Trends of humoral immune responses to heterologous antigenic exposure due to vaccination & omicron SARS-CoV-2 infection: Implications for boosting

Background & objectives: Vaccination and natural infection can both augment the immune responses against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), but how omicron infection has affected the vaccine-induced and hybrid immunity is not well studied in Indian population. The present study was aimed to assess the durability and change in responses of humoral immunity with age, prior natural infection, vaccine type and duration with a minimum gap of six months post-two doses with either ChAdOx1 nCov-19 or BBV152 prior- and post-emergence of the omicron variant. Methods: A total of 1300 participants were included in this observational study between November 2021 and May 2022. Participants had completed at least six months after vaccination (2 doses) with either ChAdOx1 nCoV-19 or an inactivated whole virus vaccine BBV152. They were grouped according to their age (? or ?60 yr) and prior exposure of SARS-CoV-2 infection. Five hundred and sixteen of these participants were followed up after emergence of the Omicron variant. The main outcome was durability and augmentation of the humoral immune response as determined by anti-receptor-binding domain (RBD) immunoglobulin G (IgG) concentrations, anti-nucleocapsid antibodies and anti-omicron RBD antibodies. Live virus neutralization assay was conducted for neutralizing antibodies against four variants – ancestral, delta and omicron and omicron sublineage BA.5. Results: Before the omicron surge, serum anti-RBD IgG antibodies were detected in 87 per cent participants after a median gap of eight months from the second vaccine dose, with a median titre of 114 [interquartile range (IQR) 32, 302] BAU/ml. The levels increased to 594 (252, 1230) BAU/ml post- omicron surge (P<0.001) with 97 per cent participants having detectable antibodies, although only 40 had symptomatic infection during the omicron surge irrespective of vaccine type and previous history of infection. Those with prior natural infection and vaccination had higher anti-RBD IgG titre at baseline, which increased further [352 (IQR 131, 869) to 816 (IQR 383, 2001) BAU/ml] (P<0.001). The antibody levels remained elevated after a mean time gap of 10 months, although there was a decline of 41 per cent. The geometric mean titre was 452.54, 172.80, 83.1 and 76.99 against the ancestral, delta, omicron and omicron BA.5 variants in the live virus neutralization assay. Interpretation & conclusions: Anti-RBD IgG antibodies were detected in 85 per cent of participants after a median gap of eight months following the second vaccine dose. Omicron infection probably resulted in a substantial proportion of asymptomatic infection in the first four months in our study population and boosted the vaccine-induced humoral immune response, which declined but still remained durable over 10 months

Epidemiology, Clinical Profile, Intensive Care Needs and Outcome in Children with SARS-CoV-2 Infection Admitted to a Tertiary Hospital During the First and Second Waves of the COVID-19 Pandemic in India

Objectives To compare the epidemiological, clinical profle, intensive care needs and outcome of children hospitalized with SARS-CoV-2 infection during the frst and second waves of the pandemic. Methods This was a retrospective study of all children between 1 mo and 14 y, admitted to a dedicated COVID-19 hospital (DCH) during the frst (1st June to 31st December 2020) and second waves (1st March to 30th June 2021). Results Of 217 children, 104 (48%) and 113 (52%) were admitted during the frst and second waves respectively. One hundred ffty-two (70%) had incidentally detected SARS-CoV-2 infection, while 65 (30%) had symptomatic COVID-19. Comorbidities were noted in 137 (63%) children. Fifty-nine (27%) and 66 (30%) children required high-dependency unit (HDU) and ICU care respectively. Severity of infection and ICU needs were similar during both waves. High-fow oxygen (n=5, 2%), noninvasive ventilation [CPAP (n=34, 16%) and BiPAP (n=8, 5%)] and invasive ventilation (n=45, 21%) were respiratory support therapies needed. NIV use was more during the second wave (26% vs. 13%; p=0.02). The median (IQR) length (days) of DCH stay among survivors was longer during the frst wave [8 (6–10) vs. 5.5 (3–8); p=0.0001]. Conclusions Disease severity, associated comorbidities, PICU and organ support need and mortality were similar in the frst and second waves of the pandemic. Children admitted during the second wave were younger, had higher proportion of NIV use and shorter length of COVID-19 hospital stay.

