous tissue in cases with necrotic eschar and ulcero-necrotic lesions. Limitations: The morphological variety of cutaneous mucormycosis patients in a single-centre study like ours might not be very precise. Thus, there is a need to conduct multi-centric prospective studies with larger sample sizes in the future to substantiate our morphological and radiological findings. Conclusions: COVID-19-associated mucormycosis patients in our study presented with a few specific types of mucocutaneous manifestations, with distinct magnetic resonance imaging findings. If corroborated by larger studies, these observations would be helpful in the early diagnosis of this serious illness.

ABSTRACT

Purpose: To evaluate the effectiveness of repeat deep anterior lamellar keratoplasty (DALK) in patients of previous failed DALK. Methods: A retrospective analysis of records of seven patients who had undergone repeat DALK following the failure of the primary DALK was done. The indications for repeat surgery, time elapsed since the first surgery, and pre? & postoperative best?corrected visual acuity (BCVA) were noted for all the patients. Results: The follow?up period ranged between one? to four?year post repeat DALK. The indication of primary DALK was keratoconus with vernal keratoconjunctivitis (VKC) (n = 3), corneal amyloidosis (n = 2), Salzman nodular keratopathy (n = 1), and healed keratitis (n = 1). The need for repeat surgery arose when the BSCVA dropped to less than 20/200. The time interval elapsed since the first surgery ranged from two months to four years. Postoperatively, the BSCVA improved from 20/120 to 20/30 at the end of one?year post repeat DALK in all except one patient. All regrafts were clear at the most recent examination, performed after a mean period of 18 months after the secondary graft. No complication was encountered during the resurgery. The dissection of the host bed was easier in the second surgery owing to weaker adhesions. Conclusion: The prognosis for repeat DALK for failed DALK is excellent, and the outcomes of secondary grafts were comparable to those of primary DALK grafts. Re DALK offers the advantage of an easier dissection and lower chances of graft rejection compared to penetrating keratoplasty.

ABSTRACT

Purpose: Glaucoma is the second leading cause of blindness worldwide, affecting more than 64 million people aged 40–80. The best way to manage primary open?angle glaucoma (POAG) is by lowering the intraocular pressure (IOP). Netarsudil is a Rho kinase inhibitor, the only class of antiglaucoma medications that reorganizes the extracellular matrix to improve the aqueous outflow through the trabecular pathway. Methods: An open?label, real?world, multicentric, observation?based 3?month study was performed for assessing the safety and ocular hypotensive efficacy of netarsudil ophthalmic solution (0.02% w/v) in patients with elevated IOP. Patients were given netarsudil ophthalmic solution (0.02% w/v) as a first?line therapy. Diurnal IOP measurements, best?corrected visual acuity, and adverse event assessments were recorded at each of the five visits (Day?1: screening day and first dosing day; subsequent observations were taken at 2 weeks, 4 weeks, 6 weeks, and 3 months). Results: Four hundred and sixty?nine patients from 39 centers throughout India completed the study. The mean IOP at baseline of the affected eyes was 24.84 ± 6.39 mmHg (mean ± standard deviation). After the first dose, the IOP was measured after 2, 4, and 6 weeks, with the final measurement taken at 3 months. The percentage reduction in IOP in glaucoma patients after 3 months of once?daily netarsudil 0.02% w/v solution use was 33.34%. The adverse effects experienced by patients were not severe in the majority of cases. Some adverse effects observed were redness, irritation, itching, and others, but only a small number of patients experienced severe reactions, as reported in a decreasing order: redness > irritation > watering > itching > stinging > blurring. Conclusion: We found that netarsudil 0.02% w/v solution monotherapy when used as the first?line treatment in primary open?angle glaucoma and ocular hypertension was both safe and effective.

