Mini-implant assisted orthodontic correction of lip and occlusal cant of a young adult: A case report.

Patients seek orthodontic treatment to correct unesthetic and asymmetric smiles because even a minimal cant of 4 is well perceived by a layperson. This case report describes a nonsurgical orthodontic management of iatrogenic occlusal canting in a 22-year-old female, who developed it during a previous orthodontic treatment for an impacted canine. The iatrogenic cant was corrected by the intrusion of the left mandibular segment followed by extrusion of left maxillary segment using mini-implants. Mini-implants were inserted in the mandibular left buccal segment (the first between canine and premolar, the second between the second premolar and first permanent molar), and the intruded mandibular posteriors were stabilized with the help of stainless-steel ligature (0.012″ SS) tied to the mini-implant. The expected correction of the occlusal cant, asymmetric gingival and tooth exposure, and soft tissue lip cant were corrected resulting in a significant improvement in smile aesthetics at the end of orthodontic treatment. After a follow-up period of 24months, the results were stable.

Acute liver failure with a massive upper GI bleed meeting the criteria of MIS-C.

Multisystem inflammatory syndrome in children (MIS-C) is a known complication of COVID-19. There is still limited knowledge about this condition. Here, we report the case of a previously healthy toddler boy, who presented with acute liver failure and duodenal lesions resulting in severe haematemesis and haemorrhagic shock, requiring intensive care unit care. The patient had persistent transaminitis, a deranged coagulation profile, inflammatory markers were elevated, and laboratory tests were negative for common infectious hepatitis aetiologies as well as COVID-19 Reverse transcription polymerase chain reaction. His COVID-19 antibody was reactive. Upper gastrointestinal endoscopy revealed a Forrest grade III duodenal ulcer. Looking into the constellation of symptoms and laboratory findings a confirmed diagnosis of acute viral hepatitis caused by MIS-C was made. Hence, he was given intravenous methylprednisolone along with intravenous immunoglobulins, after which he improved clinically and transaminitis resolved. The patient was discharged on clinical improvement and was doing fine on follow-up up to 6 months.

Meta-analysis: High pooled positive predictive value of the European Society of Paediatric Gastroenterology, Hepatology and Nutrition no-biopsy approach for coeliac disease testing in children.

BACKGROUND: The European Society of Paediatric Gastroenterology, Hepatology and Nutrition established guidelines in 2012 for a no-biopsy approach to diagnose coeliac disease in children. This guideline required symptoms suggestive of coeliac disease, positive human leukocyte antigen (HLA) DQ2/DQ8 haplotypes, tissue transglutaminase type-2 immunoglobulin A antibody titre at levels greater than 10 times the upper limit of normal, and positive endomysial immune-globulin A antibody test. An updated 2020 guideline excluded the need for symptoms and positive HLA. AIMS: To assess the pooled positive predictive value (PPV) of the no-biopsy approach with small bowel biopsy (SBB) data as the reference standard for comparison. METHODS: Database searches (October 2023) provided data that we combined using a random-effects meta-analysis to provide a pooled PPV, representing the probability that a positive test result means that an individual truly has the condition. RESULTS: We included 23 studies. Study sample sizes totalled 23,769 but only 3007 children had comparative SBB. The proportion of coeliac disease confirmed by the no-biopsy approach and SBB ranged from 79.2% to 100%, with an overall pooled PPV of 97.4% (95% confidence interval 96.0, 98.6). Sensitivity analysis showed higher PPV for the criteria that included HLA (98.5% vs. 96.8%; p = 0.017). CONCLUSION: Both no-biopsy criteria exhibit high PPV when compared to the reference standard. These results provide a consistent message of accuracy and feasibility to inform change and improve outcomes.

"The impact of orthognathic surgery on articulation proficiency and speech intelligibility in skeletal Class III malocclusion: 18 months follow up".

