Introduction: The fusion of Lumbar Spinous Processes (LSP) of adjacent vertebrae may lead to errors in determining the correct spinal level. This may result in wrong level spinal surgeries around the lumbar region. Aim: To determine the prevalence of fusion between adjacent LSP. Materials and Methods: This study was a prospective observational study done in the Department of Anatomy, Smt. B.K. Shah Medical Institute and Research Centre, Vadodara, Gujarat, India. The present study had examined the lumbar spines in 30 formalin preserved cadavers. The fusion between the LSP of adjacent vertebrae was recorded after the removal of soft tissue from L1 to S1 vertebrae. Results: The present study found the fusion between the adjacent LSP in 11 (36.67%) cadavers (08 males; 03 females). The fusion between the adjacent LSP, from L4 to S1 vertebrae, was found in 10% of cadavers and was the most common pattern. The fusion between the adjacent LSP was more common in males (53.3%) compared to females (20%). Conclusion: The occurrence of fusion between the adjacent LSP is not uncommon.

Spinous Processes

Scoliosis is a three-dimensional trunk and spinal deformity. Patient evaluation is essential for the decision-making process and determines the selection of specific and adequate treatment. The diagnosis requires a radiological evaluation that exposes patients to radiation. This exposure reaches hazardous levels when numerous, repetitive radiographic studies are required for diagnostics, monitoring, and treatment. Technological improvements in radiographic devices have significantly reduced radiation exposure, but the risk for patients remains. Optical three-dimensional surface topography (3D ST) measurement systems that use surface topography (ST) to screen, diagnose, and monitor scoliosis are safer alternatives to radiography. The study aimed to show that the combination of plain X-ray and 3D ST scans allows for an approximate presentation of the vertebral column spinous processes line in space to determine the shape of the spine’s deformity in scoliosis patients. Twelve patients diagnosed with scoliosis, aged 13.1 ± 4.5 years (range: 9 to 20 years) (mean: Cobb angle 17.8°, SD: ±9.5°) were enrolled in the study. Patients were diagnosed using full-spine X-ray and whole torso 3D ST. The novel three-dimensional assessment of the spinous process lines by merging 3D ST and X-ray data in patients with scoliosis was implemented. The method’s expected uncertainty is less than 5 mm, which is better than the norm for a standard measurement tool. The presented accuracy level is considered adequate; the proposed solution is accurate enough to monitor the changes in the shape of scoliosis’s spinous processes line. The proposed method allows for a relatively precise calculation of the spinous process lines based on a three-dimensional point cloud obtained with a four-directional, three-dimensional structured light diagnostic system and a single X-ray image. The method may help reduce patients’ total radiation exposure and avoid one X-ray in the sagittal projection if biplanar radiograms are required for reconstructing the three-dimensional line of the spinous processes line.

BACKGROUND Myopia is a complex trait including both genetic and environmental factors as well as gene-environment interactions. It has been recognized as a risk factor for development of glaucoma. Both Myopia and raised IOP are known to increase mechanical stress at optic nerve head leading to glaucomatous nerve damage. This study intends to evaluate the clinical profile of myopic subjects and its correlation with Primary open angle glaucoma (POAG). METHODS A prospective observational study done from November 2019 to December 2020 after taking proper informed consent and ethical clearance. 164 eyes of 96 patients studied were divided into three groups, Group 1: low myopia (< -3.00D), Group 2: moderate myopia (-3.00 D to -5.75 D), Group 3: high myopia (≥ -6.00 D). A complete ocular examination was performed. Intraocular pressure was measured using Goldmann applanation tonometer. Visual field analysis using Humphrey automated perimetry was done in patients with suspected primary open angle glaucoma (POAG). Angle parameters and central corneal thickness (CCT) were measured using anterior segment optical coherence tomography (AS-OCT). RESULTS 164 eyes of 96 Myopic subjects were studied with no dropout during study period. Mean age was 46.05 yr. (range: 25-75 yr.). The refraction ranged from -0.50 DS to -17.00 DS. There was no statistically significant difference between Intraocular pressure (IOP), Central corneal thickness (CCT), corrected IOP and Nasal and Temporal Trabecular-iris Angle (TIA) between male and female of same age group. Mean IOP and mean CCT were found to vary significantly with age and with higher degree of myopia. Corrected IOP, Nasal and Temporal TIA increase significantly with higher degree of myopia. Cup-disc ratio (CDR) was found to be significantly higher in patients with moderate to high degree of Myopia. CONCLUSIONS Myopia is an important risk factor for development of primary open angle glaucoma, with its incidence increasing in patients with moderate to high myopia.

Introduction. Spontaneous nasal liquorrhea is a pathological condition associated with defect between nasal cavity and intracranial structures that lead to the expiration of the CSF from the nasal cavity.The objective is to evaluate the effectiveness of endoscopic endonasal approach in the CSF leak treatment.Material and methods. For the period from 2008 to 2018, 38 patients with spontaneous nasal liquorrhea were examined and treated in Pavlov First Saint Petersburg State Medical University, the clinic of neurosurgery of Kirov Medical Institute and Almazov National Medical Research Centre. All patients underwent plastic surgery of the CSF fistula by endoscopic endonasal aproach.Results. Only in 4 cases, there was a large defect, the failure of the closure of which required repeated surgical intervention in 1–2 weeks after the initial operation.Conclusion. The use of autologous tissues (muscle or fat autograft) is the method of choice for repeated surgical plastics of the cerebrospinal fluid fistula or in a large size defect (more than 5 mm).

Background: Pelvic organ prolapses (POP) is a common problem in women. The prevalence of POP increase with age. The true prevalence and risk factor for developing hydroureteronephrosis (HUN) in women with pelvic organ prolapse is still unclear due to lack of prospective studies on sufficiently large cohorts. This prospective study was done to study the prevalence of HUN in women with POP and to identify the risk factors for developing HUN.Methods: In this prospective observational study 219 patients were recruited for surgical repair for pelvic organ prolapse for 2 years.  Preoperatively, all patients had transabdominal scan to assess the uterus, adnexa and to look for Hydroureteronephrosis (HUN). Women with presence of HUN were followed postoperatively look for the resolution of HUN.Results: The prevalence of bilateral HUN was 6.85%. The mean age of women with HUN ranged from 51-69 years. Diabetes and hypertension were significant risk factor for development of HUN (OR 4.70, 95% CI -1.59-13.88 and OR 3.72, 95% CI- 1.23-11.1 respectively). There was a statistically significant correlation between chronic kidney disease and HUN. (OR 1 with 95%: CI 9.49-30.42). The correlation between stage of pelvic organ prolapse and HUN was not statistically significant (p = 0.062). There was a statistically significant correlation between the duration (2years -15 years) of POP to HUN. (OR 0.233, 95%0.13-0.419). Patients were followed up post operatively for resolution of HUN. HUN resolved in 9 women (60%) and persisted in 6 (40%).Conclusions: The prevalence of bilateral HUN in women with pelvic organ prolapse was 6.8%. Presence of hypertension, diabetes and chronic kidney disease was a risk factor for HUN. HUN resolved in 60% of women after pelvic reconstructive surgery.
