RESUMO

Aeromonas spp. is a pathogenic bacteria that potentially cause infection in farmed fish, including Catfishes. In the present study, dominant bacteria were isolated from diseased Clarias magur and tentatively named BLBM-05. Based on morphological, physiological, and biochemical features as well as 16S rRNA gene sequence and gyrB gene sequences (Gen Bank accession number: MT973994.1 and MZ398017.1), the bacteria in the isolate was found to be Aeromonas caviae. Further, the isolate was screened for five known virulence genes, namely ß-hemolysin, lafA, exu, ompA1 and ascV. Among them, three virulence genes related to pathogenicity, including aerolysin (aer), outer membrane protein (ompA1), lateral flagella (lafA), were identified in the A. caviae isolate. The median lethal dosage (LD50) of the BLBM-05 isolate for magur was determined as 1.53x106 CFU/mL. The histopathological analysis showed that the BLBM-05 isolate induced considerable histological lesions in the magur fish, including necrosis, hemolysis of erythrocytes, myolysis, hemorrhage, and desquamation in the intestinal tissue, tissue loosening, and infiltration of inflammatory cells. Drug sensitivity test showed that the isolate was susceptible to Gentamicin, Ceftazidine, Ceftrioxone, Amikacin, Tetracycline, Meropener and Oxytetracycline. The present results provide a scientific basis to identify A. caviae further, a line of treatment for magur infected by this pathogen.

RESUMO

BACKGROUND: Currently, minimally invasive approach is preferred for the treatment of ventral hernias. After the introduction of extended view totally extraperitoneal (e-TEP) technique, there has been a constant debate over the choice of better approach. In this study, we compare the short-term outcomes of e-TEP and laparoscopic IPOM Plus repair for ventral hernias. METHODS: This is a comparative, prospective single-center study done at GEM Hospital and research center Coimbatore, India from July 2018 to July 2019. All patients who underwent elective ventral hernia surgery with defect size of 2 to 6 cm were included. Patient demographics, hernia characteristics, operative and perioperative findings, and postoperative complications were systematically recorded and analyzed. RESULTS: We evaluated 92 cases (n = 92), 46 in each group. Mean age, sex, BMI, location of hernia, primary and incisional hernia, and comorbidity were comparable in both the groups. Mean defect size for IPOM Plus and e-TEP was 4 cm and 3.89 cm, respectively. Operative time was significantly higher for e-TEP, while postoperative pain (VAS), analgesic requirement, and postoperative hospital stay were significantly less as compared to IPOM Plus. However, 2 cases (4.35%) of e-TEP had recurrence but none in IPOM Plus group. CONCLUSION: e-TEP is an evolving procedure and comparable to IPOM Plus in terms of postoperative pain, analgesic requirement, cost of mesh, and length of hospital stay. More randomized controlled and multicentric studies are required with longer follow-up to validate our findings.

RESUMO

After the discovery of Gonadotropin-inhibitory hormone (GnIH) in birds in 2000, it showed different roles in different vertebrate classes and even in different species of same classes. In birds and mammals, GnIH inhibits the expression of gonadotropins during reproduction, while in fishes it exerts both inhibitory and stimulatory effect on reproduction. The current study evaluates the role of GnIH during reproduction in Labeo catla. The partial cDNA sequence of GnIHR1 and GnIHR3 receptor genes was identified by degenerate PCR. The mRNA expression analysis of GnIHRs during different reproductive phases showed that the expression of all three GnIH receptor genes is highest during spawning phase. The expression of GnIH receptors is detected in both brain and gonads except for GnIHR3 which only expressed in gonads. The in vivo experiments with GnIH antagonist, RF313 drastically reduced the expression level of reproduction related genes like LH, FSH, and GnRH at 1 h post-injection. In another experiment the surge induced by cGnIH-III peptide on gonadotropins gene expression is further increased when co-injected with LHRHa. However, co-injection of melatonin along with cGnIH-III peptide had opposite effects. These results showed that the GnIH/GnIHRs system has positive effect on reproduction in L. catla.

