Utility of guided FNAC and cell block preparation from liver and gall bladder masses: Learning experience from a tertiary care center.

INTRODUCTION: Ultrasound- and CT-guided fine needle aspiration cytology (FNAC) increases the accessibility of intra-abdominal masses to the liver and gall bladder with the advantages of low cost and high diagnostic yield. Cell block technique has been known for further increasing the diagnostic accuracy. AIMS AND OBJECTIVES: We aimed to study the effectiveness of FNAC and the cell block method in cytological diagnosis of liver and gall bladder masses. We also followed a step-wise approach to increase the success rate. MATERIALS AND METHODS: A 2-year observational study was done from July 2020 to June 2022. Total 80 guided (CT and ultrasound) aspirations were done from space occupying/mass lesions in the liver [74 (92.5%)] and gall bladder [6 (7.5%)], out of which cell blocks by the plasma thrombin method were prepared in 12 cases (15%). The on-site radiological details were noted, and rapid on-site evaluation was done in 65 cases (81.25%). The prepared cytology slides were stained with Papanicolaou, H and E and May-Grunwald Giemsa (MGG) stain. The cytological diagnosis was noted, and the uses and limitations (if any) were observed in each case. A step-wise structured questionnaire format was developed to assist the reporting pathologist so as not to miss out on important diagnostic observations, if present. RESULTS: FNAC in 71 cases (88.7%) gave a conclusive diagnosis. The maximum number of cases were of adenocarcinoma [38 (51.3%)] from the liver followed by hepatocellular carcinoma in 10 cases (13.5%). In gall bladder masses, all 6 cases (100%) were positive for malignancy, out of which 4 cases (66.7%) could be characterized as adenocarcinoma. The cell block preparation was helpful in reaching the diagnosis as well as typing the malignancy in 10 cases (83.3%). The chief limitation observed on conventional cytology smears was inadequate cellularity, which caused inconclusive diagnosis in 9 cases (11.25%). The reporting questionnaire was helpful chiefly in terms of time-efficient reporting in 34 cases (42.5%), increasing the ease and confidence in 69 cases (86.25%) and the advantage of reproducibility of data in all cases (100%) according to the case-by-case evaluation by the reporting pathologists. CONCLUSION: Guided FNAC in conjunction with the cell block technique is extremely helpful in the evaluation of mass lesions of the liver and gall bladder for cytological diagnosis. A proper step-wise approach may be useful to reach a quick and effective diagnosis.

Association of pruritus with sleep in patients with psoriasis and chronic spontaneous urticaria: A cross-sectional study.

Background: Pruritus is a frequent complaint associated with various inflammatory dermatoses. Sleep is often disturbed because of pruritus but the impact of severity and diurnal pattern of pruritus has not been studied so far. Objectives: To estimate the prevalence of nocturnal itch (NI) and its association with itch severity, sleep disturbance and quality of life (QoL) compared with non-NI in chronic plaque psoriasis (CPP) and chronic spontaneous urticaria (CSU). Methods: We performed a cross-sectional study in patients aged ≥18 years with CPP or CSU for at least 6 weeks. A comprehensive in-house questionnaire designed for study formed the basis for categorizing patients into NI and non-NI. Validated instruments like visual analog scale, pruritus grading system, General Sleep Disturbance Scale, and Dermatology life quality index were used to assess itch severity, sleep, and QoL. Results: A total of 255 patients (CPP: 131; CSU: 124) were included in this study. Prevalence of NI was 43.5% (95% confidence interval: 34.9%-52.4%) in CPP and 29% (95% confidence interval: 21.2%-37.9%) in CSU. NI was strongly associated with higher pruritus grading system scores in CSU and CPP (regression coefficient = 1.5, P =0.004 and regression coefficient = 1.3, P =0.004, respectively), with impaired sleep (OR = 2.97, P = 0.025) in CPP and with itch-affected sleep in CSU. Itch severity was associated with impaired sleep; however, the association was modified by the presence of NI in CSU patients. Conclusion: Nocturnal itch is prevalent in chronic dermatoses and significant for sleep deficit and impaired QoL. Early screening and management of sleep disturbance among patients presenting with nocturnal itch should be routinely undertaken.

A Survey-Based Assessment of Awareness Regarding Parthenium hysterophorus in a Rural Population of North India.

