Effect of prostaglandin alone and in combination with trace minerals on the follicular and luteal dynamics, estrus response and pregnancy in sub-estrus buffaloes (Bubalus bubalis).

Sub-estrus is a condition when buffaloes do not display behavioural estrus signs, despite being in estrus and causes a delay in conception and increases the service period. The present study describes the effect of synthetic prostaglandin (PGF2α) alone and in combination with trace minerals on the follicular and corpus luteum (CL) dynamics, serum estradiol (E2) and progesterone (P4) concentration correlating estrus response and pregnancy outcome in sub-estrus buffaloes during the breeding season. A total of 50 sub-estrus buffaloes, identified through ultrasonography (USG) examination, were randomly allocated into three groups, viz. T1 (Synthetic PGF2α, Inj. Cloprostenol 500 µg, i.m, n = 17), T2 (Synthetic PGF2α + Trace mineral supplementation, Inj. Stimvet 1 mL/100 kg body weight, i.m., n = 17) and control (untreated; n = 16). Following treatment, 100% of sub-estrus buffaloes were induced estrus in the T1 and T2 groups, while only 18.75% were induced in the control. The CL diameter and serum P4 concentration were significantly lower at post-treatment, whereas the pre-ovulatory follicle (POF) size and serum E2 concentration were significantly higher in the T1 and T2 groups as compared to the control (p < .05). The buffaloes of the T2 group had a greater proportion of moderate intensities estrus than those of T1. Moreover, the proportion of buffaloes conceived in the T1 and T2 were 41.2% and 52.95%, respectively. The larger POF diameter and higher serum E2 concentration were associated with intense intensity estrus and higher conception rate (66.7%) in sub-estrus buffaloes. Similarly, CL regression rate, POF size and serum E2 concentration were relatively higher in the buffaloes conceived as compared to those not conceived. It is concluded that synthetic PGF2α in combination with trace minerals induces moderate to intense intensities estrus in a greater proportion of sub-estrus buffaloes and increases the conception rate during the breeding season. Moreover, behavioural estrus attributes correlating follicle and luteal morphometry, serum E2 and P4 concentration could be used to optimise the breeding time for augmenting the conception rate in sub-estrus buffaloes.

Culturally adapted psychosocial interventions (CaPSI) for early psychosis in a low-resource setting: study protocol for a large multi-center RCT.

BACKGROUND: Psychosis treatment guidelines recommend cognitive behaviour therapy (CBT) and family intervention (FI), for all patients with first episode psychosis (FEP), though guidance borrows heavily from literature in adults from high income countries. To our knowledge, there are few randomized controlled trials (RCTs) examining the comparative effect of these commonly endorsed psychosocial interventions in individuals with early psychosis from high-income countries and no such trials from low and middle-income countries (LMICs). The present study aims to confirm the clinical-efficacy and cost-effectiveness of delivering culturally adapted CBT (CaCBT) and culturally adapted FI (CulFI) to individuals with FEP in Pakistan. METHOD: A multi-centre, three-arm RCT of CaCBT, CulFI, and treatment as usual (TAU) for individuals with FEP (n = 390), recruited from major centres across Pakistan. Reducing overall symptoms of FEP will be the primary outcome. Additional aims will include improving patient and carer outcomes and estimating the economic impact of delivering culturally appropriate psychosocial interventions in low-resource settings. This trial will assess the clinical-efficacy and cost-effectiveness of CaCBT and CulFI compared with TAU in improving patient (positive and negative symptoms of psychosis, general psychopathology, depressive symptoms, quality of life, cognition, general functioning, and insight) and carer related outcomes (carer experience, wellbeing, illness attitudes and symptoms of depression and anxiety). CONCLUSIONS: A successful trial may inform the rapid scale up of these interventions not only in Pakistan but other low-resource settings, to improve clinical outcomes, social and occupational functioning, and quality of life in South Asian and other minority groups with FEP. TRIAL REGISTRATION: NCT05814913.

Outcome Analysis of Dual Plating in Management of Unstable Bicondylar Tibial Plateau Fracture - A Prospective Study.