Use of dry blots for serotyping and genotyping of dengue viruses: A pilot study

Background & objectives: Dengue (DEN) is a result of infection by one or multiple types of four dengue viruses known as Dengue virus (DENV) 1-4. Identifying circulating serotype and genotype is epidemiologically important, however, it is challenging in resource limited areas. Moreover, transporting samples from the collation site to the laboratory in appropriate condition is an exigent task. To overcome this, we evaluated the usefulness of dry blots of serum for DENV diagnosis, serotyping and genotyping. Methods: Serum samples received for diagnosis were divided into parts; one was used for providing the diagnosis. Remaining sample was distributed in three parts (100 µl each), one part was used for molecular testing and two parts were mixed with RNAlater reagent® in equal volumes and was blotted on Whatman filter paper no 3. The blots were dried and stored at 4°C and 28°C and tested for presence of dengue RNA, serotypes and genotypes after 7 days of incubation. Results: The diagnosis and serotyping results of serum sample and dry serum blots were in concordance. Out of 20 positive samples, 13 (65%) gave satisfactory sequencing results. Genotype III of DENV-1, Genotype IV of DENV 2 and Genotype I of DENV-4 were detected. Interpretation & conclusion: The results demonstrate that serum mixed with RNA protective solution and blotted on Whatman filter paper no 3 can be effectively used for diagnosis, serotyping and genotyping of DENVs. This will help in easy transportation, diagnosis and effective data generation in resource limited settings.

Preoperative assessment of inferior vena cava collapsibility index by ultrasound is not a reliable predictor of post-spinal anesthesia hypotension

Abstract Background Post-spinal anesthesia hypotension is of common occurrence, and it hampers tissue perfusion. Several preoperative factors determine patient susceptibility to hypotension. This study aimed to assess the effectiveness of the Inferior Vena Cava Collapsibility Index (IVCCI) for predicting intraoperative hypotension. Methods One hundred twenty-nine adult patients who were scheduled for elective surgical procedures after administration of spinal (intrathecal) anesthesia were included in the study. Ultrasound evaluation of the Inferior Vena Cava (IVC) was done in the preoperative area, and the patients were shifted to the Operating Room (OR) for spinal anesthesia. An independent observer recorded the change in blood pressure after spinal anesthesia inside the OR. Results Twenty-five patients developed hypotension (19.37%). Baseline systolic blood pressure and mean blood pressures were statistically higher in those patients who developed hypotension (p= 0.001). The logistic regression analysis for IVCCI and the incidence of hypotension showed r2 of 0.025. Receiver Operating Characteristic (ROC) curve analysis demonstrated the Area Under the Curve (AUC) of 0.467 (95% Confidence Interval, 0.338 to 0.597; p= 0.615). Conclusions Preoperative evaluation of IVCCI is not a good predictor for the occurrence of hypotension after spinal anesthesia.

Role of melatonin in attenuation of hemodynamic response to intubation and anesthetic requirements: a randomized, controlled, double-blind study

Abstract Background Melatonin has been studied to have anxiolytic, sedative, and analgesic effects. However, there is limited data on the effect of melatonin in the attenuation of hemodynamic response to intubation. We aimed to study whether preanesthetic oral melatonin attenuates hemodynamic responses to intubation and anesthetic requirements. Methods Sixty-four patients scheduled for laparoscopic cholecystectomy were randomized into melatonin or placebo group (n = 32 each). Melatonin group received two tablets (3 mg each) of melatonin, and the placebo group received two tablets of vitamin D3 120 min before induction. Hemodynamic parameters were recorded during induction and postintubation for 15 minutes. Total induction dose of propofol, total intraoperative fentanyl consumption, and adverse effects of melatonin were also noted. Results Postintubation rise in heart rate (HR) was less in the melatonin group compared to the placebo group (10.59% vs. 37.08% at 1 min, respectively) (p< 0.0001). Maximum percentage increase in systolic blood pressure (SBP), diastolic blood pressure (DBP), and mean blood pressure (MBP) was lesser in melatonin group than placebo group (SBP 9.25% vs. 37.73%, DBP 10.58% vs. 35.51%, MBP 9.99% vs. 36.45% at 1 min postintubation. respectively) (p< 0.0001). Induction dose of propofol (1.42 mg.kg-1 vs. 2.01 mg.kg-1) and the number of patients requiring additional fentanyl intraoperatively (3 vs. 11) were also significantly reduced in the melatonin group. Conclusion Premedication with 6 mg of oral melatonin resulted in significant attenuation of postintubation rise in HR, SBP, DBP, and MBP. It also reduced the induction dose of propofol, total intraoperative fentanyl consumption without any adverse effects.