Introduction: Orthognathic surgery results in the positional change of the maxilla and mandible that may affect speech. The present study evaluated the effect of combined maxillary advancement and mandibular setback surgery on articulation proficiency and speech intelligibility in patients with non-syndromic skeletal Class III malocclusion. Methods: In this prospective study, twenty-five patients with skeletal class III malocclusion and consecutively treated with Lefort-1 maxillary advancement and mandibular setback (BSSO) orthognathic surgery were included in this study. The speech sample was recorded with a digital audio tape recorder one day before surgery and at 3, 6, 9, 12 and 18 months after surgery. Three qualified and experienced speech and language pathologists evaluated articulation errors and intelligibility of speech samples. Repeated One-way analysis of variance was used to compare articulation proficiency and speech intelligibility at different time intervals. Results: The substitution, omission, distortion and addition errors showed no significant changes at 3 months and 6 months. The total articulation errors decreased to zero at 9 months and no significant increase was observed till 18 months (P < 0.05). Speech intelligibility showed statistically non-significant improvement at any time interval. Cephalometric skeletal parameters SNA and N l A°. were significantly correlated with addition and total articulation errors at 18 months follow up. Conclusions: The ortho-surgical treatment improves speech (decreases. articulation errors) in most of the patients usually 6-9 months post-surgery. Speech intelligibility is not affected by bimaxillary orthognathic surgery in skeletal class III patients. The articulation errors were correlated to changes in position of maxilla.

Prognostic markers in hepatitis A-related pediatric acute liver failure and validation of the Peds-hepatitis A virus prognostic model.

OBJECTIVES: Hepatitis A virus (HAV) is the commonest cause for pediatric acute liver failure (PALF) in India. The objective of the study was to identify the predictors of mortality and to evaluate the utility of Peds-HAV model in a cohort of non-LT HAV-PALF. METHODS: The study included HAV-related PALF from two non-transplant centers. The predictors of outcome were identified by univariate analysis followed by Cox regression analysis. The prognostic accuracy of Peds-HAV model, King's College Hospital (KCH) criteria and pediatric end-stage liver disease score (PELD) were evaluated. RESULTS: As many as 140 children with PALF were included, of whom 96 (68.6%) children had HAV-PALF. On Cox regression analysis, international normalized ratio (INR) (p < 0.001), jaundice to encephalopathy (JE) interval (p < 0.001) and hepatic encephalopathy (HE) grade 3/4 (p = 0.01) were independent predictors of mortality. The mortality rates were 0% (0/42), 14.3% (3/21), 60% (9/15) and 94.4% (17/18) when none, 1, 2 or 3 criteria of the Peds-HAV were met, respectively. Peds-HAV model at a listing cut-off of  ≥ 2 criteria predicted death with 89.7% sensitivity and 89.6% specificity. In contrast, KCH criteria had a lower sensitivity of 62.1%. PELD score had a sensitivity of 89.7% and specificity of 85.1% at a cut-off of 30. The overall prognostic accuracy of Peds-HAV model (89.6%) was higher than those of KCH (83.3%) and PELD (86.5%). CONCLUSION: INR, HE grade and JE interval were independent predictors of mortality. The study provides an external validation of Peds-HAV model as a prognostic score in HAV-PALF. CLINICAL TRIAL REGISTRY NUMBER: Not applicable as this is a retrospective study.

KGHeBTA (King George's Medical University Hepatitis B Therapeutic Algorithm): A New Diagnostic and Therapeutic Algorithm and Clinico-epidemiological Spectrum of Hepatitis B.

