Introduction: Breast cancer is the most frequent cancer among women. The CD34 immunohistochemical antigen serves as a tool in differentiating between benign and malignant breast lesions. It has been suggested that CD34 may be related to invasive potential. Aim: To evaluate the expression of the CD34 antigen in the stroma of benign and malignant breast lesions using the Immunohistochemistry (IHC) method. Materials and Methods: This cross-sectional study was conducted in the Department of Pathology in collaboration with the Department of Surgery at Sarojini Naidu Medical College, Agra, Uttar Pradesh, India over a period of 18 months (from January 2021 to June 2022), involving a total of 50 histopathologically confirmed cases of benign and malignant breast lesions. Postsurgical specimens, including biopsies and mastectomies, were fixed in 10% neutral buffered formalin. The initial diagnosis was made by Haematoxylin and Eosin (H&E)- stained tissue sections. Sections from the same block were subjected to IHC staining using a monoclonal antibody to the CD34 antigen, and the intensity of expression in stromal cells was graded from 0 to 3+ based on nuclear positivity: up to 5% stromal cells immunoreactive (grade-0), >5% and up to 25% (grade-1), >25% and up to 50% (grade-2), and > 50% (grade-3). The data was entered into Microsoft Excel 2007 and analysed using Statistical Package for Social Sciences (SPSS) statistical software version 19.0. The inferential statistics included the use of the Chi-square test. Results: Out of the total 50 cases evaluated, 25 (50%) were categorised as benign, and rest 25 (50%) were categorised as malignant lesions. Among the benign lesions, the most common lesion was fibroadenoma, accounting for 9 (36%) cases, followed by benign phyllode tumour, with 6 (24%) cases. Among malignant lesions, the most common lesion was Invasive Ductal Carcinoma (IDC), accounting for 23 (92%) cases. The intensity of CD34 expression was found to be significantly higher in benign as compared to malignant breast lesions. Out of the 25 benign breast cases, the maximum number of cases (19) showed Grade-3+ positivity, 5 cases showed Grade-2+, and 1 case showed Grade-0 positivity. However, among malignant lesions, maximum cases (23, 92%) showed Grade-0 on CD34 immunostaining. Conclusion: This study was undertaken to evaluate the CD34 expression in benign and malignant breast lesions which might be able to distinguish between the benign and malignant breast lesions. The most benign breast lesions express CD34 in the stroma, while it is almost totally lost in all malignant neoplasms. Loss of CD34 is associated with the tumour’s capacity for invasion. However, to determine its function as a therapeutic target in cases of breast cancer, additional research can also be done.

Introduction: Thoracic Paravertebral Block (TPVB) appears promising for reduction of postoperative pain in Modified Radical Mastectomy (MRM). Various combinations of local anaesthetics and adjuvants have been tried in TPVB but search for an ideal combination is still on. Aim: To evaluate analgesic efficacy of clonidine (1 μg/kg) as adjuvant with different concentrations of ropivacaine (0.35%, 0.2%) for TPVB in MRM surgery. Materials and Methods: This randomised double blind comparative clinical study was carried out in a tertiary care centre in Southern Rajasthan from January 2019 to March 2020, clinical study, 120 American Society of Anaesthesiologists (ASA) grade I, II patients aged 18-60 years female patients undergoing MRM surgery were randomised into three groups- RP, RC and LDRC to receive 0.35% Ropivacaine 19 mL, 0.35% Ropivacaine 19 ml+Clonidine (1 μg/kg) and 0.2% Ropivacaine 19 ml+Clonidine(1 μg/kg) diluted upto total 20 ml with normal saline, respectively. TPVB was performed at T4 level as single injection followed by administration of general endotracheal anaesthesia. The primary outcome measured was duration of analgesia. Secondary outcomes measured included consumption of rescue analgesic, Visual analog scale and perioperative haemodynamic parameters. Quantitative and qualitative data were analysed using Analysis of Variance (ANOVA) and Chi-square test respectively. p