Blood pressure trend of lowlanders during first 6 days of acclimatisation to high altitude

Objectives: The present study was planned to delineate the blood pressure (BP) response of the lowlanders during initial 6 days of acclimatisation to high altitude. Materials and Methods: 398 normotensive sojourners at sea level ascended to HA (3,500 m). Blood pressure response of these subjects were analysed for 6 consecutive days at HA. Based on the BP response of these subjects on the 6th day at HA they were divided into two groups: HBP-high BP group and NBP- normal BP group. Results: It showed that on 6th day at HA, 51 out of 398 subjects presented with BP?140/90 mmHg (HBP) while others remained normotensive (NBP). Comparative systolic BP of HBP and NBP groups during successive days at HA were as follows: HA day 1 (146.8 ± 13.7 mmHg vs 146.3 ± 8.8 mmHg, p>0.05), HA day 4 (144.5 ± 8.7 mmHg vs 135.0 ± 7.0 mmHg, p<0.05) and HA day 6 (148.1 ± 7.9 mmHg vs 131.7 ± 5.3 mmHg, p<0.05). Whereas, diastolic BP of HBP and NBP groups were: HA day 1 (94.0 ± 8.1 mmHg vs 93.2 ± 6.6 mmHg, p>0.05), HA day 4 (88.9 ± 6.0 mmHg vs 85.3 ± 5.1 mmHg, p<0.05) and HA day 6 (93.8 ± 6.3 mmHg vs 83.7 ± 3.8 mmHg, p<0.05). Conclusion: It was found that NBP had initially raised BP which returned to normal levels after acclimatisation period of 6 days, but in HBP, it started rising after 4th day. It can be concluded that those individuals whose BP on 6th day at HA does not return to normal after acclimatisation period needs regular follow up as these individuals can have a delayed acclimatisation normalising BP later on or can become hypertensive subsequently

Do children with severe acute respiratory infection need cohorting & isolation before screening for COVID-19?

This retrospective analysis was done to ascertain the SARS-CoV-2-positivity rate in children (0-12 yr) with severe acute respiratory infection (SARI) and compare it to those without SARI to determine the need for running a dedicated SARI isolation facility for paediatric COVID-19 care. The case records of 8780 children (0-12 yr) admitted and/or tested for SARS-CoV-2 between June 2020 and May 2021 at a tertiary care centre in north India were analyzed. The overall SARS-CoV-2 reverse transcription (RT)-PCR positivity rate was 3.0 per cent (262/8780). There were 1155 (13.15%) children with SARI. Fifty of these 1155 (4.3%) children with SARI, as against 212 of the 7625 (2.8%) children without SARI, tested positive for COVID-19. The absolute difference in the positivity rate among SARI and non-SARI groups was only 1.54 per cent which translates to cohorting and isolating 65 children with SARI to pick up one extra SARS-CoV-2-positive child (compared to those without SARI). The positive predictive value of SARI as a screening test was 4.3 per cent. Our findings suggest that isolation of children with SARI as a transmission-prevention strategy for COVID-19 may not be required. This is particularly relevant in resource-limited settings.

Spatial Epidemiology of COPD in Delhi, India

Introduction?Chronic obstructive pulmonary disease (COPD) and bronchial asthma are the most common chronic respiratory illnesses. COPD is one of the three most common causes of death worldwide. The main burden of mortality from COPD is seen in Latin America, sub-Saharan Africa, India, China, and South-East Asia. Absence of true prevalence values and mortality burden hinder planning and operationalization of public health interventions for prevention, control, and treatment of the disease. Further, the aggregated value of prevalence estimates calculated for a whole city or a larger geographical area does not provide the location of patients and presence of locally prevalent risk factors. The objective of this study was to understand the spatial distribution of COPD in a large, highly polluted city of a developing country. Materials and Methods?A cross-sectional community-based study was conducted in the National Capital Territory of Delhi (NCTD). All surveyed households were geocoded. GOLD screening criteria and pulmonary function tests using portable digital spirometer were used for diagnosis of COPD. Results?Results are presented as a series of maps depicting spatial epidemiology. Overall prevalence rate was 9.8/1,000 population. Highest prevalence was seen in industrial area. Most of the spatial hotspots were seen in industrial and slum areas. Similarly, Kernel density was also highest in industrial area. Conclusion?In the city of NCTD, we found the COPD being distributed in all types of habitations but spatial distribution helped us understand clustering of cases and compare prevalence rates in subunits of residential clusters within a metropolitan city.