RESUMO

BACKGROUND: Condylar fractures are commonly associated with symphysis/parasymphysis fractures. Condylar fractures have been attributed to direct and indirect traumatic forces, the direction and magnitude of the forces, and the condylar anatomy. The chief aim of this study was to determine the association between the newly defined mandibular chin angle and the occurrence of condylar fractures. MATERIALS AND METHODS: A retrospective study was conducted to analyze two-dimensional computed tomography (2D CT) scans of patients with a history of chin trauma. The outcome was a symphysis/parasymphysis fracture with or without fracture of the mandibular condyle. The Mediff InstaRISPACS web-based platform was used to measure the chin angle. The cerebral aqueduct of Sylvius in the corresponding 2D CT midsagittal image was the standard reference plane to measure the chin angle. The SPSS Version 20 (IBM Corp, Armonk, NY) was used for data analysis. RESULTS: The sample size included 120 2D CT scans of patients with symphysis/parasymphysis fractures (60 associated with condylar fractures and 60 without condylar fractures). The mean chin angle in the group without condylar fracture was 133.35 ± 3.87°, which was approximately 15° lesser than in the condylar fracture group (mean, 148.56 ± 5.49°), and these findings were statistically significant (P < 0.05). CONCLUSION: Individuals with a high chin angle are potentially at a higher risk of sustaining associated condylar fractures.

RESUMO

Cholecystoenteric fistulas are rare complications of cholelithiasis, with cholecystogastric fistulas (CGFs) being the rarest. Recommended treatment is surgery; however, select asymptomatic patients can be managed conservatively. The population frequently involved is old age with multiple comorbidities. Open surgery comes with its added morbidities, especially in this subgroup and hence laparoscopic surgery might be beneficial. Sometimes, these fistulas can be incomplete. Here, we describe a case of incomplete CGF managed by laparoscopic cholecystectomy and omental patching along with a brief review of the literature.

RESUMO

Duodenal duplication cysts are rare congenital anomalies that generally present with abdominal pain and vomiting or may have nonspecific symptoms. Surgical excision is the recommended treatment owing to possible complications, including malignancy. However, difficult locations like the periampullary region are problematic and major surgical procedures, for example, pancreaticoduodenectomy is necessary for total resection. These have a high complication rate resulting in a poor quality of life, especially in children and young adults. Here, we describe a case of duodenal duplication cyst managed by robotic (transduodenal) excision along with a brief review of the literature.

RESUMO

BACKGROUND/AIMS: GnIH receptors (GnIHRs) belong to the family of G-protein coupled receptors (GPCRs) and play a key role in the regulation of reproduction from fishes to mammals, either by inhibiting or stimulating the expression of gonadotropins. The aim of this study was to characterize GnIH receptor (GnIHR2) from Indian Major Carp, Labeo catla and its docking and simulation with GnIH antagonist RF313. METHODS: The full length sequence of GnIHR2 was obtained with RACE PCR. The docking analysis of RF313 with GnIHR2 receptor was performed with AutoDock v. 4.2.6 and molecular dynamics (MD) simulation with GROMACS 5.0. RESULTS: In the present study, we cloned full-length cDNA (1733 bp) of GnIHR2 from the brain of L. catla. The phylogenetic analysis showed clustering of catla GnIHR2 with goldfish and zebrafish in the GPR147 group. L. catla GnIHR2 receptor comprised seven transmembrane domains and the 3D-structure was predicted by I-TASSER tool. The docking analysis revealed high binding affinity (-11.6 kcal/mol) of GnIH antagonist, RF313 towards GnIHR2 receptor. The primary bonds involved were alkyl and hydrogen bonds while the amino acids participated were proline 43, 210, 339, cysteine 214, leucine 211, serine 213 and phenylalanine 338. The MD simulation analysis of docked complex for 100 nano-seconds (ns) in the lipid membrane environment showed the stability of the complex with time. CONCLUSION: Our study showed that GnIH antagonist, RF313 interact tightly with the GnIH receptor, GnIHR2 of L. catla. To the best of our knowledge, this is the first report on computational modelling and MD simulation of GnIH receptor in fishes. This will help in functional characterization studies of GnIH/GnIHR system in vertebrates.

