Rapid Cytological Diagnosis With Evaluation of Pre- and Post-Therapeutic Fungal Morphological Characteristics in Mucormycosis.

Background: Mucormycosis necessitates rapid diagnosis and treatment. Microscopy and culture have been considered the gold standard for diagnosis but both take time of 3 - 5 days. KOH mount is another method for fungal identification that takes 1 - 2 h, but it has its own limitations. This study evaluated crush smear as a means of rapid cytological diagnosis. Methods: Biopsy tissue (pre-treatment) from clinically suspicious mucormycosis patients (n = 52) was received in normal saline and crush/imprint smears were prepared; the remaining tissue was processed as routine biopsy specimen. After the rapid initial cytological identification, the patients were managed according to the standard clinical protocol. Random post-therapeutic biopsy samples of some of these patients (n = 19) were also obtained and again evaluated cytologically. Results: Crush smears showed sensitivity/specificity of 77.7%/75.0% with histopathology and 72.2%/62.5% with culture, respectively, while KOH mount had values of 71.4%/70.5% with histopathology and 79.3%/69.5% with culture, respectively. Degenerative fungal morphological characteristics and cellular inflammatory infiltrate (predominantly neutrophilic) in the vicinity of fungal hyphae were compared in pre- and post-treatment groups, and we found a statistically significant difference (P < 0.05) between them. Conclusion: Our preliminary results suggest that crush smear cytology is a simple, rapid, cost-effective and easily available method for diagnosing mucormycosis. Moreover, crush smears also demonstrated morphological alteration in hyphal structure and accompanying immune cell infiltration which may provide valuable insights into mechanism of therapy/host immune response against fungal pathogen.

Prevalence of hepatitis B & C infections in prospective blood donors deferred due to history of jaundice.

Background & objectives: As per national guidelines, prospective blood donors with a history of jaundice of unknown cause are deferred permanently to prevent the transmission of hepatitis B and C. The validity of this guideline was tested by comparing prevalence rates of hepatitis B and C in prospective blood donors deferred due to a history of jaundice, with that of donors who were found fit. Methods: Blood samples of 212 consecutive donors (male, n=203) deferred due to a history of jaundice were studied for hepatitis B and C by rapid test kits as well as by chemiluminescence (n=115) or ELISA (n=97). Consecutive healthy donors (n=549; male, n=518) were also studied by ELISA (n=266) or chemiluminescence (n=283). Results: The cumulative prevalence detected by rapid test kit and ELISA/chemiluminescence tests of hepatitis B (n=10) and C (n=2) among donors deferred due to a history of jaundice (n=212) was 5.7 per cent [95% confidence interval (CI): 2.9, 9.9]. The prevalence of reactive results among healthy donors (n=549) by ELISA/chemiluminescence tests was 3.3 per cent (95% CI: 1.9, 5.2), which included hepatitis B (n=15) and hepatitis C (n=3) cases. Compared to healthy donors, the odds of seropositivity among jaundice-deferred donors was 1.7 (95% CI: 0.8, 3.6), P=0.15. For rapid test-negative deferred donors, the odds of seropositivity by ELISA/chemiluminescence declined to 0.4 (0.1, 1.5), P=0.19. Interpretation & conclusions: The prevalence rates of hepatitis B and C in prospective blood donors deferred due to a history of jaundice of unknown aetiology did not differ significantly from that in healthy donors. The current practice of permanently deferring such donors depletes valuable donor pool. A strategy of rejecting only those donors who are found reactive on pre-donation testing by rapid test needs further validation.

Role of ferritin and oxidative stress index in gestational diabetes mellitus.