ABSTRACT

Background & objectives: The diagnosis of scrub typhus (ST) is usually done using enzyme-linked immunosorbent assay (ELISA) due to its ease of performance and reading objectivity. The cut-off value for ELISA needs to be calculated for each geographical location as it depends on zonal endemicity of the disease. This study was, therefore, undertaken to calculate the pan-India cut-off for anti-Orientia tsutsugamushi (OT) immunoglobulin M (IgM) by ELISA. Methods: Samples from cases (cases of ST) and controls (voluntary, consenting, healthy adults) were collected by a network of 29 laboratories across India and tested for anti-OT IgM by immunofluorescence assay (IFA), the considered gold standard test. These samples were retested by ELISA for anti-OT IgM and their optical densities (ODs) were used for cut-off estimation by receiver operating characteristic (ROC) curve. Results: Anti-OT IgM ELISA ODs from 273 controls and 136 cases were used for the cut-off estimation. The ODs of the anti-OT IgM ELISA on healthy individuals and those of confirmed ST cases ranged from 0.1 to 0.75 and 0.5 to 4.718, respectively. ROC curve-based cut-off for ELISA was calculated as 0.554 at a sensitivity of 95.2 per cent and specificity of 95.1 per cent. A value of >1 was noted to have a specificity of 100 per cent in diagnosing ST. Interpretation & conclusions: The cut-off calculated for India was similar to the previous cut-off that was used until now.

ABSTRACT

Purpose: To determine the morphology of pediatric cataracts and assess the status of the anterior and posterior capsules preoperatively on swept?source anterior segment optical coherence tomography (ASOCT) and compare the findings to those of intraoperative examination. Secondly, we aimed to obtain biometric measurements on ASOCT and compare them to those obtained on A?scan/optical methods. Methods: This was a prospective and observational study carried out at a tertiary care referral institute. ASOCT scans for anterior segment were obtained preoperatively for all patients, aged <8 years, scheduled for paediatric cataract surgery. The morphology of the lens and capsule and biometry were performed on ASOCT and the same were assessed intraoperatively. The main outcome measures were comparison of ASOCT findings to intraoperative findings. Results: The study included 33 eyes of 29 patients (range 3 months–8 years). The morphological characterization of cataract on ASOCT was accurate in 31/33 (94%) cases. ASOCT accurately identified fibrosis and rupture of the anterior and posterior capsules in 32/33 (97%) cases each. In 30% of eyes, ASOCT gave additional information preoperatively compared to the slit lamp. Intraclass correlation coefficient (ICC) calculation revealed a good agreement between the keratometry values obtained on ASOCT and those obtained preoperatively with a handheld/optical keratometer (ICC = 0.86, P = 0.001). Conclusion: ASOCT is a valuable tool that could provide complete preoperative information of the lens and capsule in pediatric cataract cases. In children as young as 3 months of age, intraoperative risks and surprises could be diminished. The keratometric readings are highly dependent on patient cooperation but show good agreement with the handheld/optical keratometer readings.

ABSTRACT

Purpose: To evaluate the outcome of glaucoma drainage device (GDD) insertion of tube through ciliary sulcus (CS) versus anterior chamber (AC) placement in the North Indian population Methods: This retrospective comparative case series included 43 patients in CS group and 24 in AC group, who underwent GDD implantation, from March 2014 to February 2020. The main outcome measures were intraocular pressure (IOP), number of anti?glaucoma medications, best corrected visual acuity (BCVA), and complications. Results: Sixty?seven eyes of 66 patients were included in study with mean follow?up of 25.04 months (range, 12–69 months) in the CS group and 17.4 months (range, 13–28 months) in the AC group. Preoperatively the two groups were similar except for postpenetrating keratoplasty glaucoma (PPKG) and pseudophakic patients, which were higher in the CS group (P < 0.05). Both groups showed statistically insignificant difference in postoperative IOP and BCVA at last follow?up (P = 0.173, P = 0.495, respectively). Postoperative complications were similar, except for corneal decompensation which was significantly higher in the AC group (P = 0.042). Conclusion: Our findings suggest that there was no statistically significant difference in mean IOP between the CS and AC groups at the last follow?up. CS placement of tube of GDD appears to be effective and safe technique. However, CS placement of tube resulted in lesser corneal decompensation and thus should be preferred in pseudophakic/aphakic patients, especially PPKG.