Introduction: Renal Cell Carcinoma (RCC) is a group of neoplastic lesions with unique cytogenetic characteristics and histopathological features. The majority of studies till date on RCC have been focusing on tissue histology to plan neoadjuvant treatment in clinical settings. An accurate forecast of the histopathological subtype has clinical implications in management and response to newer treatment strategies. It is pertinent to preoperatively distinguish a solid renal masses histologically but, there are currently no well-established imaging criteria to classify these tumors on the basis of radiographic evaluation. Aim: To evaluate the differences in imaging characteristics of different histological subtypes of RCC by Power Doppler Ultrasound and Multi-Detector Computed Tomography (MDCT) scan. Materials and Methods: This cross-sectional study was conducted in the Department of Urology, Gauhati Medical College and Hospital, Guwahati, Assam, from March 2016 to December 2017. The study population consisted of 61 patients of RCC who were evaluated with MDCT and Doppler ultrasound prior to surgery and findings were correlated with histopathological forms of tumour. The Pearson Chi-square test and ANOVA test was used to statistically analyse the data. Results: Histopathology revealed clear cell Renal Cell Carcinoma (ccRCC), chromophobe Renal Cell Carcinoma (chRCC) and papillary Renal Cell Carcinoma (pRCC) in 52, 4 and 5 patients, respectively. Heterogenous enhancement was found in 51 cases and among these 90.4% were ccRCC. Absolute attenuation values in Corticomedullary Phase (CMP) and Nephrographic Phase (NP) for clear cell and chromophobe subtype were higher than papillary subtype, i.e., 88.04±30.40 Hounsfield Unit (HU) and 72.41±20.17 HU for clear cell, 60.75±22.54 HU and 88±16.06 HU for chromophobe; 22.40±12.52 HU and 58.00±4.41 HU for papillary subtype, respectively. Papillary RCC (pRCC) showed a unique enhancement pattern, with a low peak enhancement (average peak of 55.40 HU) and greatest enhancement during the NP. In this study population ccRCC, ChRCC RCC and pRCC had mean Resistive Index (RI) of 0.63±0.06, 0.58±0.0 and 0.67±0.11, respectively. Conclusion: Power doppler flow imaging is not useful in discriminating subtypes of RCC while multiphasic Computed Tomography (CT) imaging may be useful, particularly the phasic enhancement pattern to distinguish common RCC subtypes which may facilitate treatment planning and choosing appropriate tyrosine kinase inhibitors.

Introduction: The skin is the largest organ system in humans. Different skin diseases consist of non specific, non infectious and infectious diseases to various neoplastic lesions. Dermatological lesions are commonly encountered in all countries and it encompasses a wide spectrum, varies from country to country and various regions within a country and influenced by sex, age and associated systemic disorders, economy, literacy, racial and social customs. The clinical presentation is restricted to only a few changes such as hyperpigmentation, hypopigmentation, macules, papules, nodules and few others. However, the spectrum of histopathology of skin disorders is varied. Accurate diagnosis of skin disorders is of utmost importance as treatment is varied for different skin disorders presenting with the similar clinical lesions. Aim: To study histomorphological spectrum and distribution of skin lesions. Materials and Methods: This hospital-based cross-sectional study was conducted in Department of Pathology in collaboration with Department of Skin and Venereal Diseases, Sarojini Naidu Medical College, Agra, Uttar Pradesh, India, over a period of two years from September 2019 to August 2021. The biopsy sample taken from clinically diagnosed skin lesions sent to histology laboratory in 10% formalin. Sample was fixed in 10% neutral buffered formalin over a period of 12 to 24 hours. Paraffin wax blocks were made and 3-4 micrometer sections were taken and stained with Haematoxylin and Eosin (H&E) stain and histology was studied under microscope. Special stains such as Ziehl-Neelsen (Z-N) stain and Fite stain was done, whenever required. Data was entered in Microsoft Excel excel and descriptive data was obtained. Results: Out of total 105 cases, the maximum patients were of 21-30 years of age group 30 (28.57%) cases followed by 11-20 years of age group 25 (23.81%) cases with male and female ratio M:F=1.5:1. Out of total 105 cases, the most common site involved was trunk in 42 (40%) cases followed by upper limb in 25 (23.81%) cases. The most common skin lesions were non infectious 70 (66.67%) cases, followed by infectious disease 22 (20.95) cases. In non infectious papulosquamous diseases group found 25 (23.81%) cases followed by vesiculobullous and vesiculopustular diseases group 24 (22.86%) cases. Infectious diseases were seen in 22 (20.95%) cases, out of which bacterial diseases being most common in 19 (18.10%) cases followed by parasitic infection 2 (1.90%) cases. Conclusion: According to the findings of the present study the majority of skin lesions cases requiring biopsy in developing countries is still psoriasis in non infectious papulosquamous diseases group. Tuberculosis and leprosy in infectious diseases category were being the leading cause of morbidity.