OBJECTIVES: To investigate the role of serum ferritin and oxidative stress in the development of GDM and to assess their relationship with the ensuing hyperglycemia. METHODS: A case-control study was carried on 90 non-anemic pregnant women of 20-40 years with a gestation of 24-28 weeks. Study group (n = 65) was identified according to the Diabetes in Pregnancy Study Group India (DIPSI) criteria (2-h plasma glucose ≥ 140 mg/dl) and controls (n = 25) having 2-h plasma glucose < 120 mg/dl. DIPSI 2-h plasma glucose, HbA1c and serum ferritin were measured and oxidative stress index (OSI) was calculated. Statistical tests were performed using SPSS version 25.0. RESULTS: Pre-pregnancy BMI showed a significant difference between control and study group. DIPSI 2 h blood glucose, HbA1c, serum ferritin and OSI were significantly higher in study group compared to control group. Both 2 h blood glucose and HbA1c were positively correlated with serum ferritin and OSI, serum ferritin and OSI were also positively correlated with each other. CONCLUSION: Higher pre-pregnancy BMI elevates serum ferritin, which in turn increases the OSI. Both ferritin and oxidative stress raises 2 h blood glucose and HbA1c in GDM patients possibly by causing in-vivo pancreatic ß -cell injury and death (ferroptosis). Serum ferritin and OSI could become newer personalized theranostic and monitoring targets in overweight/obese pregnant females especially GDM patients.

Mandibular mucormycosis following SARS-CoV-2 infection - A case report and review of literature.

BACKGROUND: The second wave of COVID-19 pandemic has seen an unprecedented rise in the number of mucormycosis cases worldwide and in India particularly. This otherwise rare fungal infection has become an endemic among patients who have recovered from recent SARS-CoV-2 infection. Among the different types of mucormycosis, rhino-orbital-cerebral involvement has mainly been observed in the recent surge of cases. Very few cases of mucormycosis of mandible have been reported in literature and none in COVID-19 patients. We report a case of isolated mandibular mucormycosis in a COVID- 19 patient, with no other predisposing comorbidities.Case report.A 39 year old patient recently recovered from COVID-19 presented with typical symptoms of osteomyelitis which was confirmed using computed tomography of face. He underwent thorough debridement and curettage and tissue was sent for culture, special staining and biopsy. RESULT: Diagnosis of mucormycosis was confirmed based on postoperative biopsy and special staining. He was further managed with complete course of appropriate antifungal therapy. CONCLUSION: Mucormycosis is a fulminant and aggressive infection which requires prompt diagnosis and intervention. Early referral to a maxillofacial surgeon by physicians and general dental practitioners on seeing signs and symptoms of secondary fungal infections involving maxilla or mandible in patients with history of SARS-CoV-19 infection can improve prognosis.

Restarting Thalidomide-Dexamethasone Regimen in a Post-Abortive Female with Multiple Myeloma: Effective Clinical Response Possible.

Nowadays, the prevalence of Multiple Myeloma (MM) seems to have been increasing among young females. Here, we report that thalidomide is contraindicated in pregnant women diagnosed with MM and those desirous of subsequent pregnancy. In this case report, we compared the clinical response of Thalidomide-Dexamethasone therapy in a post-abortive woman with persistently elevated ß-hCG levels due to retained products of conception, undergoing hysterectomy later. This case report underlines the clinical significance of age, the effect of Thalidomide-Dexamethasone therapy even after initial discontinuation and the response to high ß-hCG levels.

Smear patterns and spectrum of premalignant and malignant cervical epithelial lesions in postmenopausal Indian women: a hospital-based study.

Cervical cancer is one of the leading causes of morbidity and mortality among women but can be prevented through simple cost-effective measures, such as creating awareness, and regular screening with the Pap smear, both in the premenopausal and postmenopausal age group. This study was carried out to study the cervical smear patterns and type of cervical epithelial lesions in a group of postmenopausal Indian females and the relationship with clinical profile of patients. Pap smears were taken from 320 postmenopausal Indian females and meticulously screened. Lesions were classified according to type of postmenopausal pattern. 120 smears showed varying degrees of premalignant and malignant changes, which were classified using the Bethesda system. The findings were correlated with duration of menopause, parity, and duration of sexual activity and significance was derived. Histopathological correlation was conducted in those cases where biopsies were available. It was found that as the age of the patients increased, the incidence of low-grade and high-grade squamous intraepithelial lesions and carcinoma also increased with the relationship being statistically significant. The occurrence of these lesions also showed an association with increasing parity and period of sexual activity. Thus, it can be concluded that it is important to create widespread awareness about the necessity of regular screening, including the postmenopausal period. Conventional cytology or the Pap smear is a cost-effective and efficient method for screening of patients but requires training and experience to minimize errors. It is suitable for developing regions where costlier techniques are not in routine use.