Background: Diagnostic and therapeutic algorithms given by various societies for hepatitis B are fragmented and complex. The clinico-epidemiologic spectrum of hepatitis B is not studied with large-scale data from our region. We aimed to develop a comprehensive algorithm for the treatment of hepatitis B and study its clinico-epidemiological spectrum. Methods: From 2014-2019, the clinico-laboratory data of hepatitis B surface antigen (HbsAg)-positive patients were prospectively recorded. King George's Medical University hepatitis B therapeutic algorithm (KGHeBTA) was developed on the basis of the standard existing guidelines. The prevalence of different clinical stages of HBsAg-positive patients was calculated and their treatment records reviewed. Testing circumstances and risk factors were noted. Results: Among 1,508 data record sheets, 421 were complete. According to the KGHeBTA algorithm, 221 had detectable hepatitis B virus DNA. 21% were cirrhotic and 79% non-cirrhotic. 72% were incidentally detected asymptomatic hepatitis B, 7% were hepatitis B with acute symptoms, 0.7% were acute hepatitis B, and 22% were chronic hepatitis B. 20% patients were eligible for antivirals and 80% patients were not eligible. 32% patients were actually treated with antivirals due to the inclusion of some special indications as pregnancy and family history. Screening during various medical illnesses (40%) was the most common and during health camps (0.2%), the least common testing approach. Road-side shaving (52%) was the most common and intravenous drug abuse (0.2%) and the least common risk factor for the detection of hepatitis B in our data pool. Conclusions: HBsAg-positive patients can be easily worked up and treated based on the proposed algorithm (KGHeBTA). About one fourth to one fifth of all HBsAg-positive patients were eligible and treated with oral antivirals. Most of the patients were incidentally detected asymptomatic hepatitis B screened during medical illnesses. Roadside shaving and intravenous drug abuse were the most and the least common risk factors.

Effects of Secondary Alveolar Bone Grafting on Maxillary Growth in Cleft Lip or Palate Patients: A Systematic Review and Meta-Analysis.

To assess the effect of secondary alveolar bone grafting (SABG) on maxillary growth in patients with unilateral cleft lip or palate (UCL/P).Systematic review and Meta-analysis.Pubmed, Cochrane Library, Embase, Scopus, Web of Science and manual search was performed to assess the maxillary growth following SABG in UCL/P patients.Non-syndromic patients with UCL/P.Comparison of maxillary growth between patients with UCL/P who underwent SABG and UCL/P patients who had not undergone SABG or non-cleft control.39 of the identified 233 articles were assessed for inclusion and exclusion criteria after duplicate removal and title and abstract reading. 7 articles (1 prospective, and 6 retrospective studies) were included in the qualitative analysis and 2 articles were subjected to quantitative analysis. Four studies had a low risk of bias and three studies had a moderate risk of bias. Meta-analysis revealed a significant reduction of SNA and no significant difference in ANB in the SABG group compared to the non-cleft control group(I2 = 0%). There was no significant difference in ANB between SABG and non-cleft control; however, results showed high heterogeneity(I2 = 83%). Meta-analysis of SNA and ANB showed no significant difference between SABG and the cleft control group; however, there was high heterogeneity.The studies showed a low to moderate risk of bias. SABG causes inhibition of maxillary growth in patients with cleft lip or palate when compared to patients with non-cleft control. Due to high heterogeneity, comparison to cleft control showed insufficient evidence.

Assessment of Self-Esteem and Quality of Life in Patients with Complete Unilateral Cleft Lip and Palate Undergoing Orthodontic Treatment.

Objective: To assess the self-esteem and quality of life (QOL) in patients with complete unilateral cleft lip and palate (UCLP) who were undergoing orthodontic treatment. Materials and Methods: This cross-sectional study was conducted on a total sample of 300 individuals consisted of 150 patients with UCLP (Group I) and 150 normal controls (Group II) with an age range of 10-25 years, who were undergoing comprehensive orthodontic treatment from December 2016 to December 2018. The Self Esteem and QOL were assessed using the Rosenberg Self Esteem scale (RSE) and Modified Paediatric QOL Inventory Scale (M-PQOL), respectively, in Group I and II. Results: The comparison of overall mean scores of responses to RSE questionnaires showed nonsignificant differences for all the responses and was significant only for RSE 6 and RSE 8 in the age group of 10-15 years and 21-25 years, respectively, and nonsignificant for all other questions in all the age groups. The comparison of overall mean scores of M-PQOL for the total sample showed nonsignificant differences in Group I and II for physical functioning, emotional functioning, and school functioning domain, and were highly significant differences (P ≤ 0.001) in the social functioning domain and M-PQOL 12 and M-PQOL 21. Conclusions: This study demands a definite need of a psychologist/psychiatrist among the cleft care team to counsel the patients with cleft during orthodontic treatment for motivating them to gain self-respect and acceptance in the society as certain aspects, particularly social functioning domain made them feel different from normal children because of the functional and aesthetic problems.