RESUMO

C-C chemokine receptor type 5, also known as CCR5 or CD195, is best known as a viral co-receptor that facilitates entry of HIV into cells. Evidence that CCR5 knockout mice display fewer dopamine neurons, lower striatal dopamine levels, and reduced locomotor activation compared to wild types also suggest a link between CCR5 receptors and cocaine dependence. Here, we tested the hypothesis using male Sprague-Dawley rats that cocaine-induced locomotor activation and conditioned place preference (CPP) are inhibited by a FDA-approved CCR5 antagonist (maraviroc), and that CCR5 gene expression in mesolimbic substrates is enhanced by repeated cocaine exposure. Pretreatment with maraviroc (1, 2.5, 5 mg/kg, IP) reduced hyperlocomotion induced by acute cocaine (10 mg/kg) without affecting spontaneous locomotor activity. For CPP experiments, rats conditioned with cocaine (10 mg/kg × 4 days, IP) were injected with maraviroc (1, 2.5, 5 mg/kg, IP) before each injection of cocaine. Maraviroc dose-dependently inhibited development of cocaine CPP, with a dose of 5 mg/kg producing a significant reduction. In rats treated repeatedly with cocaine (10 mg/kg × 4 days, IP), CCR5 gene expression was upregulated in the nucleus accumbens and ventral tegmental area but mRNA levels of CCR5 ligands (i.e., CCL3, CCL4 and CCL5) were not affected. Our results suggest that mesolimbic CCR5 receptors are dysregulated by cocaine exposure and, similar to CXCR4 and CCR2 receptors, influence behavioral effects related to the abuse liability of cocaine.

RESUMO

Gonadotropin-inhibitory hormone (GnIH) is an RFamide peptide, and its role in reproduction is well studied from fish to mammals, but very few reports are available about the function of GnIH during larval development. In this study, we examined the GnIH and GnIH receptors (GnIHRs) expression from embryogenesis to adult stage and tissue-specific expression in adult Catla catla using quantitative real-time (qRT) PCR. The qRT PCR analysis of GnIH mRNA during ontogenetic development showed the increasing trend from early developmental stages to the adult stage with the highest expression in 24 months fish. However, the expression of two GnIH receptors, GnIHR1 and GnIHR2 also increased from larval stages to the adults with a peak at 17 days post-hatching, while GnIHR3 showed the higher mRNA expression during embryogenesis and then decreasing gradually. Tissue distribution analysis of GnIH showed the highest mRNA expression of GnIH in the brain, followed by gonads of both the sexes. GnIHR1 and GnIHR2 were also highly expressed in the brain and gonads of both the sexes, while GnIHR3 showed the highest expression in gonads of both the sexes without any expression in the brain. These results suggest that the brain is the primary site of action for GnIH, GnIHR1 and GnIHR2, while gonads for GnIHR3.

RESUMO

Gonadotropin-inhibitory hormone (GnIH) plays an important role in reproduction by inhibiting the expression of gonadotropins in birds and mammals, but in fishes, it is ambiguous. In this study, we cloned 606 bp long cDNA of GnIH from Catla catla brain (cGnIH). The encoded preproGnIH peptide generated three putative peptides (cGnIH-I, -II, -III) of different size. Phylogenetic analysis of GnIH showed clustering of different peptide sequence with its orthologs in separate clades. The real-time PCR analysis showed the expression of cGnIH in brain, gonads, intestine, stomach, heart, gill and liver with the highest expression in the brain and gonads of both sexes. The basal GnIH mRNA expression was higher in spawning and spent phase of the male brain and spawning phase of the female brain. In testis, the expression was highest in spent phase, while in ovary the expression did not change significantly during reproductive phases. The in vivo experiment of cGnIH-III peptide exhibited the higher expression of HPG axis genes, lhb, fshb, cgnrh, kiss2 and kiss1r and serum hormone level of LH and FSH as soon as 3 h after the intramuscular delivery. These results suggest that the GnIH is positively involved in regulation of reproduction in HPG axis of C. catla.

