Authors: Couppoussamy Kanmani Indra , Devanda Rajendra 
Published: August 2024

Abstract

Background:
Dermatitis cruris pustulosa et atrophicans (DCPA) is a chronic superficial folliculitis that can cause scarring alopecia if left untreated. Hardly any studies are there describing the dermoscopic features of DCPA. Dermoscopy can be a useful tool for diagnosing DCPA in addition to clinical and histopathological features and for differentiating other conditions like superficial folliculitis, folliculitis decalvans, and pseudofolliculitis.

Aims/Objectives:
The aim of this retrospective study was to describe the dermoscopic features of 30 patients with DCPA at a tertiary care center in South India.

Materials and Methods:
A retrospective study of clinical and biopsy-proven cases of DCPA at a tertiary care center in South India.

Results:
Thirty patients of DCPA of skin phototype IV or V were studied. Male preponderance of DCPA was noted in our study. Lower extremities 28 (93.3%) and upper extremities 2 (6.7%) were the common sites of involvement. The most common findings noted in dermoscopy were follicular-based pustules in 30 (100%) patients, follicular white structureless area in 16 (53.3%), perifollicular collarette of scales in 12 (40%), diffuse background dotted blood vessels in 12 (40%), and the absence of follicular orifices in 12 (40%). Other findings were yellow or hemorrhagic scales, perifollicular linear white lines, broken hair, and perifollicular dotted blood vessels. Pigmentary patterns observed were dark brown pigmentation, blue–grey globules, blue–grey dots, and accentuation of the pigmentary network.

Limitations:
The limitations of the study were the retrospective nature of the study, the small sample size, and the lack of a comparison group.

Conclusion:
The predominant dermoscopic features observed in our patients were follicular-based pustules, follicular white structureless areas, perifollicular collarette of scales, diffuse background dotted blood vessels, and the absence of follicular orifices. Vascular and pigmentary patterns were less commonly noted.

Published: August 2024

Abstract:

BACKGROUND:
One of the complications of blood transfusion is the development of red cell alloimmunization. Little published literature on the prevalence and actual significance of red cell alloantibodies among nonregularly transfused patients and the general population.

OBJECTIVES:
This study aimed to estimate red cell alloantibodies’ prevalence, specificity, and clinical significance in obstetric and medical practice in Iraq.

MATERIALS AND METHODS:
A cross-sectional hospital-based study involving internal medicine patients and ladies in obstetric wards of Baghdad Teaching Hospital in Baghdad/Iraq, from January 2022 to May 2022. Demographic data were collected along with detailed medical, obstetric, and transfusion history. Alloantibody screening was performed, and samples with positive results were subjected to antibody titration and identification.

RESULTS:
A total of 200 patients were enrolled. Indirect antiglobulin test was positive in 15% of patients in internal medicine wards and 23% of ladies in obstetric wards, with most of the identified alloantibodies being clinically significant, against Kidd and Duffy antigen groups. Blood transfusion of more than four units to patients at internal medical wards showed a significant association as a risk for developing red cell alloantibodies (P = 0.025). For ladies in obstetric wards, there was a significant association between pregnancy loss at the time of screening and alloimmunization (P = 0.0164).

CONCLUSION:
High prevalence of red cell alloantibodies in comparison to what is published worldwide. Transfusion of more than four units of blood and pregnancy loss at the time of screening were statistically significant risks for alloimmunization of the medical and obstetric populations, respectively.
Anti-phosphohistone H3 (PHH3) as a proliferation marker to assess mitotic activity and to grade neuroendocrine neoplasms of hepatopancreaticobiliary (HPB) system

Published: August 2024

ABSTRACT

Background:
The world health organization (WHO) classification of neuroendocrine neoplasms (NENs, i.e. neuroendocrine tumors (NETs) and neuroendocrine carcinomas (NECs)) of the gastrointestinal system involves grading of these tumors by mitotic count (i.e. H and E mitotic index or Haematoxylin and Eosin mitotic index [HE-MI] and Mindbomb E3 ubiquitin protein ligase 1 labelling index (MIB1-LI) into Grade 1 (G1), Grade 2 (G2), or Grade 3 (G3). However, the assessment of HE-MI and MIB1-LI is hindered by several factors that contribute to discordance between these two grading methods. Clinical data demonstrate the dependency of prognosis on grade.

Objectives:
The objective of this study was to compare the grading of NENs of the hepatopancreatobiliary (HPB) system using Anti-phosphohistone H3 mitotic index (i.e. PHH3-MI), HE-MI and MIB1-LI.

Materials and Methods:
In a cohort of 140 NENs selected from January 2011 to August 2019, the concordance and correlation between HE-MI, MIB1-LI and PHH3-MI grading methods were analysed using Cohen’s weighted kappa (
κ
) statistics and Spearman’s correlation (ρ), respectively. Receiver operating characteristic (ROC) curve and cut-off analyses were done to determine optimal PHH3-MI cut-off values to grade NENs.