INTRODUCTION: Bicondylar tibial plateau fractures account for 10-30% of tibial plateau fractures. Despite recent advancements in the management of unstable bicondylar tibial plateau fractures, the outcomes are often poor. The present study aimed to evaluate the functional outcomes and complications of internal fixation of bicondylar tibial plateau fractures with the dual plating using two incisions. MATERIALS AND METHODS: The present study included 30 patients (26 males; 4 females, mean age 35.6 years; range, 19 to 65 years) with bicondylar tibial plateau fractures who were treated with dual plating between January 2017 to August 2019. Out of 30 patients, 5 patients had Schatzker type (V) and 25 patients had Schatzker type (VI) bicondylar tibial plateau fracture. All patients were treated with dual plating using two incisions. In all patient's similar standard physical rehabilitation therapy was followed. All complications including intra and post-operative were assessed and recorded. The patients were followed-up for over 24 months. Functional outcomes were assessed with Rasmussen's functional grading system, Oxford knee score, and range of motion of knee joint. Radiological outcomes were evaluated using Rasmussen's radiological scoring system. RESULT: All fractures united with a mean time of 18 weeks. The average knee range of motion was 1.5° - 130° (range: 0° - 10° for extension lag, range: 100° -135° for flexion). Mean Rasmussen's functional grading score at the final follow-up was 26.75. All patients showed excellent or good radiographic results according to Rasmussen's radiological scoring with a mean score of 8.5 (range 6-10). The post-operative radiographs showed mean MPTA was 84.3° and the mean PPTA was 6.2°. In the present study, complications were encountered in five patients. However, there were no cases of secondary loss of reduction, failure of the implant, malunion, or non-union. CONCLUSION: The surgical treatment of bicondylar tibial plateau fractures with dual locking represents a significant treatment option and provides rigid fixation in these fractures with good functional and radiological outcomes.

Management of primary pulmonary alveolar proteinosis: A multicentric experience.

BACKGROUND: Pulmonary alveolar proteinosis (PAP) is a rare disease characterized by alveolar accumulation of surfactant material with reduced lung function and resulting hypoxemia. It is characterized by a variable clinical course, and whole lung lavage (WLL) is the standard treatment. Herein, we report our multicentric experience of management of primary PAP. MATERIALS AND METHODS: This retrospective study included patients with PAP managed at various armed forces respiratory centers from 2009 to 2019. The diagnosis of primary PAP was based on histopathologic confirmation on transbronchial lung biopsy or open lung biopsy and absence of causes of secondary PAP. We analyzed the response to WLL in these patients as well as the safety of the procedure. RESULTS: During the above-specified period, ten patients with a diagnosis of PAP were admitted to various armed forces respiratory centers. The median age of the patients was 34.5 years (range 23-59); there were nine males (90%). The mean duration (± standard deviation) of symptoms was 10.8 (±2.70) months. For management, WLL was done for eight patients with a median volume of 23.5 L (range 18-45) per patient. All the patients showed significant symptomatic response as well as improvement in physiological parameters with no major complications. The median follow-up of all patients was 18 (range 5-44) months. CONCLUSIONS: WLL is a safe, effective therapy in an experienced setting in patients with PAP and provides long-lasting benefits.

Acute Rejection of a Kidney Transplant in a Patient With Common Variable Immunodeficiency: A Case Report.

Common variable immunodeficiency is a primary immunodeficiency characterized by hypogammaglobulinemia and recurrent bacterial infections. We report a case of a 44-year-old male patient with end-stage renal disease and an established diagnosis of common variable immunodeficiency who underwent a living unrelated kidney transplant. He remained nearly infection free on maintenance immunoglobulin replacement. However, his posttransplant course was complicated by acute rejection that ultimately led to allograft loss. This case illustrates the challenge of transplantation in this patient population because of the delicate balance that must be achieved between maintaining adequate immunosuppression and minimizing the risk of infection.

Changes in posterior airway space and mandibular plane hyoid distance following mandibular advancement DO.

AIM: To study the changes in posterior airway space (PAS) and mandibular plane hyoid (MPH) distance following mandibular advancement using distraction osteogenesis (DO). SUBJECTS AND METHODS: A prospective study was conducted at a tertiary care dental center from May 2009 to May 2014. Twenty-five consecutively operated patients of mandibular hypoplasia who underwent mandibular advancement using distraction with at least 12 months follow-up were included in the study. The study group comprised 15 males and 10 females with an age range of 15-30 years (mean 22 years). Presurgical and postsurgical cephalometric changes were compared to determine the changes in PAS and MPH distance. RESULTS: The mean distraction achieved was 14.50 mm. The mean preoperative MPH was 18.88 mm and mean postoperative MPH was 13.16 mm with a resultant reduction by 32%. Mean preoperative PAS was 6.48 mm and mean postoperative PAS was 11.08 mm. Mean increase in PAS was 75%. Mean preoperative and postoperative SNB values were 75.4° and 79.52°, respectively. The results were statistically analyzed using paired "Student's t-test." CONCLUSION: From this study, it is concluded that statistically significant changes were achieved in MPH and SNB. Although change in PAS was statistically insignificant, it may have clinical applications, especially in the field of Phase II surgical management of obstructive sleep apnea.

The H1047R point mutation in p110 alpha changes the morphology of human colon HCT116 cancer cells.