RESUMO

BACKGROUND: Cardiovascular disease is the leading cause of mortality in type 1 diabetes mellitus (T1DM) and relates strongly to insulin resistance (IR). Lean and obese adolescents with T1DM have marked IR. Metformin improves surrogate markers of IR in T1DM, but its effect on directly measured IR and vascular health in youth with T1DM is unclear. We hypothesized that adolescents with T1DM have impaired vascular function and that metformin improves this IR and vascular dysfunction. METHODS: Adolescents with T1DM and control participants underwent magnetic resonance imaging of the ascending (AA) and descending aorta to assess pulse wave velocity, relative area change, and maximal (WSSMAX) and time-averaged (WSSTA) wall shear stress. Participants with T1DM also underwent assessment of carotid intima-media thickness by ultrasound, brachial distensibility by DynaPulse, fat and lean mass by dual-energy x-ray absorptiometry, fasting laboratories after overnight glycemic control, and insulin sensitivity by hyperinsulinemic-euglycemic clamp (glucose infusion rate/insulin). Adolescents with T1DM were randomized 1:1 to 3 months of 2000 mg metformin or placebo daily, after which baseline measures were repeated. RESULTS: Forty-eight adolescents with T1DM who were 12 to 21 years of age (40% body mass index [BMI] ≥90th percentile; 56% female) and 24 nondiabetic control participants of similar age, BMI, and sex distribution were enrolled. Adolescents with T1DM demonstrated impaired aortic health compared with control participants, including elevated AA and descending aorta pulse wave velocity, reduced AA and descending aorta relative area change, and elevated AA and descending aorta WSSMAX and WSSTA. Adolescents with T1DM in the metformin versus placebo group had improved glucose infusion rate/insulin (12.2±3.2 [mg·kg-1·min-1]/µIU/µL versus -2.4±3.6 [mg·kg-1·min-1]/µIU/µL, P=0.005; 18.6±4.8 [mg·lean kg-1·min-1]/µIU/µL versus -3.4±5.6 [mg·lean kg-1·min-1]/µIU/µL, P=0.005) and reduced weight (-0.5±0.5 kg versus 1.6±0.5 kg; P=0.004), BMI (-0.2±0.15 kg/m2 versus 0.4±0.15 kg/m2; P=0.005), and fat mass (-0.7±0.3 kg versus 0.6±0.4 kg; P=0.01). Glucose infusion rate/insulin also improved in normal-weight participants (11.8±4.4 [mg·kg-1·min-1]/µIU/µL versus -4.5±4.4 [mg·kg-1·min-1]/µIU/µL, P=0.02; 17.6±6.7 [mg·lean kg-1·min-1]/µIU/µL versus -7.0±6.7 [mg·lean kg-1·min-1]/µIU/µL, P=0.02). The metformin group had reduced AA WSSMAX (-0.3±0.4 dyne/cm2 versus 1.5±0.5 dyne/cm2; P=0.03), AA pulse wave velocity (-1.1±1.20 m/s versus 4.1±1.6 m/s; P=0.04), and far-wall diastolic carotid intima-media thickness (-0.04±0.01 mm versus -0.00±0.01 mm; P=0.049) versus placebo. CONCLUSIONS: Adolescents with T1DM demonstrate IR and impaired vascular health compared with control participants. Metformin improves IR, regardless of baseline BMI, and BMI, weight, fat mass, insulin dose, and aortic and carotid health in adolescents with T1DM. Metformin may hold promise as a cardioprotective intervention in T1DM. CLINICAL TRIAL REGISTRATION: URL: https://www.clinicaltrials.gov . Unique identifier: NCT01808690.