Novel device for automating exchange transfusions through umbilical venous route in neonates.

Manually performed double-volume exchange transfusion (DVET) is tedious, error-prone, and may incur the risk of embolism. We aimed to develop a device that automates the DVET procedure performed through the umbilical venous route. We evaluated changes in blood passing through the device during DVET. We developed an electro-mechanical device with accessories (tubing and valve assembly) to perform a complete DVET. It comprises two syringes driven by a common pump that moves back and forth to withdraw aliquots of the patient's blood and infuse equal volumes of donor blood. In tandem, it draws donor blood from a blood bank bag and pushes the patient blood drawn from the previous cycle into a waste bag, respectively. One-way duckbill valves and a two-way pinch valve ensure the separation of the donor and patient blood. A sensor detects bubbles and clots. A dashboard displays set and measured parameters. We tested the accuracy of the delivered flow rate and volume, electrical safety, embolus detection, and changes in hematological and biochemical values. The delivered flow and volume were within 5% of the set parameters. All electrical safety parameters were within normal limits. The sensor consistently detected microbubbles and clots. There were no clinically significant differences in laboratory parameters between samples drawn directly from the blood bank bag and drawn from the exit port at 80, 100, 120, and 160 s with a fixed aliquot volume. CONCLUSIONS: Our prototype of a novel device can safely automate a DVET. Further trials of this device are warranted. WHAT IS KNOWN: • Double volume exchange transfusion is often performed manually, but this is time-consuming and error-prone. • Previous attempts at automation were not widely adopted because they involved inserting two catheters and did not have mechanisms to prevent embolism. WHAT IS NEW: • This novel device fully automates double volume exchange transfusions through a single-lumen umbilical venous catheter. • It prevents air and clot embolism and has a screen for input and output parameters and alarms.

Orthodontic emergencies and mental health of patients undergoing orthodontic treatment during COVID-19 pandemic: A questionnaire study.

Objectives: To evaluate the impact of COVID-19 pandemic on orthodontic treatment and mental health of patients undergoing orthodontic treatment and to compare their mental health with the age-matched control group. Materials and methods: 484 orthodontic patients (245 males and 239 females) and 200 age-matched control subjects were divided into two age groups. Group 1 had 14-18 years of adolescents (N = 274) and 100 control participants (Group 2) and Group 3 comprised of 19 years above adults (N = 210) and 100 control participants (Group 4). Group 1 and 3 patients filled the 4 sections of the questionnaire related to orthodontic emergencies (Sections 1-3) and mental distress (Kessler Psychological Distress Scale-Section 4), while groups 2 and 4 were asked to fill only Section-4. The comparison of mental distress on high/low Kessler scores was made using the Chi-Square test/Fisher's exact test. The factors which came out to be significant were put to bivariate logistic regression analysis. Results: The percentage of patients with high Kessler scores among Group 1 and Group 3 were 9.9% and 17.2% respectively, and their differences with age-matched control groups were non-significant. The mean differences of Kessler score were significantly higher for Group 3 compared to group 1. The higher Kessler score was associated with age, higher education, a feeling of concern for non-availability of appointments, increased treatment duration, its effect on the quality of treatment, and sabotaging of definitive future plans. Conclusions: The orthodontic treatment and emergencies may not be a significant factor contributing to increased stress among patients during the lockdown.

Success rate, treatment duration, and pain perception in the management of palatally impacted canines using the K9 and Ballista spring: a randomized clinical trial.

