Published: August 2023

The relevance of the work is due to the lack of systematic data on the features of lung damage in patients with chronic obstructive pulmonary disease (COPD) and type II diabetes mellitus (DM2).Aim: To identify the main radiation phenotypes of lung tissue damage in patients with chronic obstructive pulmonary disease and type II diabetes mellitus.Material and Methods. We conducted a one-stage observational study, with the analysis of clinical data, laboratory and instrumental studies (pulmonary function tests, computed tomography), in patients with chronic obstructive pulmonary disease in combination with type II diabetes mellitus (57 people).Results. In patients with a combination of COPD and type II diabetes mellitus, the predominance of predominantly bronchitic type of COPD over emphysematous was revealed, with the presence of statistically significant links between a number of patterns (the presence of air trapping, bronchiolitis) and laboratory results (the number of eosinophils in the blood, the number of leukocytes in the blood and sputum, the number of macrophages in sputum, levels of IL-33, TNF-α, CRP, IFN-γ/IL-4 ratio), which may reflect the influence of different pathogenetic aspects of inflammation on the formation of structural changes in the lung tissue).Conclusion. For patients with a combination of chronic obstructive pulmonary disease and type II diabetes mellitus, the presence of a bronchitic COPD phenotype with the absence of confluent and destructive forms of pulmonary emphysema is more characteristic. The wide prevalence of the bronchitic COPD phenotype in patients with concomitant type 2 diabetes mellitus may be due to predominant changes in the small airways, the development of microangiopathy, as well as an infectious factor, since patients with type 2 diabetes mellitus, in general, are more susceptible to infections, including respiratory.

Published: August 2023

El acróstico APACHE (Acral Pseudolymphomatous Angiokeratoma of Children) corresponde a una variante de los seudolinfomas cutáneos. El término fue introducido por Ramsay, et al., en 1988, cuando publicaron cinco casos de pacientes pediátricos con múltiples pápulas angiomatosas, unilaterales, que se localizaban en la región distal de las extremidades. En el estudio histopatológico se observaba un infiltrado dérmico linfohistiocitario nodular con capilares prominentes.En la actualidad, los nombres de “seudolinfoma de pequeñas pápulas” o “hiperplasia angiolinfoide papulosa” serían los más convenientes, ya que no siempre se presenta en niños, es de localización distal o se observan cambios angiomatososen el estudio de histopatología.Se presenta el caso de una niña con una lesión distal en el segundo dedo del pie izquierdo, cuyo diagnóstico de angioqueratoma distal seudolinfomatoso infantil se hizo mediante el estudio histopatológico. Además, se hacen comentarios sobreesta rara entidad.

Background & Objective: Birth asphyxia is a leading cause of brain damage. Early identification and managing of its contributing factor would change the burden of birth asphyxia. Therefore, the objective of this study was to identify the determinants of birth asphyxia among newborn in a zonal hospital, Dhanusha, Nepal.
Material and Methods: A case control study was carried out among 192 newborns where cases and controls were taken in the ratio of 1:1. Newborns with an APGAR score of less than 7 at 1 min and 5 min were taken as cases, and those with greater or equal to 7 were taken as controls. Case includes all asphyxiated newborns at time of data collection. There were total 96 birth asphyxiated newborn and equal number of non-asphyxiated newborn meeting the inclusion criteria were included as a control group. Data was collected by using structured interview schedule and chart review. The data was entered into SPSS version 16. The data were analyzed by frequency, percentage, mean, standard deviation, chi-square test and odd ratio. Those variables with a p-value <0.05 were identified as significant determinants of birth asphyxia.
Results: Findings revealed that rural residency (79.2%), dalit ethnicity (69.6%) and joint family (92.7%) were socio-demographic determinants of birth asphyxia. Finding also revealed that primi-parity (OR:3.2,95%CI:1.7-8.2),problem during pregnancy(OR:3.1,95%CI:1.5-6.6), premature rupture of membrane (OR:23.4, 95%CI: 8.7-62.7), augmentation of labour with oxytocin (OR:12.3, 95%CI:6.1-24.4), sex of newborn (OR:5.0, 95%CI;2.7-9.4), meconium stained amniotic fluid (OR:0.22,95%CI:0.00-0.05), cord round the neck (OR:19.0,95%CI:2.4-24.6) and height of mother (OR:16.2,95% CI:2.0-126.0) were significantly associated with increase odds of birth asphyxia.
Conclusion: Most of the identified determinants were common and familiar causes of birth asphyxia. Early detection can prevent and control birth asphyxia. Thus, every pregnant woman need for better maternal care, so creating awareness about determining factors of birth asphyxia to the midwives, careful monitoring of labour, and identifying and taking proper measures that would help in decreasing the occurrence of birth asphyxia.