ABSTRACT

Purpose: India has the largest population of youth in the world, thereby making them important contributors to the “India of Tomorrow”. Over 80% of knowledge gained is by the visual sense, thereby making school screening programs a necessity in our country. Data from the pre?COVID era, that is, 2017–18 was collected from close to 19,000 children in Gurugram, Haryana, a tier two city in National Capital Region, India. A similar prospective observational study is planned post COVID?19 (2022–23) for further analysis to depict the impact of COVID?19 in these areas. Methods: The program They See, They Learn was set at government schools in the area of operations (district of Gurgaon, Haryana), where the children and their families were unable to afford eye care services. All children who were screened underwent a comprehensive eye examination at the school premises itself. Results: A total of 18,939 students were screened over a period of 18 months, covering a total of 39 schools in the Gurugram belt, in the first phase of the program. Eleven point eight percent (n = 2254) of all school students had some form of refractive error. Girl students were found to have a higher refractive error rate (13.3%) compared to boy students (10.1%) across the schools screened. Myopia was the most common type of refractive error. Conclusion: School students require perfect vision or else they can be discouraged and may become a major burden to the economy of any developing nation. A school screening program aiming at populations that cannot afford such basic needs like spectacles is a must in all zones of the country

ABSTRACT

Background : 20-30% of the Indian population suffers from at least one allergic disease that can have an adverse impact on the quality of life of the patients. Aim : To develop expert opinion-related guidance for the diagnosis and management of allergic disorders. Methodology : An advisory board meeting (hybrid mode) was conducted with 11panel members of the Indian Medical Association (IMA). The panel members discussed issues related to the management of allergic disorders based on the Delphi method. Result : Spirometry is helpful in selected patients of allergic rhinitis where the coexistence of asthma is suspected. In patients with urticaria second-generation antihistamines are preferred for both adults and children due to their low side effects, less drug-drug interaction, anticholinergic effects, longer duration of action, and higher safety. Diagnosis of allergic contact dermatitis can be made based on occupational and exposure history. In atopic dermatitis, patient education about lifestyle changes can prevent flare-ups. In patients with asthma, patients must be educated about the use of the peak flow meter. The diagnosis of food allergy can be made by correlating the food intake timing withthe patient history and the results of allergy testing. Allergic drug reactions can be treated with oral antihistaminic drugs, emollients, and if needed topical corticosteroids. Conclusion : The diagnosis of allergic disorders requires the clinician to consider the clinical presentation, patient history, presence of triggers, and comorbid conditions. Patient education and the new generation of antihistaminic drugs can improve the quality of life of patients with allergic disorders

ABSTRACT

Purpose: To assess the perception of college?going girls toward corneal donation in Northern India. Methods: An online survey with a pre?structured, pre?validated questionnaire was conducted on 1721 college?going girls in Northern India. The knowledge and attitude scores were regressed, and latent class analysis was carried out. Results: The average of scores for all participants was computed individually for the knowledge questions and the attitude questions, and based on this score, total participants were divided into two groups: Better corneal donation behaviors (BCDB) and poor corneal donation behaviors. The binomial logistic regression model of knowledge domain for predicting BCDB, age of the participant, their awareness about corneal donation, and willingness to discuss eye donation among family members were found significant. Similarly, for the attitude domain, awareness about corneal donation, knowledge about hours within which ideal eye donation needs to be undertaken, and knowledge about eye donation during coronavirus disease 2019 (COVID?19) pandemic were found to be significant. Latent class analysis identified one subset of participants having poorer knowledge and attitude scores and that they were more from a rural background, were having more than first order as birth order, were belonging to SC/ST classes, had illiterate or secondary education of father and mother, and were living in rented houses. Conclusion: The findings of the study significantly contribute to devising a mechanism to improve knowledge and influencing the attitude about eye donation among the youth, especially young women, who can act as counselors and motivators for the masses as well as their own families, in the generations to come.