OBJECTIVES: To evaluate the success rate, treatment duration, and pain perceived during forced eruption of maxillary palatally impacted canines using the K9 and Ballista springs. MATERIALS AND METHODS: Thirty unilateral palatal canine impactions of moderate and difficult category as determined by KPG index (score between 10 and 19) were enrolled. Group 1 comprised canine impactions managed with K9 springs, and Group 2 comprised Ballista springs. Block randomization and opaque sealed envelopes were used for allocation. The success rate and treatment duration (application of force to ligation of the impacted canine into the initial alignment archwire) were recorded. Pain perception was evaluated on a 10-point visual analogue scale (VAS) and modified McGill Pain Questionnaire. Chi-square test and Mann-Whitney U-test were used to compare the groups. RESULTS: The success rate for eruption of palatally impacted canines was 100%. The average treatment duration was 296.13 ± 96.45 days and 311.93 ± 94.34 days, respectively for Group 1 and Group 2. VAS scale scores for pain were greater for Group 2 compared to Group1, and the differences were statistically significant at all time intervals except at T1. The frequency of none and mild pain was significantly greater at all time intervals in both groups. CONCLUSIONS: The impacted canines of moderate and difficult category were erupted with a 100% success rate and similar treatment duration with both interventions. The pain scores of Ballista springs were greater after 24 hours of force application.

Metal Release and Cytotoxicity of Different Orthodontic Bracket-Wire Combinations: An In Vitro Study.

Aim: To quantify and compare the metal ions released from different bracket-wire combinations and to assess their cytotoxicity. Materials and Methods: A total of 360 fabricated sectional fixed orthodontic appliances were divided into 6 groups. The first three groups consisted of stainless-steel brackets with stainless-steel, snickel-titanium (NiTi), and titanium-molybdenum alloy (TMA) archwires, and the other three groups were fabricated using ceramic brackets (polycrystalline alumina) with stainless-steel, NiTi, and TMA archwires. These appliances were immersed in artificial saliva (pH 6.5 ± 0.5, 37°C), for 1 week, 2 weeks, and 1 month. The nickel and chromium ions released in the artificial saliva were quantified using a flame atomic absorption spectrometer, and cytotoxicity assessment was performed using a 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl tetrazolium bromide (MTT) assay on human cervical cancer cell line. Results: The stainless-steel bracket groups displayed a significantly greater release of nickel and chromium ions compared to the ceramic bracket groups (P < 0.05). However, no significant differences were identified when comparing the three archwire types within the stainless-steel/ceramic bracket groups. At the end of 1 month, the % cell viability demonstrated by the appliances was in the decreasing order of stainless-steel-TMA > ceramic-stainless steel > stainless-steel-NiTi > ceramic-NiTi > stainless-steel-stainless steel > ceramic-TMA. Conclusion: Considerably greater release of nickel and chromium ions was observed from the appliances utilizing stainless-steel brackets compared to those employing ceramic brackets. However, no remarkable difference in the levels of nickel and chromium ions was observed when comparing the three archwires: stainless steel, NiTi, and TMA. In the cytotoxicity assessment, the ceramic-TMA combination displayed the highest level of cytotoxicity, while the stainless-steel-TMA combination displayed the least cytotoxicity.

Effect of 1% curcumin gel on myeloperoxidase activity in GCF and periodontal status in the initial phase of orthodontic tooth movement.

AIM: To explore the potential effect of locally applied 1% Curcumin on myeloperoxidase (MPO) enzymatic activity in gingival crevicular fluid (GCF) and on the periodontal status during the initial phase of orthodontic tooth movement. SETTINGS AND DESIGN: Forty patients (26 females and 14 males) aged 12-25 years who required fixed orthodontic treatment were randomly divided into two equal groups. The control and test groups were similar in the various baseline parameters, including standard oral hygiene protocol. Moreover, 1% Curcumin gel was applied around mandibular anterior teeth in the test group twice daily, from three days before to 14 days after the placement of archwires. MPO activity and periodontal status were recorded at five different time points; before placement of archwire (baseline), immediately after placement of archwire, 2 hours, 7 days, and 14 days later. STATISTICAL ANALYSIS USED: The data were analyzed using the paired t-test for intra-group differences and the unpaired t-test for intergroup differences at five different time points. Statistical significance in the intragroup and intergroup difference of Plaque and Gingival index was calculated using the unpaired t-test. RESULTS: Maximum MPO enzymatic activity in GCF was observed two hours after the placement of the archwire. MPO activity decreased slightly on the seventh day, but values were still elevated as compared to baseline. However, MPO activity came back to the values similar to baseline on day 14 in the control group and significantly lower than the baseline in the test group. The inter-group differences in clinical periodontal parameters were non-significant. CONCLUSIONS: The locally applied 1% Curcumin gel appears to decrease the MPO activity in GCF on the 14th day after placement of the archwires. However, clinical periodontal status in the initial phase of tooth movement is unaffected by curcumin if patients adhere to good plaque control.