Exploratory analysis of the suitability of data from the civil registration system for estimating excess mortality due to COVID-19 in Faridabad district of India

Background & objectives: Due to shortcomings in death registration and medical certification, the excess death approach is recommended for COVID-19 mortality burden estimation. In this study the data from the civil registration system (CRS) from one district in India was explored for its suitability in the estimation of excess deaths, both directly and indirectly attributable to COVID-19. Methods: All deaths registered on the CRS portal at the selected registrar’s office of Faridabad district in Haryana between January 2016 and September 2021 were included. The deaths registered in 2020 and 2021 were compared to previous years (2016-2019), and excess mortality in both years was estimated by gender and age groups as the difference between the registered deaths and historical average month wise during 2016-2019 using three approaches – mean and 95 per cent confidence interval, FORECAST.ETS function in Microsoft Excel and linear regression. To assess the completeness of registration in the district, 150 deaths were sampled from crematoria and graveyards during 2020 and checked for registration in the CRS portal. Agreement in the cause of death (CoD) in CRS with the International Classification of Diseases-10 codes assigned for a subset of 585 deaths after verbal autopsy was calculated. Results: A total of 7017 deaths were registered in 2020, whereas 6792 deaths were registered till 30 September 2021 which represent a 9 and 44 per cent increase, respectively, from the historical average for that period. The highest increase was seen in the age group >60 yr (19% in 2020 and 56% in 2021). All deaths identified in crematoria and graveyards in 2020 had been registered. Observed peaks of all-cause excess deaths corresponded temporally and in magnitude to infection surges in the district. All three approaches gave overlapping estimates of the ratio of excess mortality to reported COVID-19 deaths of 1.8-4 in 2020 and 10.9-13.9 in 2021. There was poor agreement (?<0.4) between CoD in CRS and that assigned after physician review for most causes, except tuberculosis and injuries. Interpretation & conclusions: CRS data, despite the limitations, appeared to be appropriate for all-cause excess mortality estimation by age and sex but not by cause. There was an increase in death registration in 2020 and 2021 in the district.

Coughing up: “Adenosquamous carcinoma lung with unusual initial presentation as an ulceroproliferative growth” - case report and review of literature

Lung carcinoma is the most common carcinoma seen in males with the skin being a rare metastatic site. Adenosquamous carcinoma as a rare histologic subtype, showing cutaneous metastasis is an unusual event with no reports in the literature till date. Skin metastasis is an alarming sign, carries poor prognosis, and is associated with shortened survival. Herein, we report a case of 60-year-old male who presented with isolated cutaneous metastasis as a chronic nonhealing ulcer over the sternal region for 3 years (unusual) in the first place, without any other associated symptoms and clinical evidence of the primary. Wide local excision of the lesion was performed after proper workup which revealed metastatic adenosquamous carcinoma. The patient was advised systemic chemotherapy. A high index of suspicion along with clinico-radio-pathological correlation in these cases is of utmost importance and forms the basis of accurate diagnosis

Role of multidetector computed tomography angiography in evaluation of peripheral arterial disease