ABSTRACT

The neglected tropical disease mycetoma can become extremely devastating, and can be caused both by fungi and bacteria; these are popularly known as eumycetoma and actinomycetoma respectively. The classical triad of the disease is subcutaneous swelling, multiple discharging sinuses and the presence of macroscopic granules. The present study aims to highlight the existing diagnostic modalities and the need to incorporate newer and more advanced laboratory techniques like pan fungal/pan bacterial 16S rRNA gene polymerase chain reaction (PCR) and sequencing, Matrix-assisted laser desorption/ionization-time of flight mass spectrometry (MALDI-TOF MS), rolling circle amplification (RCA), loop-mediated isothermal amplification (LAMP) and recombinase polymerase amplification (RPA). It is important for the medical team to be aware of the various diagnostic options (both existing and future), so that diagnosis of such a debilitating disease is never missed, both by clinicians and microbiologists/pathologists. The newer diagnostic methods discussed in this article will help in rapid, accurate diagnosis thus facilitating early treatment initiation, and decreasing the overall morbidity of the disease. In the Indian context, newer technologies need to be made available more widely. Making clinicians aware and promoting research and development in mycetoma diagnostics is the need of the hour.

ABSTRACT

Purpose: To compare the quality of life (QoL) in patients with glaucoma on medical therapy and after trabeculectomy and glaucoma drainage device (GDD) using vision, glaucoma, and surgery?specific questionnaires. Methods: This cross?sectional study enrolled 30 patients of moderate to severe glaucoma, each in medical, trabeculectomy, and GDD groups. National Eye Institute Visual Function Questionnaire 25 (NEIVFQ?25), Glaucoma Quality of Life (GQL?15), and Surgery Specific Questionnaire (SSQ) were administered, and cumulative scores were compared. Results: The mean age of the participants was 58.95 ± 13.6 years with a male preponderance (73.3%, n = 66). The mean scores (SD) in the medical, trabeculectomy, and GDD groups using NEIVFQ?25 were 68.97 (6.98), 72.83 (7.81), and 75.20 (8.77), respectively, those using GQL?15 were 20.63 (6.00), 26.23 (9.12), and 28.43 (7.74), respectively, and for the SSQ, they were 74.33 (8.75) and 72.10 (5.92) in trabeculectomy and GDD groups, respectively. NEIVFQ?25 showed a better QoL in the GDD group compared to the medical group, whereas GQL?15 showed a better QoL in the medical group and comparable QoL in trabeculectomy and GDD. Both these QoL scores correlated to the LogMAR visual acuity. SSQ scores did not show a significant difference in the QoL across both surgical groups. Conclusion: NEIVFQ?25 questionnaire scores provided a holistic measure of QoL. GQL?15 assessed the activity limitation and visual disability of the patients but did not take into account the general health and psychological factors influencing the QoL. We did not find a significant difference between trabeculectomy and GDD using the SSQ. For QoL assessment in medically or surgically treated glaucoma, vision?specific and disease?specific questionnaires should always be used in conjunction

ABSTRACT

Introduction: Dengue and Chikungunya (CHIK) infections appear to be increasing in all parts of India. Aedes aegypti mosquitoes are common vectors for dengue virus (DENV) and CHIK virus (CHIKV - Chikungunya Virus). In areas where both viruses co circulate, they can be transmitted together. Aim: The present study was undertaken to study the prevalence of dengue–CHIK co infection and compare with monoinfection. Methods: IgM antibody capture ELISA (Enzyme linked immunosorbent assay) for dengue IgM and CHIK IgM and ELISA for dengue non structural protein 1 antigen was performed on serum samples obtained from suspected patients. Results: Out of total 1071 samples from suspected patients for dengue & chikungunya infection, 212 (19.7%) samples were positive for DENV while CHIK IgM antibodies were positive in 145 (13.53%) patients. Total 44 sera were positive (4.10%) for co-infection of dengue and CHIK. Conclusion: Increase in the number of Dengue and Chikungunya infections and their cocirculation is an important public health concern which warrants the implementation of strict control measures