Published: August 2023

Introduction: Neoadjuvant chemoradiation (NACRT) may result in significant response in rectal cancer. Conventional imaging may not be accurate. 18FDG-PET/CT scan has shown promising results for monitoring the response to NACRT. The aim of this study is to evaluate the role of 18FDG-PET/CT scan in predicting pathological response after NACRT in carcinoma rectum.
Methods: Thirty-two consecutive patients with locally advanced rectal cancer were enrolled. Patients underwent NACRT comprising of external beam radiotherapy and concomitant infusional 5-FU based chemotherapy. It was followed 6 weeks later by total mesorectal excision. All patients underwent FDG-PET/CT before and minimum 6 weeks after the completion of NACRT. Maximum standardized uptake (SUVmax) value was calculated. The tumor regression grade (TRG) in resected specimen was scored according to the Mandard criteria. TRG 1-2 was considered as responders and TRG 3-5, non-responders. The SUVmax within the tumor was correlated to differentiate pathological responders from non-responders.
Results: Fourteen of 30 patients were excluded due to protocol deviation. Following NACRT, 7 (50%) patients were classified as responders (TRG 1-2) and 7 (50%) non-responders (TRG 3-5). There were no significant differences in pre NACRT SUVmax between responders (12.05±2.81) and non-responders (17.65±7.20) (p=0.079). The mean post-NACRT SUVmax was significantly lower in responders than non-responders (6.4 vs 10.8; p=0.024). To compare the response using ROC curve analysis (AUC=0.83), and considering a cut-off post SUVmax as 7.0, the sensitivity was 57.14%, specificity 71.43%, positive predictive value (PPV) 66.67%, negative predictive value (NPV) 62.50%, and the overall accuracy was 64.28% to differentiate pathological responders from non-responders.
Conclusion: These preliminary results suggest that 18FDG-PET/CT could be a potentially useful tool in predicting response after NACRT in locally advanced rectal cancer. Post SUVmax of 7.0 appears to be the best predictor tumor response following NACRT.

Published: August 2023

Introduction: During hanging maneuver liver resection, a tunnel is created at the interface of the liver and Inferior venacava (IVC). Gap between the middle and right hepatic vein is known as Fossa venacava. A gap between the Inferior right hepatic vein and the Caudate vein is known as a Vein gap. The Fossa venacava and Vein gap provide a safe plane for the insertion of forceps during tunneling. The aim of this study is to determine the topography of this safe plane.
Methods: A cross-sectional study was done. Twenty livers were used in our study. Major hepatic veins, distance of Vein gap, Fossa venacava, and each vessel present at the interface between liver and IVC was measured by a Vernier caliper. All the collected data was entered and analyzed by using Statistical Package for Social Sciences version 20 (SPSS-20).
Results: The average length of retro hepatic IVC was 49.5±10.5 mm and the diameter of 25.6±4.4 mm. The inferior right hepatic vein was present in 60% of cases while the Caudate vein was present in 85% of cases. Fossa venacava had an average distance of 12.3±3.46 mm and the Vein gap was 18.9±7.1 mm.
Conclusion: While tunneling between IVC and the liver, Fossa venacava could be as small as 4.6 mm. The shortest distance of the Vein gap could be as small as 5.8 mm. The intermediate course of forceps insertion is safer than the right or left course.
Colonic Mucormycosis In A Post Covid Patient: A Case Report

Published: August 2023

Mucormycosis is rare infection caused by fungi of order Mucorales which frequently involves rhino-cerebral or respiratory system with involvement of gastrointestinal (GI) tract being rare.
Classically majority of patients with invasive mucormycosis are immunocompromised and/or have poor glycemic control. This happens especially during recovery phase of COVID-19 when patients are immunocompromised and simultaneously having poor glycemic control. While gastrointestinal (GI) mucormycosis is rare, stomach and colon are most commonly affected organs, and mortality can be as high as 85%.
Diagnosis is difficult since signs and symptoms, imaging and intraoperative gross appearance may not suggest mucormycosis. Diagnosis is usually by histopathologic identification of fungal hyphae in biopsy specimen. A high index of suspicion is therefore necessary in post-COVID-19 patients presenting with mesenteric ischemia or bowel perforation especially if they were immunocompromised. Here we present a case of post COVID disseminated mucormycosis in a 59-year-old diabetic male patient.