Utility of the lateral flow urine lipoarabinomannan tuberculosis assay in patients with advanced HIV disease at antiretroviral therapy centres in Mumbai, India.

BACKGROUND: People with Advanced HIV Disease (AHD) are at higher risk of TB coinfection and mortality. However, there are challenges in TB diagnosis with the currently recommended diagnostic tools. WHO recommends lateral flow urine lipoarabinomannan (LF-LAM) assay to assist TB diagnosis among AHD patients. We assessed the utility and acceptability of using urine LF-LAM assay for TB diagnosis among patients at public Antiretroviral Therapy (ART) Centres in Mumbai. METHODS: The cross-sectional study was conducted among adult AHD patients accessing care from 17 ART centres during November,2020-June, 2021. Urine LF-LAM was offered as routine care for eligible patients in combination with standard diagnostic tests. We calculated the proportion of positive LF-LAM results by CD4 categories and TB symptoms and performed multivariable logistic regression to determine the factors associated with LF-LAM positivity. RESULTS: Among 2,390 patients, the majority (74.5%) had CD4 between 101-200 cells/mm3. The mean age was 43.7 years (SD:10.6), 68.6% were male, 8.4% had TB symptoms and 88.0% were on ART. The overall proportion of patients with urine LF-LAM positive results was 6.4%. Among PLHIV with CD4≤100 cells/mm3, the positivity was 43.0% and 7.7% in symptomatic and asymptomatic patients, respectively. Among PLHIV with a CD4>100 cells/mm3, the positivity was 26.7% and 2.7% in symptomatic and asymptomatic patients respectively. Urine LF-LAM positivity was higher among inpatients, ART naïve, patients on treatment for <6 months, symptomatic and in WHO clinical stage III/IV of HIV disease as compared to the reference categories. We detected an additional 131 TB cases with urine LF-LAM in combination with the standard diagnostic tests. CONCLUSION: The study demonstrated the utility of urine LF-LAM for TB diagnosis among AHD patients and the simple, user-friendly test was acceptable as part of routine care. Inclusion of urine LF-LAM test in the current diagnostic algorithm may facilitate early TB diagnosis among AHD patients.

Evaluation of Quantitative Aspects of Craniofacial Deformities in Transfusion Dependent Beta-Thalassemia Major Patients: A Cephalometric Study.

PURPOSE: To evaluate the quantitative (cephalometric) aspects of the craniofacial deformities in transfusion-dependent beta-thalassemia (TDT) patients. MATERIALS AND METHODS: Sixty-five TDT patients receiving a regular blood transfusion in the Department of Pediatrics of age group 5 to 8 years (younger) and 15 years and above (older) were compared with control groups of similar age using cephalograms (lateral and posterior-anterior view). RESULTS AND OBSERVATION: The prevalence of skeletal class II tendency is higher in thalassemic patients that do not improve with age. The thalassemic patients were found to show large angle ANB i.e. Angle between points point a, nasion and point B (ANB), large flexure angle, small angle SNB i.e. Angle between points sella, nasion and point B (SNB), and normal angle SNA i.e. Angle between points sella, nasion and point A (SNA) angles suggestive of retrognathic mandible. The thalassemic patients were observed to have smaller transverse widths and thickened calvarium on the posterior-anterior view. CONCLUSION: The skeletal class II malocclusion appears to be a manifestation of generalized growth retardation/delayed puberty in thalassemic patients leading to diminished mandibular growth, rather than maxillary prognathism due to marrow hyperplasia.

Serum kallistatin as a marker of severity of liver fibrosis in cirrhosis: A cross-sectional observational study.