Introduction: The granulomatous reaction is defined as a distinctive inflammatory pattern characterised by the granuloma. The term Granuloma was first coined by Virchow in 1864. The granuloma is characterised by collection of activated histiocytes, epithelioid cells and multinucleate giant cells that may or may not be rimed by lymphocytes and/or show central necrosis. The pattern of skin disease varies from one country to another and across different parts within same country. The granulomatous lesions of skin are a common and intriguing problem in developing countries. Aim: To study the histomorphological spectrum of granulomatous lesions of skin. Materials and Methods: This cross-sectional study was conducted in Department of Pathology, Sarojini Naidu Medical College, Agra, Uttar Pradesh, India, over a period of two years (from September 2018 to September 2020). All skin biopsies coming to the Department of Pathology were fixed in 10% neutral buffered formalin for duration of 12 to 24 hours. Paraffin wax blocks were made and 3-4 micrometer section were taken and stained with Haematoxylin and Eosin (H&E), showing granulomas on histology were included in the study. On H&E, stained slide, granulomas were studied for type, morphology and site. Special stains were used for further evaluations and analysis. Results: Out of total 124 cases studied, the maximum patients 34 (27.41%) were of 11-20 years age group. The epithelioid granuloma was the most common type in 76 (61.29%) cases followed by histiocytic granuloma in 24 (19.35%). The infectious granulomatous dermatoses were the most common histological type in which tuberculosis was most common followed by leprosy. Most commonly the lesions were found to involve the whole dermis in 74 (59.68%) cases, followed by upper and mid dermis in 35 (28.22%) cases. Out of 40 cases of leprosy, 17 (42.50%) cases were found Wade-Fite Stain positive. Out of total 57 cases of tuberculosis, 31 (54.38%) cases were found Acid-Fast Bacillus (AFB) positive. Conclusion: Authors concluded that major cause of granulomatous dermatoses in developing countries is still infectious, tuberculosis and leprosy being the leading causes. Histopathology is gold standard for diagnosis and categorisation of granulomatous dermatoses. Special stains are useful in cases of any dilemma

Introduction: Ovary is the most common site of neoplastic and non neoplastic lesion, can present in childhood to postmenopausal age group and remain the most lethal of all gynaecological malignancies. Tumour Protein (p53) gene mutations or deletions are most common in ovarian carcinoma. However, Wilms’ Tumour gene1 (WT1) and p16 expression are also seen in serous ovarian carcinoma. These Immunohistochemistry (IHC) markers are useful in the differential diagnosis of serous ovarian carcinomas. Aim: To study histomorphology of ovarian neoplasm along with expression of p53 and WT1 in surface epithelial tumours and to assess the prevalence of various ovarian neoplasms in different age groups. Materials and Methods: This cross-sectional study was conducted in Department of Pathology, Sarojini Naidu Medical College, Agra, Uttar Pradesh, India, over a period of two years (from September 2018-September 2020). A total of 78 ovarian specimen received in histology laboratory was studied for gross and microscopic features. The p53 and WT1 IHC expression pattern was studied in surface epithelial tumours. Statistical significance was calculated in relation to p53 and WT1 expression with histological type and grade of tumour using Chi-square test. Results: A total of 78 cases were studied, out of which benign tumours were the most common 40 (51.3%) cases, followed by malignant tumours 32 (41.0%) cases and borderline malignancy 6 (7.7%) cases. The most common benign lesions were mucinous cystadenoma 20 (50%) cases. Serous carcinomas were most common malignant tumours 19 (59.3%) cases followed by Germ Cell Tumours (GCT) 5 (15.6%) cases. All benign and borderline epithelial ovarian tumours were found p53 and WT1 negative. Out of 22 cases of malignant surface epithelial tumour, 14 (63.6%) and 12 (54.4%) were positive for p53 and WT1 respectively and all were serous carcinomas. Conclusion: Ovarian lesions present with wide spectrum of histomorphological features. The p53 and WT1 show different rates of expression and staining pattern in various epithelial ovarian carcinomas. Hence routine gross, proper histological examination and correct IHC interpretation is required for specific diagnosis.

