The g factor of an isomeric state at 2738 keV in 135La has been measured by time differential perturbed angular distribution technique. This isomer was populated in the reaction 128Te(11B, 4n)135La at beam energy of 52 MeV. We performed the large-scale shell-model (LSSM) calculations which successfully describe the low-lying levels and band structures of 135La. The measured value of the g factor,-0.049(3), has been compared with the LSSM result to firmly assign the configuration of the isomeric state. The major configuration of 23/2+ state is π(d5/2)⊗ν(h11/2)-2. [ABSTRACT FROM AUTHOR]

The high-spin states in 133Cs, populated using the reaction 130Te(7Li,4n) with 45-MeV beam energy, have been extended up to an excitation energy of 5.265 MeV using the Indian National Gamma Array. The observed one- and three-quasiparticle bands in 133Cs, built on the πh11/2,πg7/2, πd5/2; and (πg7/2πd5/2)1⊗νh-211/2 configurations, respectively, have similar structure as seen in the lighter odd-A Cs isotopes. The experimental level scheme has been compared with the large-scale shell model calculation without truncation using the jj55pna interaction, showing a good agreement for both positive- and negative-parity states.

Abstract: The lifetimes of high spin states of 75Kr have been determined via 50Cr (28Si, 2pn) 75Kr reaction in positive parity band using the Doppler-shift attenuation method. The transition quadrupole moments deduced from lifetime measurements have been compared with 75Br. Experimental results obtained from lifetime measurement are interpreted in the framework of projected shell model. [Copyright &y& Elsevier]

Objectives: The a im of this study is to evaluate and compare the efficacy of Nigella sativa (75% v/v) cream and clobetasol propionate (0.05% w/w) gel for the management of oral lichen planus (OLP)., Study Design: Sixty clinically diagnosed cases of OLP were stratified into moderate cases or severe cases based on burning sensation before getting allocated to group I receiving Nigella sativa cream and group II receiving clobetasol propionate gel, two times a day for 45 days. Patients were examined every 15 days for a change in burning sensation and size of the lesion using the numeric pain rating scale (NRS) and a standard Vernier caliper, respectively. Statistical tests including Mann-Whitney U, Wilcoxon signed-rank, Friedman's, Dunn's post hoc, unpaired t, paired t, one-way repeated measures ANOVA, and Bonferroni's post hoc were applied., Results: There was a statistically significant reduction in the burning sensation as well as the size of the lesion in both groups (P ≤ 0.05). There was an 87.8% (moderate cases) and 85.7% (severe cases) reduction in the mean NRS scores on the 45th day in group I when compared to the 96.5% (moderate cases) and 93.48% (severe cases) in group II. There was a 92.9% (moderate cases) and 90.7% (severe cases) reduction in the size of the lesion in group I when compared to the 92.6% (moderate cases) and 93.1% (severe cases) in group II., Conclusion: The topical application of Nigella sativa cream was effective and comparable to clobetasol propionate 0.05% gel in the management of OLP, without any side effects. Hence, this study recommends the use of topical Nigella sativa cream therapy in the management of OLP., Clinical Relevance: The current mainstay of treatment for OLP is the administration of topical or systemic corticosteroids, which are known to cause side effects, demanding a search for an alternative. Nigella sativa oil cream could be a safe, promising, cost-effective, adjunctive, or alternative modality. Clinical trial registration number: CTRI/2020/07/026745 (India)., (© 2022.

Actinomycotic osteomyelitis is a rare chronic suppurative, granulomatous, fibrosing saprophytic infection. It is an endogenous infection caused by the Actinomyces species, which are part of the normal oral microflora. There is a male predilection for this type of infection, with the male to female ratio of 4:1. Though the etiopathogenesis of the infection is unclear, it is mostly attributed to the disruption of the normal oral microflora and the invasion of the microorganism into deeper tissues through a break in the mucosal barrier due to damage from trauma, extraction or previous injury. The portal of entry can be through the pulpal, periodontal or mucosal route, causing the purulent and necrotic infection of soft tissue, bone, or both. The diagnosis is usually considered when there is a persistent infection without the presence of regional lymphadenopathy and is usually confirmed through the histopathological depiction of the bacterial colonies - 'ray fungus' - as obtaining the positive culture of the causative microorganisms is difficult and is reported to be effective in less than 50%. Patients with such infections are managed with surgical debridement, followed by antibiotic therapy for a longer time period. Recent advances have been emphasized for an early diagnosis and a better prognosis of the therapy. Therefore, this paper aimed to present a rare case of actinomycotic osteomyelitis of the maxilla in a 45-year-old female patient, and also to review the literature on this rare infection.