Results:
The rates of discordance between HE-MI vs. MIB1-LI, PHH3-MI vs. MIB1-LI and PHH3-MI vs. HE-MI were 52% (
κ
=0.416), 29% (
κ
=0.64) and 41% (
κ
=0.508), respectively. There was a significant correlation between the grading methods. PHH3-MI had good overall sensitivity and specificity at cut-offs 2 and 17 in distinguishing between G1 vs. G2, and G2 vs. G3 tumors, respectively.

Conclusion:
PHH3 immunolabeling allowed for quick and easy identification of mitotic figures (MF). It had the highest concordance with MIB1-LI. At cut-off values of 2 and 17, there was good overall sensitivity and specificity. The interobserver agreement was excellent.

Abstract
Spinal cord involvement is a rare complication of the schistosomiasis manifesting as myeloradiculopathy, medullary or conus–cauda equina syndrome which can lead to potentially serious long-term disability. Computed tomography and magnetic resonance imaging coupled with biochemical parameters have become the mainstay of diagnosis. Biopsy which is the gold standard of diagnosis demonstrating the organism is usually reserved for cases of diagnostic challenge. We report a rare case of upper thoracic spinal cord schistosomiasis diagnosed by biopsy in an 18-year-old male migrant presenting to a spine and orthopaedic centre in Ghana with complaints of upper back pain and associated myeloradiculopathy symptoms. Initial suspicion of intramedullary cord tumour was made based on magnetic resonance imaging findings warranting biopsy which revealed schistosoma spp. He was treated with anthelminthics and corticosteroids with a resolution of symptoms.
Tuberculous meningitis causing holocord longitudinally extensive transverse myelitis
Authors: Dev Nishanth , Kumar Rahul , Kumawat Ashok , Singh Gaurav 
Published: August 2024

ABSTRACT
Longitudinally extensive transverse myelitis (LETM) is a neurological entity with characteristic inflammatory lesions in ≥3 vertebral segments of the spinal cord. It is most commonly associated with neuromyelitis optica spectrum disorder. Other causes include infections, autoimmune disorders, and neoplasms. Tuberculosis has been reported as a cause of LETM in few case reports. However, tuberculous meningitis (TBM) as a cause of LETM is extremely rare, more so with involvement of the complete spine cord from the brainstem to the conus medullaris. A 65-year-old female was admitted to our hospital with sudden-onset tetraplegia and sensory, bowel, and bladder involvement. With no significant past history, mild meningeal signs, and normal metabolic profile, cerebrospinal fluid analysis was done revealing polymerase chain reaction test positive for Mycobacterium tuberculosis. Magnetic resonance imaging of the spine was suggestive of complete spinal cord edema extending from the brainstem to the level of conus medullaris without skip lesions. A final impression of holocord LETM caused by TBM was suggested after ruling out other causes. The case highlights TBM as a potential cause of LETM especially in endemic countries, especially Asian and African countries, more so with holocord involvement without skip lesions.

ABSTRACT
Thyroid nodules are a common occurrence in the Indian population. The current management involving an individualized approach is increasingly becoming relevant instead of a broad diagnostic and management algorithm. The consensus statements derived in this article aim to provide a summary of the current medical evidence for the diagnosis and management of thyroid nodules, which assists in optimizing recommendations in the Indian setting. The task force of experts has provided inputs to address specific clinical questions in this consensus. The statements are formulated after a thorough analysis of several published studies and guidelines to address the screening, diagnosis, and management of thyroid nodules. A well-defined grading system is used to appraise the evidence and grade the strength of recommendations. This guideline covers risk stratification of thyroid nodules (differentiating benign from malignant lesions) and a guide to the use of fine-needle aspiration cytology to improve definitive management. The guideline covers evidence-based recommendations for the management of benign, cytologically indeterminate, and malignant thyroid nodules. The panel has also touched upon the aspects of nondiagnostic thyroid nodule management and intraoperative neuromonitoring. These evidence-based expert consensus statements can provide useful and practical insights to aid the practicing clinician.

different partial orders, known as the
higher Stasheff–Tamari orders
. The first of these orders was introduced by Kapranov and Voevodsky, while the second order was introduced by Edelman and Reiner, who in 1996 also conjectured the two to coincide. In this paper, we prove their conjecture, thereby substantially increasing our understanding of these orders. This result also has ramifications in the representation theory of algebras, as established in previous work of the author. Indeed, it means that the two corresponding orders on tilting modules,

Abstract
The global agreement at the UN COP-26 meeting urges all countries to gradually phase out the use of raw coal. Therefore, coal downstreaming is necessary. The coal product industry (KBLI 19100) in Indonesia will have a growing significance in the times ahead. However, currently, the concentration of the coal product industry is still high due to the limited number of companies in this sector. This study aims to analyze the impact of industry concentration and input costs on efficiency in the coal product industry (KBLI 19100) in Indonesia. The data used are secondary data sourced from the Central Statistics Agency (BPS) from 2010-2021, using a regression model to test the influence of independent variables on industrial efficiency. The results of this study indicate that industry concentration and input costs have a significant negative effect on efficiency. This means that if industry concentration and input costs increase, efficiency will decrease.