Background Parthenium hysterophorus is a poisonous weed that has spread across the length and breadth of the Indian subcontinent. It is a common cause of dermatitis similar to other members of the family, such as ragweeds in the United States and chrysanthemums in Europe. Despite the common occurrence of the plant in the environment, the general population does not seem to be aware of its adverse effects. This cross-sectional study was conducted with the aim of assessing the awareness of P. hysterophorus in the local rural population. Methodology A questionnaire was designed by an expert panel consisting of three dermatologists after a bibliological survey and collection of published literature on P. hysterophorus. All adult patients >18 years of age approaching the outpatient department of dermatology at our tertiary health care center were included in a consecutive sampling manner. Patients with an unsound mind or those who refused to provide consent were excluded from the study. Results A total of 250 patients participated in the study, of whom 56.8% were male and 43.2% were female, with ages ranging from 18 to 80 years. The majority of the participants were farmers by occupation. Three-fourths of the participants (187, 74.8%) were able to identify the plant. Maximum participants (144, 57.6%) did not know about the ill effects of Parthenium, and 148 (59.2%) did not know about the method of controlling its spread. Conclusions The study was conducted among 250 respondents from a rural community in North India. Despite almost 75% of participants identifying the weed, more than half were neither aware of its ill effects nor knew about the methods of control. Furthermore, most participants were educated individuals yet remained ignorant. Emphasis needs to be made on awareness campaigns about the fast-spreading Parthenium and its ill effects.

Cerebral sparganosis masquerading brain neoplasm: A rare incidental case.

Sparganosis is a parasitic infection caused by plerocercoid larvae of the genera Spirometra. Cerebral sparganosis is one of its most serious complications wherein clinical and imaging findings may pose diagnostic challenge. Here we present a case of cerebral sparganosis which mimicked as brain tumour on clinicoradiological examination. The case is reported in view of its rarity in India and the need for awareness of the entity.

Delay of routine health care during the COVID-19 pandemic: A theoretical model of individuals' risk assessment and decision making.

Delaying routine health care has been prevalent during the COIVD-19 pandemic. Macro-level data from this period reveals that U.S. patients under-utilized routine health care services such as primary care visits, preventative tests, screenings, routine optometry care, dental appointments, and visits for chronic disease management. Yet, there is a gap in research on how and why patients understand risks associated with seeking or delaying routing health care during an infectious disease pandemic. Our research addresses this gap based on semi-structured interviews with 40 participants living in regions across the United States. By building upon Unger-Saldaña and Infante-Castañeda's model of delayed health care, we extend this model by articulating how health care delays happen during an infectious disease pandemic. Specifically, we show how perceptions of uncertainty and subjective risk assessments shape people's decisions to delay routine health care while they operate at two levels, internal and external to one's social bubble, interacting with each other.

Reticular Skin Rash as an Adverse Effect of 5-Azacitidine.

Azacitidine is a hypomethylating agent used for the treatment of patients with myelodysplastic syndrome (MDS). It has been approved by the Food and Drug Administration (FDA) and the European Medicines Agency for the treatment of MDS and is also indicated for the treatment of acute myeloid leukemia (AML). Injection site erythema, ecchymosis, and petechiae are some of the common cutaneous adverse reactions associated with azacitidine. This article describes a rare adverse cutaneous drug reaction with azacitidine in the form of a reticular generalized skin rash in a 28-year-old female with AML.

Perineal warty plaques: A case of verrucous porokeratosis.

Nonvenereal genital dermatoses form an important category of disorders, and verrucous porokeratosis is a rare and less recognized entity among the same. We present the case of a young adult male with warty growths over scrotum and buttocks for a year. Characteristic cornoid lamellae with typical differentiating features were seen in the histopathology, establishing the diagnosis. This case emphasizes the rare nonvenereal cause for a condition clinically mimicking condyloma acuminata.

Unusual non-trophic ulcerations in leprosy: A case series of 17 patients.

Non-neuropathic ulcers in leprosy patients are infrequently seen, and atypical presentations are prone to misdiagnosis. We evaluated diagnosed cases of leprosy between January 2017 and January 2020 for the presence of cutaneous ulceration, Ridley-Jopling subtype of leprosy, reactions and histologic features of these ulcerations. Treatment was given as WHO recommended multi-bacillary multi-drug therapy. We found 17/386 leprosy patients with non-neuropathic ulcers. We describe three causes - spontaneous cutaneous ulceration in lepromatous leprosy (one nodular and one diffuse), lepra reactions (five patients with type 1; nine with type 2, further categorised into ulcerated Sweet syndrome-like who also had pseudoepitheliomatous hyperplasia, pustulo-necrotic and necrotic erythema nodosum leprosum) and Lucio phenomenon (one patient). Our series draws attention towards the different faces of non-neuropathic ulcers in leprosy, including some atypical and novel presentations.