The class IA phosphatidylinositol 3-kinases (PI3K) is involved in controlling changes in cell morphology, which is a highly coordinated cellular event. This event is powered by actin filament polymerization and remodeling. The gain-of-function mutations in the catalytic subunit of p110α of class IA PI3K, which occur in up to one-third of human colorectal cancers (CRCs), are capable of causing dysregulation of cell signaling and thus may result in the alteration in cell morphology and motility and in turn cause cancer metastasis. In vivo studies have demonstrated that cell lines bearing the H1047R point mutation, the most frequent cancer-specific mutation in the kinase domain of p110α, are more metastatic than cells carrying wild-type p110α. In the current study, we show that the H1047R in p110α of PI3K decreases F-actin polymerization, increases the formation of filopodia and significantly changes the cell morphology in HCT116 cancer cells. The anti-apoptotic protein B-cell lymphoma 2 (Bcl-2), which is also involved in actin polymerization and cell migration, is downregulated by the H1047R mutation in p110α. Our data suggest that the H1047R mutation in PI3K is responsible for the rearrangement of the cytoskeleton, alteration in cell morphology and enhancing cell motility, and that Bcl-2 may be involved in the H1047R mutation-mediated morphological changes and increased migratory capability.

Successful autotransplantation of a mature mesiodens to replace a traumatized maxillary central incisor.

AIM: This case describes the successful transplantation of a mature mesiodens tooth to replace a traumatized maxillary central incisor. SUMMARY: A 17-year-old male attended 1 week after a traumatic injury to his left maxillary central incisor (tooth 21). Radiographs revealed a horizontal root fracture and a poor prognosis. The tooth was atraumatically removed and replaced with a mesiodens lying in the same region. After stabilization, root canal treatment was performed and aesthetics were restored with a tooth coloured restoration. A 2-year follow-up revealed the tooth had good aesthetics and function. KEY LEARNING POINTS: A supernumerary nonfunctional tooth such as a mesiodens can be successfully used to replace a missing permanent tooth by autotransplantation. Autotransplantation has a high success rate if case selection is good, appropriate surgery is carried out and excellent hygiene is maintained. Autotransplantation should be considered as one of the most biologic techniques for replacing a missing tooth with minimal cost. Autotransplantation can be carried out even after complete root formation in the donor tooth.

Are pulmonary opacities a marker of pulmonary tuberculosis?

BACKGROUND: On most occasions treatment of pulmonary tuberculosis is started by physicians based predominantly on radiological opacities. Since these opacities may not be suggestive of active pulmonary tuberculosis and most of these opacities may even remain unchanged after complete treatment, starting treatment solely on the basis of these opacities may lead to ambiguous end points of cure. In view of this, study of misdiagnosis of radiological opacities as active pulmonary tuberculosis by physicians was undertaken in one of the respiratory centers of Armed Forces hospitals. METHODS: This was a prospective study of patients referred to our center for confirmation of active disease and institutional therapy. All patients who were diagnosed as pulmonary tuberculosis predominantly on radiological basis by physicians were evaluated for active pulmonary tuberculosis clinically, radiologically and microbiologically. Patients found to have inactive disease were followed for one year. At three monthly review, history, clinical examination, sputum AFB and chest radiographs were done. RESULTS: There were 36 patients [all males, mean age: 36.9 years (range: 22-46 years)]. The most common initial presentation was of asymptomatic persons (33.3%) reporting for routine medical examination. The commonest radiological pattern was localized reticular opacities (52.8%)On follow up, only one patient was diagnosed to have pulmonary tuberculosis. The final diagnosis was consolidation in 6, bronchiectasis in 8, pulmonary tuberculosis in 1 and localized pulmonary fibrosis in 21 patients. CONCLUSION: Diagnosing and treating tuberculosis predominantly on radiological basis is not appropriate and sputum microscopy and culture remains the cornerstone of diagnosing pulmonary tuberculosis.

Identification of FUS p.R377W in essential tremor.

BACKGROUND AND PURPOSE: Exome sequencing analysis has recently identified a nonsense mutation in fused in sarcoma (FUS) segregating with essential tremor (ET) within a large French-Canadian family. Further characterization of FUS resulted in the identification of additional mutations in ET patients; however, their pathogenicity still remains to be confirmed. The role of FUS in an independent cohort of ET patients from Canada was evaluated. METHODS: The entire coding sequence of FUS in 217 patients diagnosed with ET was analyzed and two missense variants in 219 healthy controls were genotyped by Sanger sequencing. RESULTS: Sequencing of FUS identified a previously reported non-pathogenic mutation p.G174_G175del in one ET patient and two healthy controls, and a novel p.R377W in one patient with family history of disease. This mutation is highly conserved and strongly predicted to be damaging by in silico analysis. CONCLUSION: This study has identified a novel FUS p.R377W substitution in ET patients. Additional genotyping studies in a large number of ET patients and controls are necessary to conclusively define its pathogenicity.