RESUMO

Planarians spend less time in light versus dark environments. We hypothesized that planarians withdrawn from cocaine or ethanol would spend even less time in the light than drug-naive planarians and that a benzodiazepine would inhibit this response. Planarians pretreated in cocaine or ethanol were placed at the midline of a Petri dish containing spring water that was split evenly into dark and light compartments. Planarians withdrawn from cocaine (1, 10, 100 µmol/l) or ethanol (0.01%) spent less time in the light compartment than water controls; however, this withdrawal response to cocaine (100 µmol/l) or ethanol (0.01%) was abolished by clorazepate (0-100 µmol/l). These data suggest that planarians, similar to rodents, show benzodiazepine-sensitive, anxiogenic-like responses during cocaine or alcohol withdrawal.

RESUMO

The kinetics of the ATP and dATP-mediated formation of a functionally-active RecA-ssDNA complex were examined by stopped-flow fluorescence spectroscopy, using a modified version of the RecA protein that contains a fluorescent reporter group in the ssDNA binding site. The results indicated that: i) an active RecA-ssDNA complex was formed more rapidly on dT200 than on dT50 when either ATP or dATP was provided as the nucleotide cofactor, and ii) active complex formation occurred more rapidly with dATP than with ATP on either dT50 or dT200. The dependence on both the identity of the nucleotide cofactor and the length of the ssDNA effector indicated that active complex formation occurs by a cooperative mechanism and that dATP is more effective than ATP in mediating the interactions between RecA monomers that drive this process. Interestingly, the time courses of dATP-mediated active complex formation were closely similar to those that were obtained with ATPγS, an effectively non-hydrolyzable ATP analog that strongly stabilizes the active conformation of the RecA-ssDNA complex. These results provide mechanistic insight into the enhanced ssDNA binding and DNA strand exchange activities that are observed when dATP is provided in place of ATP in RecA biochemical assays.

RESUMO

Background: The healthcare managers need to develop the managerial skills and use it for better healthcare delivery. A manager requires leadership skill to empower employees and motivate them to work in an efficient manner to achieve organizational goal. Motivating employees/subordinates and developing positive attitude toward them is one of the crucial skills that the leader needs to develop. The way health team works as a unit affects the outcome and needs good leader. With this background, the current study tends to explore the managerial skills of middle-level managers. Objectives: 1. To assess the leadership and team management skills of middle-level managers and 2. To find out motivational factors used by managers. Materials and Methods: A cross-sectional study was conducted among district-level healthcare managers and medical officers. Data collection was performed via semistructured and scale-based questionnaire and analyzed using Microsoft office excel. Results: 60% of managers had participative leadership style. Team work skills were fair enough among the managers. 53% of medical officers were freshly appointed with experience of less than one year. The middle-level managers used appreciation of work (41.8%) as major motivator of the team. Conclusions: The middle-level healthcare managers have good leadership quality as well as teamwork skills. Appreciation of work is commonly used motivator.

RESUMO

Background: Among the Indian adolescents, the prevalence of psychiatric morbidity and alcohol use disorders (AUD) are 7.3% and 1.3%. However, no separate data are available for indigenous tribal populations. This study estimated the prevalence of psychiatric morbidity and AUD and associated socio-demographic factors among adolescents in the tribal communities in three widely varying states in India. Methods: Using validated Indian versions of the MINI 6.0, MINI Kid 6.0, and ICD-10 criteria, we conducted a cross-sectional survey from January to May 2019 in three Indian sites: Valsad, Gujarat (western India); Nilgiris, Tamil Nadu (south India); and East Khasi Hills district of Meghalaya (north-east India) on 623 indigenous tribal adolescents. Results: Aggregate prevalence of any psychiatric morbidity was 15.9% (95% CI: 13.1-19.0) (males: 13.6%, 95% CI: 10.0-18.1; females: 17.9%, 95% CI: 13.9-22.6), with site-wise statistically significant differences: Gujarat: 23.8% (95% CI: 18.1-30.2), Meghalaya: 17.1% (95% CI: 12.4-22.7), Tamil Nadu: 6.2% (95% CI: 3.2-10.5). The prevalence of diagnostic groups was mood disorders 6.4% (n = 40), neurotic- and stress-related disorders 9.1% (n = 57), phobic anxiety disorder 6.3% (n = 39), AUD 2.7% (n = 17), behavioral and emotional disorders 2.7% (n = 17), and obsessive-compulsive disorder 2.2% (n = 14). These differed across the sites. Conclusion: The prevalence of psychiatric morbidity in adolescent tribals is approximately twice the national average. The most common psychiatric morbidities reported are mood (affective) disorders, neurotic- and stress-related disorders, phobic anxiety disorder, AUD, behavioral and emotional disorders, andobsessive-compulsive disorder.