ABSTRACT

Background: The COVID-19 has taken the world by storm. It primarily affects the lungs causing respiratory distress and leading to ARDS. Aim: The aim of this study is to evaluate the coagulation dysfunction in patients which predisposes the patients to venous and arterial thromboembolism due to excessive inflammation, hypoxia, immobilisation and diffuse intravascular coagulation (DIC). Material & Methods: We assessed 2281 COVID RT PCR positive patients who were admitted with moderate to severe disease in wards and ICU respectively. The coagulation profile was done for each of these patients and the tests included Prothrombin time (PT), Activated Partial Thromboplastin Time (APTT) and D-Dimer. The PT and APTT were estimated on ACL elite pro (Fully automated coagulation analyser) which is based on nephelometry. D- Dimer was measured using ACL elite pro and latex agglutination (semi quantitative method). Results: Out of 2281 COVID RT PCR positive patients 1655 (72.5%) were males and 626 (27.5%) were females. It was observed that percentage of patients admitted in ICU had increased D dimer values and it was statistically significant. Our study showed that larger number of patients admitted in ICU had PT value more than 12.5 seconds and APTT more than 35.5 seconds, however it was not statistically significant. Our study also demonstrated that patients having higher D dimer required longer hospitalization with significant p value. Conclusion: We concluded that assessment of coagulation profile is necessary for patients infected with this virus so as to prevent any thrombotic complications and therefore preventing morbidity and mortality.

ABSTRACT

Abstract Background and objectives Several anthropometric measurements have been suggested to identify a potentially difficult airway. We studied thyromental height (TMH) as a predictor of difficult laryngoscopy and difficult intubation. We also compared TMH, ratio of height to thyromental distance (RHTMD), and thyromental distance (TMD) as predictors of difficult airway. Methods This cross-sectional observational study was conducted in 300 adult surgical patients requiring tracheal intubation. Preoperatively airway characteristics were assessed. Standard anesthesia was administered. Degree of difficulty with mask ventilation, laryngoscopic view, duration of laryngoscopy, and difficulty in tracheal intubation (intubation difficulty scale score) were noted. Multivariate logistics regression analysis was performed to identify independent predictors for difficult laryngoscopy. Results Laryngoscopy was difficult in 46 of 300 (15.3%) patients; all 46 patients had Cormack-Lehane grade 3 view. Duration of laryngoscopy was 27 ± 11 s in patients with difficult laryngoscopy and 12.7 ± 3.9 s in easy laryngoscopy; p= 0.001. Multivariate analysis identified that TMH, presence of short neck, and history of snoring were independently associated with difficult laryngoscopy. Incidence of difficult intubation was 17.0%. A shorter TMH was associated with higher IDS scores; r = -0.16, p= 0.001. TMH and duration of laryngoscopy were found to be negatively correlated; a shorter TMH was associated with a longer duration of laryngoscopy; r = -0.13, p= 0.03. The cut-off threshold value for TMH in our study is 4.4 cm with a sensitivity of 66% and a specificity of 54%. Conclusion Thyromental height predicts difficult laryngoscopy and difficult intubation. TMD and RHTMD did not prove to be useful as predictors of difficult airway.

ABSTRACT

Background & objectives: Studies assessing the spatial and temporal association of ambient air pollution with emergency room visits of patients having acute respiratory symptoms in Delhi are lacking. Therefore, the present study explored the relationship between spatio-temporal variation of particulate matter (PM)2.5 concentrations and air quality index (AQI) with emergency room (ER) visits of patients having acute respiratory symptoms in Delhi using the geographic information system (GIS) approach. Methods: The daily number of ER visits of patients having acute respiratory symptoms (less than or equal to two weeks) was recorded from the ER of four hospitals of Delhi from March 2018 to February 2019. Daily outdoor PM2.5 concentrations and air quality index (AQI) were obtained from the Delhi Pollution Control Committee. Spatial distribution of patients with acute respiratory symptoms visiting ER, PM2.5 concentrations and AQI were mapped for three seasons of Delhi using ArcGIS software. Results: Of the 70,594 patients screened from ER, 18,063 eligible patients were enrolled in the study. Winter days had poor AQI compared to moderate and satisfactory AQI during summer and monsoon days, respectively. None of the days reported good AQI (<50). During winters, an increase in acute respiratory ER visits of patients was associated with higher PM2.5 concentrations in the highly polluted northwest region of Delhi. In contrast, a lower number of acute respiratory ER visits of patients were seen from the ‘moderately polluted’ south-west region of Delhi with relatively lower PM2.5 concentrations. Interpretation & conclusions: Acute respiratory ER visits of patients were related to regional PM2.5 concentrations and AQI that differed during the three seasons of Delhi. The present study providessupport for identifying the hotspots and implementation of focused, intensive decentralized strategies to control ambient air pollution in worst-affected areas, in addition to the general city-wise strategies.