Pleuropulmonary paragonimiasis: mimicker of tuberculosis.

Infection caused by the lung fluke is endemic in north eastern parts of India. Paragonimus westermani and Paragonimus heterotremus are known to be endemic in eastern Indian states of Manipur and Nagaland. The infection is related to eating habits of the locals and is acquired by ingestion of raw, inadequately cooked crabs or crayfish containing encysted metacercariae which act as second intermediate hosts during the life cycle of the lung fluke. Diagnosis is generally delayed due to lack of suspicion and presentation similar to tuberculosis which is endemic in the population. We report pleuropulmonary paragonimiasis in a soldier from eastern India who presented with chest pain, haemoptysis, and eosinophilia. He gave history of consumption of raw crabs while on leave at his native village in Nagaland. Ova morphologically resembling Paragonimus heterotremus were detected in sputum and bronchoalveolar lavage specimen. Symptoms resolved with praziquantel treatment.

Low dose methylprednisolone induced bradycardia.

Methylprednisolone induced arrhythmias, especially bradycardia, are well known. Most of the available reports suggest the occurrence of these arrhythmias with high dose intravenous therapy. We, hereby report a case of low dose methylprednisolone induced bradycardia.

Gamma-aminobutyric acid (GABA)-B receptor 1 in cerebellar cortex of essential tremor.

Some reports suggest cerebellar dysfunction as the basis of essential tremor (ET). Several drugs with the action of gamma-aminobutyric acid (GABA) are known to improve ET. Autopsy studies were performed on brains from nine former patients followed at the Movement Disorders Clinic Saskatchewan, Canada, and compared with five normal control brains. We aimed to measure the concentration of GABA B receptor 1 (GBR1) in the brains of patients who had had ET and to compare them to the GABA concentration in brains of controls. Western blot was used to determine the expression of GBR1 in cerebellar cortex tissue. We found that compared to the controls, the ET brains had three different patterns of GBR1 protein concentration--two with high, four comparable, and three with marginally low levels. There was no association between the age of onset, severity or duration of tremor, the response to alcohol or other drugs and GBR1 level. Thus, we conclude that our study does not support that GBR1 is involved in ET. Further studies are needed to verify these results.

Essential tremor is not dependent upon cerebellar Purkinje cell loss.

UNLABELLED: The pathophysiology of essential tremor (ET) is unknown but recent studies report that the majority of ET cases has cerebellar Purkinje cell (PC) degeneration and its sequelae. OBJECTIVE: To perform PC counts in ET, and normal and Parkinson's disease (PD) controls to determine the relationship of PC loss to ET. METHODS: All ET cases and PD controls were followed at our clinic. Normal controls had no history of neurological disease and had normal standard neuropathological studies. The PC counts were done by a neuropathologist who was blinded to the clinical diagnosis. Three different methods were used for counting PC; section through any part of the PC, through any part of the PC nucleus, and through any part of PC nucleolus. The counts were done in five non-contiguous microscopic fields. RESULTS: 59 brains were studied. These included 12 ET, 41 PD controls, and six normal controls. The mean age at death was 82.7 in ET, 79.1 in PD, and 75.7 years in the normal controls. The mean duration of symptoms was 34 years in ET and 15.7 years in the PD cases. The mean PC counts through any part of the neuron were 64.8 in ET, 56.2 in PD, and 58.0 in normal controls. Differences were not significant. CONCLUSION: Cerebellar PC loss does not distinguish ET from controls. It is concluded that PC loss is neither a pathological basis for, nor the distinctive feature of ET.

Death-associated protein kinase 1 variation and Parkinson's disease.

BACKGROUND AND PURPOSE: Mutations of the LRRK2 gene are now recognized as major risk factors for Parkinson's disease. The Lrrk2 protein is a member of the ROCO family, which also includes Lrrk1 and Dapk1. Functional genetic variants of the DAPK1 gene (rs4877365 and rs4878104) have been previously associated with Alzheimer's disease. METHODS: Herein, we assessed the role of DAPK1 variants (rs4877365 and rs4878104) in risk of Parkinson's disease with Sequenom iPLEX genotyping, employing one Taiwanese series (391 patients with Parkinson's disease, 344 controls) and five separate Caucasian series' (combined sample size 1962 Parkinson's disease patients, 1900 controls). RESULTS: We observed no evidence of association for rs4877365 and rs4878104 and risk of Parkinson's disease in any of the individual series or in the combined Caucasian series under either an additive or recessive model. CONCLUSION: These specific DAPK1 intronic variants do not increase the risk of Parkinson's disease. However, further functional studies are required to elucidate the potential therapeutic implications with the dimerization of the Dapk1 and Lrrk2 proteins.