Background: Diagnostic imaging plays an important role in the evaluation of peripheral arterial disease. Many imaging modalities are available ranging from conventional modalities to the cross-sectional modalities like Doppler ultrasound, DSA, CT and MRI. The main principles of imaging are to characterize the all lesions detected including type of plaques, no. of lesions, length of stenosis, diameter of vessel in pre-stenotic and post-stenotic segments, degree of wall calcification, assisting in pretreatment planning with respect to route of access, selection of balloon and demonstrates size, extent, neck dimention, and presence of thrombosis in cases with aneurysm.Methods: A Cross-sectional observational study was done in 30 patients. Clinically suspected patients of peripheral arterial disease based on history, sign and symptoms and patients diagnosed with peripheral arterial disease on color doppler were included in our study. Both modalities were compared for detecting the occlusion and stenotic segments.Results: A total of 476 vessel segments were imaged by both modalities. When all arterial segments were considered, MDCTA detected stenosis or occlusion lesions in 30% of arterial segments, versus 18.8% compared to DUS. MDCTA showed 9.8% (95% CI:[4.3%, 15.3%]) more lesions than DUS when all arterial segments were considered together, 11.2% (95% CI: [2.7%, 22.1%]) more lesions when only the iliac arteries were compared, 9.1% (95% CI: [3.2%, 17.2%]) more lesions when only the femoropopliteal arteries were compared, 8.9% (95% CI: [1.5%, 16.3%]) more lesions when only infrapopliteal arteries were compared and 13% (95% CI: [2.6%, 25.4%]) more lesions when only the upper limb arterial segments were compared, (p <0.05 for all comparisons).Conclusions: MDCTA may be used as a screening tool in patients with peripheral arterial disease as it is a non-invasive and more accurate modality when compared to DUS and plays important role in management.

Giant peptic ulcer perforation- omentopexy versus omental plugging: a comparative study

Background: Giant peptic ulcer perforation is a life-threatening surgical emergency with high mortality rate. This study compares two different surgical techniques omentopexy and omental plugging for the treatment of giant peptic perforation.Methods: This study was a prospective study comparing the efficacy of omental plugging and omentopexy. The study was done at Emergency Department of General Surgery in Nalanda Medical College and Hospital, Patna over one-year period from October 2017 to September 2018. Patients were randomly allocated to two groups: one for omental plugging (cases) and other for omentopexy (controls).Results: A prospective non-randomized study of 12 patients with giant peptic perforation (≥2 cm in diameter) was carried out over a period of 24 months. The highest incidence was seen in males over 50 years of age. Biliary leak rates were 33% in the omentopexy group compared to no leak in the omental plugging group. This rate when calculated on standard error of proportion was significant at 5% level (p<0.05). Mortality rate was higher in omentopexy group compared to omental plugging group.Conclusions: Omental plugging seems to be associated with low rates of biliary leak compared to omentopexy and hence should be the procedure of choice in giant peptic ulcer perforation compared to omentopexy.

Curse of the technology-computer related musculoskeletal disorders and vision syndrome: a study

Background: Computer Related Musculoskeletal disorders and Vision Syndrome (CRMSKVS) is defined as symptoms due to prolonged use of Visual Display Terminal (VDT).Methods: A cross-sectional observational study was done among office-workers working on computer terminal. A self-reported questionnaire was distributed and Musculoskeletal (MSK) and visual symptoms in the preceding 12 months (01 October 2017 to 30 September 2018) were taken as dependent variable. Multivariate analysis was done to identify the determinants of CRMSKVS.Results: Responses from 1193 subjects were included in the study. CRMSKVS was present in 489 cases (40.98%; males - 37.5%, females - 58.29%).  The main MSK symptoms were pain/stiffness in neck (40.98%), shoulder (38.99%), lower back (35.6%) and elbow/wrist/hand/fingers (23.1%). The ocular symptoms were excessive watering (39.6%), pain (24.99), irritation (18.6%), burning/itching sensation (29.8%), redness (40.7%), blurring of vision (13.2%) and headache (40.9%). Female gender (OR-1.498(1.262-1.778)), long duration of working hours (OR-2.77(2.399-3.214)), poor break duration (OR-2.59(2.172-3.089)), excessive smart phone use (OR-2.071(1.834-2.338)), poor posture (OR-3.883(3.282-4.592)), inappropriate distance of computer screen (OR-2.173(1.829-2.582)), low height of screen (OR-1.936(1.527-2.454)), distance of keyboard (OR-3.161(2.528-3.953)) and distance of mouse (OR-5.785(3.932-8.512)) were identified as significant determinants of CRMSKVS.Conclusions: CRMSKVS is an emerging pandemic which needs urgent attention by medical and administrative authorities. The device factors, personal factors, environmental and ergonomic factors are the modifiable risk factors for CRMSKVS.