RESUMO

STATEMENT OF PROBLEM: Few cephalometric analyses have been put forward to assess the treatment outcome after orthodontic treatment. However, these analyses are somewhat complicated and time consuming. The Tetragon analysis is introduced with measurement of treatment outcome as one of its objectives. PURPOSE OF STUDY: The study was undertaken to evaluate the treatment outcome by checking the skeletal and dental changes using pretreatment and post-treatment radiographs and to evaluate the efficiency of treatment in the Department of Orthodontics, College of Dental Sciences, Davangere, using the Tetragon analysis. MATERIALS AND METHODS: Records of 35 finished patients with fixed orthodontic therapy using preadjusted edgewise appliance were selected. The samples were analyzed separately for the skeletal parameters consisting of skeletal class I, II and III using Tetragon analysis. RESULTS: The post-treatment reduction of upper incisor palatal plane angle was found to be statistically significant in skeletal class I (p < 0.01) and skeletal class II patients (p < 0.05). The post-treatment increase in interincisal angle was found to be statistically significant in skeletal class I (p < 0.01) class II patients (p < 0.05). CONCLUSION: Fixed appliance therapy reduced the proclination of upper incisors and increased the interincisal angle in skeletal class I and II cases but not in skeletal class III cases. The lower incisal angulation and the maxilla-mandibular plane angle did change significantly and so were the angles of the Trigon.

RESUMO

PURPOSE: The purpose of this study was to determine the efficiency of locking plates and screw system in the treatment of mandibular fracture surgery, by comparing them with the conventional system. PATIENTS AND METHODS: A protocol for selection of patients with mandibular fractures was developed. One hundred patients were treated by locking plates and screw system and another 100 patients were treated with the conventional system. The patients were prospectively evaluated for the duration of surgery, difficulties encountered during surgery, neurologic changes, postsurgical occlusal relationship, adequacy of reduction and postsurgical complications. Data were compared for statistical significance with Chi-square test and Z-test. RESULTS: There was statistically significant difference in postoperative infection, postoperative occlusal discrepancy, postoperative plate fracture and postoperative screw loosening and mobility of the fractured fragments and also the working time between the two systems. CONCLUSION: The results of the present study are comparable with other published data and support the notion that the locking miniplate system is a valid alternative to conventional miniplates with several advantages, the only drawback being the additional working time required during adaptation of this hardware.

RESUMO

Introduction: With little evidence available in the literature, this study tries to clinically determine the efficiency and outcomes of non-surgical management of post-traumatic Zygomaticomaxillary complex (ZMC) fractures. Materials and Methods: One hundred and three patients with post-traumatic isolated ZMC fractures managed conservatively for various reasons were identified. The patients were classified based on the Zingg et al. criteria into Types A, B, and C. We evaluated the resolution of signs and symptoms of six standard parameters over 6 months-persistent pain, restriction in mouth opening, infraorbital nerve (ION) paresthesia, aesthetic deformity, infraorbital step deformity with associated tenderness on palpation, and ophthalmic status. The study variables were then statistically analyzed using Cochran's Q test with an associated confidence interval of 95%. Results: A six-month follow-up revealed persisting residual deformities for all three groups. However, Type A and Type B showed significant improvement in pain reduction, mouth opening, and infraorbital nerve (ION) paresthesia. No significant improvement was noted in any of the groups for aesthetic deformity, infraorbital step deformity, and ophthalmic status. Type C, which had comminuted fracture patterns, exhibited significant defects in all the parameters. Significant inter-variable relationship between certain paired parameters was also observed. Conclusion: The Type A group is most suited for non-surgical management. Type B with a mono-bloc fracture is a crucial group that demands broader, long-term studies to extract a proper treatment protocol. Type C with severe fracture displacement validates surgical correction.