ABSTRACT

Purpose: To ascertain normative database of contrast sensitivity (CS) using Spaeth/Richman CS test (SPARCS) in the Indian population. Methods: This cross?sectional study enrolled 200 healthy individuals, and CS was tested in both eyes of each participant using SPARCS. A detailed ocular examination was done before enrollment to rule out pathologies that may affect CS. A practice test was performed in the right eye (OD), followed by uniocular testing in each eye and a final binocular test. Results: Data of 400 eyes of 200 subjects who fulfilled the inclusion criteria was evaluated. The average age of subjects was 46.57 ± 16.77 years (range 21–79 years), with a slight female preponderance (53%, n = 106). A statistically significant decline in average SPARCS scores was noted with increasing age (P < 0.05), ranging from 86.68 (20–29 years age group) to 67.44 (70–79 years age group). Higher scores were noted in binocular testing than uniocular testing (Interclass correlation coefficient [ICC] = 0.83; P < 0.001). Females achieved statistically significant higher total scores in uniocular SPARCS testing (both OD and OS), but there was no significant difference noted between the two genders in binocular testing. Correlation between practice and main tests was statistically Significant with an interclass correlation coefficient of 0.54 (P < 0.001). Conclusion: Normative database for SPARCS was established for Indian eyes, with a decreasing trend noted in peripheral as well as central CS scores with increasing age.

ABSTRACT

Background: Dengue fever and dengue haemorrhagic fever currently rank highly among the newly emerging infectious diseases and are the most important arboviral disease worldwide. Dengue virus can be distinguished by both serological and molecular methods. This study was aimed at analysing the prevalence and laboratory dynamics of the four dengue serotypes in tertiary care patients attending GMERS Medical College Gandhinagar. Material & methods: This study was an observational retrospective study. A total 105 samples were tested for Dengue serotyping by RT-PCR. Results: Among positive patients Dengue virus serotype-2 was the most common serotype 94 (89%) followed by DENV3 7(6%) and DENV4 2(2%). Co-infection with DENV 2/4 was 2(2%). A higher prevalence of dengue haemorrhagic fever was noted in serotype 2 compared to serotypes 3, 4, and coinfection. Thrombocytopenia was present in all serotypes of infection. There was a significant difference in the disturbance of liver function in DENV2, as compared to others serotype. Dengue serotype 2 was very common in rural areas, while dengue serotype 3 was seen in the urban Gandhinagar zone. Discussion: Dengue is the most extensively spread mosquito-borne disease. As per previous studies most common prevalent and severity of serotype wasDENV2, however in our study we were able to identify DENV3, DENV4 and confection with serotypes (DENV2 & DENV4).

ABSTRACT

Background: Cancer of unknown primary (CUP) origin is cancer in which malignant cancer cells are in the body but the site of cancer where it began is unknown. Detailed incidence and time trends of these cancers, specific to various regions in India is needed. This paper aims to summarize and report the incidence of other and unknown (O&U) cancers across India in 27 population-based cancer registries (PBCRs) and to study the trends among these cancers using joinpoint regression analysis. Methods: Data on the incidence of CUP were obtained from the published reports on 27 PBCRs of the National Cancer Registry Programme (NCRP) of the Indian Council of Medical Research (ICMR). A joinpoint regression model was used to analyze the long-term trends of incidence related to CUP based on published data from PBCRs between 1986 and 2014. Annual Percent Change (APC) in incidence rate was estimated for various registries. Results: The northeast region had the highest age-adjusted rate (AAR) for both men (1.76–29.7) and women (1.99–14.68). Age-specific rate (ASR) for both men (39.8–855.7) and women (48.2–470.4) was highest in the northeast region. There is an increase in the incidence rate for all six major registries over the past decade with an exception of women in the Delhi Cancer Registry. There is a decline in incidence rate by 0.14 during 1990–2012 in the female population of the Delhi registry. Conclusion: The increasing incidence trends of CUP is a matter of concern for the healthcare professionals and researchers. There is a need for research and advanced and improved diagnostic tools for the improvement of the status of O&U cancers.