End of the road for terbinafine? Results of a pragmatic prospective cohort study of 500 patients.

BACKGROUND: There is a general impression among dermatologists in India that terbinafine has been losing its effectiveness in dermatophytoses over the past few years, but there are no recent data to support this. AIMS: To determine the effectiveness of terbinafine in tinea corporis, tinea cruris and tinea faciei with a pragmatic prospective cohort study. METHODS: A sample size of 361 patients was calculated taking a 5% margin of error and a 95% confidence level. Five hundred patients with tinea corporis, tinea cruris and tinea faciei confirmed by potassium hydroxide microscopy received oral terbinafine (5mg/kg/day) and topical terbinafine 1% applied twice daily for 4 weeks. Patients were evaluated at 2 and 4 weeks. Cure was defined as total clearance of lesions and negative microscopy. RESULTS: Patients who came for follow-up at 2 and 4 weeks numbered 357 and 362 respectively. Ten patients were cured at 2 weeks (cure rate 2%, 95% confidence interval 1.0-3.7%, intention-to-treat analysis) and 153 patients were cured at 4 weeks (cure rate 30.6%, 95% confidence interval 26.7-34.8%). LIMITATIONS: Culture and antifungal susceptibility testing were not performed since this was a pragmatic study. There was also no follow up after completion of treatment to check for relapses, but the poor response makes this less relevant. CONCLUSION: The effectiveness of terbinafine in dermatophytosis was abysmal in this study.

Ectopic hidradenoma papilliferum of eyelid: A rare entity with diagnostic challenge.

Hidradenoma papilliferum is a rare cutaneous adnexal tumour of middle aged females arising mainly in the apocrine sweat glands of perianal and genital region. Ectopic forms of this entity have been described with majority of them occurring on the head and neck region. We report a case of 16 years young male who presented with two small, well circumscribed, greyish-brown, firm, nodules on his left upper and lower eyelid. A clinical impression of basal cell carcinoma was assumed but on histopathological examination it was diagnosed as hidradenoma papilliferum of eyelid. Immunohistochemistry was performed to support the diagnosis due to its unusual clinical presentation. To the best of our knowledge, only six cases in the upper eyelid and one case in the lower eyelid have been reported in the English literature. This is the first case report of hidradenoma papilliferum involving both upper and lower left eyelid in an adolescent boy.

Reappraisal of morphological and immunohistochemical spectrum of intracranial and spinal solitary fibrous tumors/hemangiopericytomas with impact on long-term follow-up.

BACKGROUND: Hemangiopericytomas (HPCs) and solitary fibrous tumors (SFTs) are unique entities in the central nervous system (CNS) and even rarer in the spine with propensity to recurrence and metastasis. Both these tumors were detected to share the NAB2-STAT6 fusion gene with frequent morphologic overlap that necessitated the need for the combined term SFT/HPC in the CNS by the World Health Organization (WHO) in 2016. AIMS: This study aims to describe the clinical outcome of intracranial and spinal SFT/HPCs based on detailed histomorphologic and immunohistochemical features. MATERIALS AND METHODS: A retrospective analysis of these tumors was conducted over a period of 10 years from January 2006 to January 2017 at our institute. Based on the elaborative assessment of morphology and immunohistochemistry, these tumors were categorized into three grades as per WHO criteria. RESULTS: A total of 13 cases were encountered involving mainly extra-axial and supratentorial regions. Among intracranial HPCs, anaplastic subtypes constituted significantly higher proportion (39%) when compared with peripheral HPCs. Peculiar morphological patterns like micropapillae and pseudoangiomatous arrangement of tumor cells were observed in high-grade tumors. A panel of immunomarkers were used to confirm the diagnosis and rule out other mimickers. Gross total resection was achieved in 54% (7/13) of the cases with local recurrence observed in 31% (4/13). Grade II tumors showed recurrence in 28% cases. No case showed distant metastasis. CONCLUSION: To conclude, not just clinical parameters but morphologic features such as unusual patterns, mitosis, and proliferative index also play a pivotal role in predicting the clinical behaviour of SFT/HPC.