Thrombocytopenia and bacterial sepsis in neonates.

Thrombocytopenia is one of the common hematological problems encountered in the neonatal period particularly in the sick newborns, premature babies and neonates admitted in neonatal intensive care units and usually indicate an underlying pathologic process. Thrombocytopenia is reported in neonates with bacterial, fungal, rickettsial, protozoal and viral infection. Some patients with bacterial septicemia may develop coagulopathy associated with DIC. The presence of thrombocytopenia is seen frequently in early sepsis with or without laboratory evidence of overt DIC. This study was conducted on 85 neonates admitted in NICU with clinical diagnosis of septicemia and 50 age and weight matched neonates served as control. Thrombocytopenia was seen in 83.5% cases where as bacterial culture was positive in only 41.1% cases. Further it was noted that, in gram negative (Gm -ve) septicemia, thrombocytopenia was more severe as compared to gram positive (Gm +ve) septicemia. It is concluded that thrombocytopenia is early predictor of septicemia but other causes of neonatal thrombocytopenia should also be ruled out.

Epithelioid cell cluster in cerebrospinal fluid: an unusual finding in tubercular meningitis.

Tubercular meningitis is one of the serious manifestations of tuberculosis. It remains a significant contributor to the morbidity and mortality in children. Meningeal involvement in tuberculosis is detected by physical, chemical and cytological examination of cerebrospinal fluid (CSF). The cytological picture of CSF in tubercular meningitis is quite similar to that of viral meningitis showing a mixed population of lymphoid series cells. The presence of epithelioid cell cluster is very rare finding. We present here such a case of 2(1/2) yr old boy who presented with fever off and on for 2 months and altered sensorium along with vomiting for 2-3 days.

Intradural extramedullary primary hydatid cyst of the spine in a child: a very rare presentation.

Spinal hydatid cyst is a serious but fortunately uncommon manifestation of the parasite Echinococcus, involving less than 1% patients with hydatid disease. Intradural hydatid cysts are extremely rare compared to other types of spinal hydatid cysts. We report a rare case of intradural, extramedullary spinal hydatid cyst in a 9-year-old male boy, who presented with weakness of both lower limbs for the last 4 months that was confirmed histopathologically; a better understanding of this rare but clinically challenging disease is intended by reporting this case.

Sickle cell disease and malaria.

Malaria is most common infectious disease spread by female Anopheles mosquitoes especially in tropical and subtropical areas of the world. It is reported by WHO as a 4th leading cause of death in children across the developing countries. Unfortunately no vaccine is currently available. Sickle cell trait (HbAS) patients provide some resistance for malaria over normal persons (HbAA) or their homozygous state (HbSS) due to various reasons.

Serum immunoglobulin levels in neoplastic disorder of breast.

Serum IgG, IgA and IgM were estimated in 42 cases of carcinoma and 12 cases of fibroadenoma of breast. The results were compared with 20 healthy female controls. Results showed increased levels of serum IgA in carcinoma breast cases. This increase was statistically significant (p = 0.001) when compared with healthy controls while IgG and IgM values were found to be insignificant. Values of IgG, IgA and IgM in cases of fibroadenoma breast when compared with the controls were found to be insignificant. Statistically significant increased value of IgA was also observed in medullary carcinoma and non-metastasizing tumours when viewed separately, suggestive of good prognostic index of serum IgA level estimation in the case of carcinoma breast.