Full Abstract
Enterobacteriaceae is a family of Gram-negative, oxidase-negative, and catalase-positive bacteria mostly found in Humans and animals' intestines. Some of these organisms are enteric opportunistic pathogens associated with urinary tract infections, respiratory tract infections, and wound infections, whereas others are regularly pathogenic for humans. This study aimed to determine the prevalence of Enterobacteriaceae in clinical samples from Federal Teaching Hospital Gombe between August 2022 and November 2022. A total of 420 non-duplicate isolates from various clinical samples were analyzed in the study. The isolates were identified based on cultural characteristics, Gram staining, and standard biochemical tests. Out of the 420 isolates identified, Escherichia coli was the most prevalent with 163(38.8%) isolates, followed by Klebsiella pneumoniae with 69(16.4%), Klebsiella oxytoca with 61(14.5%), Proteus spp. 28(6.7%), Citrobacter spp. 27(6.4%), Enterobacter spp. 22(5.2%), Serratia marcescens 13(3.1%), Providencia spp. 12(2.9%), Yersinia enterocolitica 11(2.6%), Morganella morganii 3(0.7%) and Salmonella spp. with 2(0.5%). Based on clinical specimens, urine had the highest percentage of isolates with 53.4%, followed by wound swab (19.1%), stool (10.1%), High vaginal swab (6.8%), Endocervical swab (3.6%), sputum (3.1%), blood (1.4%), Cerebrospinal fluid (1.0%) and semen (1.0%) and then pleural fluid (0.5%). In conclusion, Enterobacteriaceae clinical isolates were highly prevalent in Federal Teaching Hospital Gombe.

Electronically Controlled Broadband Terahertz Amplitude Modulator Based on Ionic Liquid/PEDOT:PSS:DMSO Composite Structure
Authors: Liu Yangqi , Zhang Bo , Zhang Yan 
Published: August 2024

Electronically controlled modulation devices operating in the terahertz (THz) band offer a crucial foundation for the integration and minimization of THz systems. In this work, we offer a broadband THz amplitude modulator that can be electrically controlled. The modulator is based on a composite structure made of ionic liquid and polymer mixture poly (3-ethoxythiophenyl): poly (4-phenylsulfonate) (PEDOT:PSS:DMSO). By applying merely +4 V excitation and −4 V turn-off voltage, a 40% amplitude modulation depth may be produced in the frequency region of 0.1–1.5 THz due to the joint action of electrons in the polymer and ions in the ionic liquid. The measurement of the resistance change of the polymer surface provides an explanation and confirmation of the mechanism of polymer action in this occurrence. This work provides a material selection for a simple preparation, inexpensive, and effective modulation of THz amplitude for an ionic liquid gate electronically controlled THz modulator. It is also expected that this work can be helpful for the miniaturization and integration development of THz modulators.

Penelitian ini memiliki tujuan untuk mengetahui dampak sosial dan ekonomi pembangunan dari krisis Pandemi Covid-19 di Kota Jember. Virus Covid-19 yang menyebar semenjak tahun 2020 membawa dampak yang signifikan terhadap pola mata pencaharian masyarakat di Jember. Di awal pandemi dampak paling dirasakan oleh ibu rumah tangga yang bertahan hidup mencoba membantu suami mereka bekerja sampingan seperti jualan makanan, sayuran dan lain sebagainya. Cara tersebut dilakukan guna memperbaiki perekonomian yang sempat anjlok tidak bisa beroperasi, sebagaimana pekerjaan utama kepala keluarga mereka banyak dilakukan di rumah masing-masing dan pekerja di PHK oleh industri. Guna memperbaiki pembangunan yang semakin lama semakin dilakukan, maka partisipasi ekonomi masyarakat juga harus diperhatikan. Faktor yang penting adalah kualitas diri dari sumber daya manusia itu sendiri menentukan kreativitas ketika dalam situasi mendadak. Metode yang digunakan oleh penelitian ini yaitu studi literatur dari beberapa jurnal terkait pembahasan dampak sosial, ekonomi serta pembangunan. Dengan tujuan mencari tahu sebesar apa dampak yang terjadi kepada masyarakat sehingga dapat dicari jalan keluar atau solusi terbaik untuk memulihkan keadaan.