Background: Liver cirrhosis is among the leading causes of morbidity and mortality worldwide. Although liver biopsy is the gold standard for the assessment of liver fibrosis in cirrhosis, it has its own limitations. Therefore, noninvasive methods to detect liver fibrosis are widely preferred. However, they also have their own limitations. Thus, there is always a need to extend the battery of serum-based assays. Kallistatin is a protein synthesized primarily in the liver. As it is a negative acute-phase protein, its blood level decreases with a decline in liver function. In our study, we explored the relationship between serum kallistatin and radiological evidence of liver fibrosis by transient elastography to determine if kallistatin levels can be used as a diagnostic marker of liver fibrosis. Materials and Methods: A cross-sectional study of 1-year duration was conducted at a leading tertiary care hospital in northern India. Patients between 15 and 75 years of age having evidence of chronic liver disease were enrolled. All enrolled patients were evaluated by detailed history, physical examination, and relevant investigations. Serum kallistatin levels were quantified using the ELISA method. Grading of liver fibrosis was done using transient elastography. A FibroScan scoring card was used to convert FibroScan results measured in kPa into the Metavir scale F1-F4. Results: A total of 128 subjects, including 64 patients with cirrhosis and 64 healthy controls, were enrolled. Our study suggested that FibroScan values were significantly higher in cases as compared to controls. The kallistatin level of cases was significantly lower than that of controls. An inverse correlation was found between FibroScan value and kallistatin level among cases. Conclusion: We conclude that serum kallistatin levels are low in patients with liver fibrosis and can be used as a potential marker of liver fibrosis.

Thrombocytosis, haemorrhagic pleural effusion and fibro-infiltrative patches with cavitary lung lesions in a child with COVID-19 pneumonia.

COVID-19 infection in children is relatively mild and is associated with fewer complications compared with adults. Here we report the case of a previously healthy preteen girl who presented with active COVID-19 and shock. On day 1, ultrasound of the thorax revealed a right-sided pleural effusion with haemorrhagic pus on diagnostic tap, which improved clinically with appropriate hospital treatment. Even at discharge, the chest X-ray barely changed, indicating a fibrotic area and a collapsed lung. The patient had persistent thrombocytosis, her inflammatory markers (C reactive protein, ESR, interleukin 6, serum ferritin, D-dimer and procalcitonin) were elevated, and a high-resolution CT scan of the thorax at discharge revealed fibro-infiltrative patches with cavitary lesions in COVID-19 pneumonia, which are unusual findings. The patient was discharged on clinical improvement and was doing fine on follow-up after 2 weeks.

Three dimensional changes of maxillary arch in Unilateral cleft lip and palate patients following comprehensive orthodontic treatment on digital study models.

OBJECTIVE: To compare the effects of comprehensive orthodontic treatment on palatal area, volume, inter-canine and inter-molar width in patients with Unilateral Cleft Lip and Palate (UCLP) using scanned models of the maxillary arch. DESIGN: Retrospective cohort study. SETTING: Tertiary setting. PATIENTS: Two hundred and ten plaster study models of 70 patients with Unilateral Cleft Lip and Palate (Study group SG) and Control Group (n = 70) were scanned using Maestro 3D Dental scanner. The study groupwas further divided into subgroups; Subgroup I: treated with orthodontic treatment only (non-surgical), Subgroup II: patientsmanaged with combined orthodontics and orthognathic surgery (either maxillary advancement or maxillary distraction), Subgroup A: age >14 years and Subgroup B: age <14 years. INTERVENTIONS: Comprehensive orthodontic and Orthosurgical treatment. MAIN OUTCOME MEASURES: Pre- and post-treatment scanned maxillary models of the study group were compared for palatal area and volumeand intercanine and intermolar width. The palatal dimensions of post-treatment scanned models were also compared to that of the control group. RESULTS: The Palatal area and volume, intercanine and intermolar width were significantly higher in the post-treatment as compared to pre-treatment study models (P < 0.01). The measurements ofthe maxillary arch were significantly higher in the control group compared to the post-treatment measurements of the study group. The increase in palatal area and volume was greater in Subgroup I and A compared to Subgroup II and B patients, respectively. CONCLUSION: The 3-Dimensional palatal dimensions in UCLP group improved after orthodontic treatment but were still not comparable to the normal subjects. The patients with age >14 years showed more improvement in the maxillary arch.