Bacteriological Profile and Antimicrobial Susceptibility Patterns of Bacteria Isolated from Surgical Site Infections of Patients Attending a Tertiary Care Hospital

Introduction: Surgical site infections (SSIs) are one of themajor causes of morbidity and mortality in developing countriesdespite recent advances in aseptic techniques. The SSIs dueto emerging multidrug resistance (MDR) bacteria isolates areconsidered as grave threats to the public health worldwide.Each hospital has specific type of microbial flora from whichinfection initiates. In such condition microorganism showsunique type of antibiotic susceptibility and resistance pattern.In this study we report on the microbiological spectrum ofSSIs and the antimicrobial susceptibility pattern with a viewto provide guide to the clinicians for making rational decisionover the choice of antibiotics in the management of surgicalsite infection.Material and Methods: This cross-sectional study wascarried out in a tertiary care hospital and the 560 sampleswere collected, processed in the microbiology laboratory andevaluated for the study.Results: Out of 376 growth positive samples, Gram NegativeBacilli (GNB) were isolated from 271 (72%) samples andGram Positive Cocci (GPC) were isolated from 105 (28%)samples. Among the isolated GNB, only 5 to 10% weresensitive to third generation Cephalosporins. Sensitivity toFluroquinolones (Ciprofloxacin and Levofloxacin) was alsolow (Only 5% to 10% were sensitive). Only 3 to 15% of theGNB were found sensitive to Co-amoxiclav and 6.5% to 23%were sensitive to Ampicillin-Sulbactam. About 60% of thePseudomonas aeruginosa and about 40% of the Klebsiellaspp and Acinetobacter baumanii were found resistant toMeropenem.Conclusion: Gram Negative Bacilli predominated overGram Positive Cocci in surgical site infections in our setup. Very low sensitivity to 3rd generation Cephalosporins,Ampicillin, Co-amoxiclav and Fluroquinolones was notedamong GNB isolates and an increasing pattern of resistanceto Aminoglycosides and Carbapenems was also noted amongMDR Pseudomonas aeruginosa and Acinetobacter baumaniiisolates. More than 50% of the MDR Acinetobacter spp.were was found sensitive to Ampicillin- Sulbactam andMinocycline.

DNA base excision repair genes variants rs25487 (X-ray repair cross-complementing 1) and rs1052133 (human 8-oxoguanine glycosylase 1) with susceptibility to ovarian cancer in the population of the Jammu region, India

Background: Ovarian cancer is highly prevalent in the population of Jammu, in India; the ovarian cancer ranks third among other types of cancer prevalent in females. However, association studies on ovarian cancer are lacking in this region. We aimed to investigate the disease susceptible variants rs1052133 (human 8-oxoguanine glycosylase 1 [hOGG1]) and rs25487 (X-ray repair cross-complementing 1 [XRCC1]) with ovarian cancer in population of Jammu, India. Materials and Methods: The study conducted in the Shri Mata Vaishno Devi University is a 3-year study which included a total of 280 well-characterized samples (130 ovarian cancer cases and 150 healthy controls). hOGG1 and XRCC1 polymorphisms were determined by polymerase chain reaction-based restriction fragment length polymorphism, and these genotyping results were confirmed by Sanger sequencing. Hardy–Weinberg equilibrium for both single-nucleotide polymorphisms (SNPs) was assessed using the Chi-square test. The allele and genotype-specific risks were estimated by odds ratios with 95% confidence intervals. Results: In this preliminary study, SNP rs1052133 showed protection with ovarian cancer (P = 0.042). The SNP rs25487 was not found associated with ovarian cancer (P = 0.271). Conclusion: Our results indicate that the G allele of rs1052133 imparts protection to the population whereas variant rs25487 was not associated with ovarian cancer in population from the Jammu region, indicating that larger sample size is needed for further statistical validation. Further, association of other SNPs in these genes should also be carried out as their role cannot be ruled out.

Collodion baby-congenital ichthyosis: clinical review

Collodion baby is a rare form of congenital ichthyosis in which the entire body is covered by a parchment-like membrane. These neonates are at the risk of dehydration, sepsis, electrolyte disturbances, and temperature instability. It is inherited in autosomal recessive manner. We report a case of Collodion baby, born of a consanguineous marriage. Here, we present a short review of this condition and the various methods available for the prenatal diagnosis. A literature search was done using PubMed, Medline, and Google Scholar databases using the mesh terms 'Ichthyosis', 'collodion baby', 'collodion membrane', 'Congenital ichthyosiform erythroderma', and 'Lamellar ichthyosis'.