RESUMO

Background: The complex nature of maxillofacial injuries can affect the surgical treatment outcomes and general well-being of the patient. To evaluate the efficiency of the surgical treatment, assessment of the quality of life (QOL) of the patients is of vital importance. Due to the absence of an exclusive QOL assessment tool for maxillofacial fractures, we introduce the 'Twenty-point quality of life assessment in facial trauma patients in Indian population'. The aim of this study was to assess and evaluate the QOL following surgical management of maxillofacial trauma patients based on the severity of the injury. Methods: The study consisted of 182 subjects divided into two groups of 91 each (Group A: severe facial injury and Group B: mild to moderate facial injury). The Facial Injury Severity Scale (FISS) was used to determine the severity of facial fractures and injuries. The twenty-point quality of life assessment tool includes Zone 1 (Psychosocial impact) and Zone 2 (Functional and aesthetic impact), with ten domains each to assess QOL. Results: In Zone 1, the mean scores for Group A and Group B were 38.6 and 39.26, respectively. In Zone 2, Group B (44.56) had higher mean scores compared to Group A (32.92) (p< 0.001). Group B (83.8) had higher mean scores compared to Group A (71.58) when the total of both Zone 1 and Zone 2 were taken into consideration (p<0,001). In Group A, 9 out of 91 patients had a total score of 81- 100 compared to 68 in the same range in Group B. Conclusions: Proper surgical management with adequate care to the hard and soft tissues can improve the QOL by reducing postoperative psychosocial and functional complications. Aesthetic outcomes play an important role in determining the QOL. Mild/ Moderate injuries show better QOL compared to severe maxillofacial injuries.

RESUMO

Context: Treatment options for central precocious puberty (CPP) are important for individualization of therapy. Objective: We evaluated the efficacy and safety of 6-month 45-mg leuprolide acetate (LA) depot with intramuscular administration. Methods: LA depot was administered at weeks 0 and 24 to treatment-naïve (n = 27) or previously treated (n = 18) children with CPP in a phase 3, multicenter, single-arm, open-label study (NCT03695237). Week 24 peak-stimulated luteinizing hormone (LH) suppression (<4 mIU/mL) was the primary outcome. Secondary/other outcomes included basal sex hormone suppression (girls, estradiol <20 pg/mL; boys, testosterone <30 ng/dL), suppression of physical signs, height velocity, bone age, patient/parent-reported outcomes, and adverse events. Results: All patients (age, 7.8 ± 1.27 years) received both scheduled study doses. At 24 weeks, 39/45 patients (86.7%) had LH suppressed. Six were counted as unsuppressed; 2 because of missing data, 3 with LH of 4.35-5.30 mIU/mL and 1 with LH of 21.07 mIU/mL. Through 48 weeks, LH, estradiol, and testosterone suppression was achieved in ≥86.7%, ≥97.4%, and 100%, respectively (as early as week 4 for LH and estradiol and week 12 for testosterone). Physical signs were suppressed at week 48 (girls, 90.2%; boys, 75.0%). Mean height velocity ranged 5.0 to 5.3 cm/year post-baseline in previously treated patients and declined from 10.1 to 6.5 cm/year at week 20 in treatment-naïve patients. Mean bone age advanced slower than chronological age. Patient/parent-reported outcomes remained stable. No new safety signals were identified. No adverse event led to treatment discontinuation. Conclusion: Six-month intramuscular LA depot demonstrated 48-week efficacy with a safety profile consistent with other GnRH agonist formulations.