Background: The prognosis of head &neck cancer (HNC) depends on its early detection, diagnosis, and treatment, which has advocated a search for a simple, reliable, noninvasive, cost-effective tool to aid in the same. Salivary lactate dehydrogenase has gained interest in recent years, meeting the above requisite., Objectives: To evaluate the levels of salivary lactate dehydrogenase in patients with oral potentially malignant disorders (OPMD), HNC, and in the healthy control group (CG); to find the correlation, grade-wise and genderwise difference between them; and to assess whether it can be used as a potent biomarker in OPMD and HNC., Materials and Methods: A comprehensive search of the specialized 14 databases and 4 institutional repositories was performed for including the studies evaluating salivary lactate dehydrogenase in OPMD and HNC patients either comparing or not comparing to the healthy control group in the systematic review process. The meta-analysis was performed with the eligible study data with the STATA version 16, 2019 software with 95% CI and p ≤ 0.05 in the random-effects model., Results: Twenty-eight studies of case-control, interventional, or uncontrolled non-randomized design evaluating salivary lactate dehydrogenase were included. A total of 2074 subjects were included, involving HNC, OPMD, and CG. The salivary lactate dehydrogenase levels were significantly higher in HNC than in CG & oral leukoplakia (OL) (p=0.00); in OL & oral submucous fibrosis (OSMF) than CG (p=0.00); and higher in HNC than OSMF, however not significant (p=0.49). Also, the salivary lactate dehydrogenase levels had no significant difference between males and females in CG, HNC, OL, and OSMF groups(p> 0.05)., Discussion: It is evident that the epithelial transformations in the various OPMD and HNC, and the proceeding necrosis in the case of HNC, raises the LDH levels. It's also worth noting that when degenerative alterations continue, the SaLDH levels rise correspondingly, which are higher in HNC than in OPMD. Hence, it is essential to determine the cut-off values for SaLDH for establishing that the patient may have HNC or OPMD. It would be easy to follow-up frequently and perform investigations such as biopsy for the cases with high SaLDH levels, thereby aiding in the early detection and improving the prognosis of HNC. Moreover, the increased SaLDH levels were indicative of a lower degree of differentiation and an advanced disease leading to a poor prognosis. Salivary sample collection is less invasive, simple, and more acceptable to the patient; however, saliva collection is a time-consuming procedure as it is mostly collected by the passive spit method. Also, it is more feasible to repeat the SaLDH analysis during the follow-up, but the method has recently gained interest for over a decade., Conclusion: Salivary lactate dehydrogenase can be a potential biomarker for the screening, early detection, and follow-up of OPMD or HNC being simple, noninvasive, cost-effective, and readily acceptable modality. However, more studies with new standardized protocols are recommended to determine the precise cut-off levels for HNC and OPMD.

Context: Oral submucous fibrosis (OSMF) is a chronic insidious oral potentially malignant disorder characterized by increased collagen deposition and reduced collagen degradation causing burning sensation and difficulty in mouth opening., Aim: To assess the efficacy of topical Tulsi (Ocimum sanctum) paste for the management of OSMF., Settings and Design: Institution-based clinical trial., Materials and Methods: The study included a total of 60 OSMF patients categorized into three Groups A, B and C (20 in each) depending on the severity according to Lai DR et al. classification. The patients were advised for topical Tulsi paste application and were evaluated for the reduction in the burning sensation and improvement in mouth opening every month for 3 subsequent months using the numeric pain rating scale (NRS) and a Vernier calliper, respectively., Statistical Analysis: The baseline and 3-month recordings were subjected to inter- and intra-group statistical analysis using Kruskal-Wallis analysis of variance (ANOVA), Mann-Whitney U, one-way ANOVA, Tukey's multiple post-hoc and Wilcoxon matched-pairs tests., Results: There was a reduction in the burning sensation and improvement in the mouth opening in all three groups. The reduction in the burning sensation was statistically significant among all the groups (P < 0.05) and the NRS scores after 3 months among the three groups were not statistically significant (P > 0.05). There was a statistically significant difference (P < 0.05) in the improvement of mouth opening between Group A and B; A and C; but not between B and C., Conclusion: Tulsi paste showed a significant reduction in the burning sensation and improvement of the mouth opening thereby proving to be a safe and promising medicament for OSMF., Competing Interests: None

Context: Oral lichen planus (OLP) is a quite common chronic inflammatory mucocutaneous disorder affecting the oral cavity and skin. The current treatment relies on systemic or topical corticosteroids but is known to cause side effects thereby demanding a search for an alternative., Aim: This study aims to assess and to compare the efficacy of topical Coconut (Cocos nucifera) 50% cream and Clobetasol propionate 0.05% ointment for the management of OLP., Settings and Design: An institution-based double-blinded randomized control trial., Materials and Methods: Sixty clinically diagnosed OLP patients were allotted to two groups (30 in each): Group I (Coconut cream-50%) and Group II (Clobetasol Propionate ointment-0.05%). Patients were examined every 15 days until two months for a change in the lesion size and reduction in the burning sensation. The measurement of lesion size and burning sensation was done using Adobe Photoshop software (version CS3) and Numeric Pain Rating scale (NPS), respectively., Statistical Analysis Used: The recordings were subjected to the statistical analysis using Wilcoxon matched-pairs and Mann-Whitney U tests for intra-group and inter-group comparisons, respectively., Results: There was an 85% regression in the size of the lesion in Group I whereas Group II had it to be 95%, and a 100% reduction in the NPS score in Group I whereas Group II had it to be 95%., Conclusion: The Coconut cream showed a significant decrease in the size of the lesion and the burning sensation with no side effects neither any signs of toxicity reported during the treatment or follow-up, thereby proving to be a safe and promising medication for OLP., Competing Interests: None

Gorlin-Goltz syndrome or basal cell nevus syndrome is a comparatively rare syndrome characterized by basal cell nevi, odontogenic keratocysts, and skeletal anomalies. Diagnosis is based on the major and minor clinical and radiographic criteria. Dentist plays a major role in the diagnosis of this disease due to the oral and maxillofacial manifestations of the syndrome. In some cases, jaw cysts are diagnosed by routine radiographs advised by the dentists. Odontogenic keratocysts in such syndromic patients will be multiple and extensive and in some cases results in cortical expansion and facial disfigurement. Thorough clinical examination and investigations prompt an early confirmation of the syndrome, which is very essential to avoid morbidity associated with the syndrome. Here, we report a case of multiple odontogenic cysts in a 16-year-old patient which later was diagnosed as a case of Gorlin Goltz syndrome.