Previously, Solitary Fibrous Tumour (SFT) was thought to originate from the pleura, a relatively rare mesenchymal neoplasm with an indolent course. Vulva is a very uncommon site of extrathoracic SFT. This is a report of a very uncommon case of vulval SFT in a 30-year-old female with complaint of a swelling over vulval region. Fine Needle Aspiration Cytology (FNAC) of the growth was attempted twice and only blood was aspirated. The swelling was excised completely. On histological examination, the sections revealed a cellular tumour of ovoid-to-fusiform spindle cells with indistinct cell borders, with haphazard arrangement or patternless pattern along with proliferation of variable sized blood vessels. The diagnosis was finalised to be a benign stromal tumour (most probably SFT), which was confirmed on immunohistochemical examination using Cluster of Differentiation 34 (CD34), CD99 and Signal Transducer and Activator of Transcription 6 (STAT6) markers.

Granular Cell Tumour (GCT) of nasal and paranasal area is an extremely rare entity, while the most common site is the tongue in oral cavity. GCT was first time described by Abrikossoff in 1926, which occurs in 3rd to 5th decades of life and most frequently involving the head and neck region. Abrikossoff in 1926, first time described GCT, to be derived from smooth muscle and gave the term myoblastomas, also known as Abrikossoff’s tumours. Schwann cell origin of GCT was demonstrated on immunohistochemistry through positive S100 protein identification. Herein, the authors report a case of GCT arising from right nasal vestibule in a 28-year-old female who presented with swelling since three months. On gross examination, the specimen revealed firm red and white pieces of tissue measuring 0.8x0.8x0.5 cm. Diagnosis was made by histopathological examination which was confirmed by PAS special stain and S100 immunohistochemistry. Author also abridged the clinical information, microscopic features, treatment and patient status after follow-up. This case is believed to be the 7th reported case of GCT as primary lesion at this location.

Myeloid sarcoma, also known as chloroma, granulocytic sarcoma, extramedullary Acute Myeloid Leukaemia (AML), myeloblastoma or extramedullary myeloid tumour, is a rare manifestation, characterised by the proliferation of immature myeloid cells, myeloblasts or monoblasts occurring as one or more tumour at an extramedullary site. It is associated with disruption of normal architecture of tissue in which it is found. Monoblastic sarcoma is a rare variant of myeloid sarcoma. Hereby, the authors report a rare case of primary monoblastic sarcoma in a 64-year-old male patient presented with complaint of swelling over right side lower cervical region. He had no history of AML. On physical examination, the swelling was over medial one-third of right clavicle measuring 6×5.8×3 cm. The swelling was excised and sent for histopathological examination, which was diagnosed as monoblastic sarcoma, and confirmed on immunohistochemistry.

Introduction: Septic complications are the most common cause of death in trauma patients who survive beyond 48 hours. Early diagnosis and treatment of infectious complications is essential to prevent life threatening complications like Systemic Inflammatory Response Syndrome (SIRS) and MultiOrgan Dysfunction Syndrome (MODS). Aim: To study the various risk factors for septic abdominal complications following laparotomy for trauma. Materials and Methods: A prospective longitudinal cohort single-center study was conducted from November 2016 to March 2018. Sixty patients above the age of 12 years, who underwent laparotomy for abdominal trauma in the Surgical Department of tertiary care hospital, were included in the study. Various patient variables were compared with postoperative septic abdominal complications like wound infection, wound dehiscence, anastomotic leak and intra-abdominal abscess. Data was analysed using Statistical Package for Social Sciences (SPSS) version 21.0. Results: In the total 60 patients (35.60±16.54), significant association was seen between wound infection and dehiscence with the time interval between trauma and surgery (p0.05). Conclusion: In trauma patients, factors like low RTS score, high ISS score, need for ICU stay and the presence of associated injuries may help the surgeons to decide in which patients to go for techniques like delayed closure of the wound, stoma instead of bowel anastomosis, etc., which may help to reduce postoperative septic complications.

Ileosigmoid Knotting is a rare cause of intestinal obstruction. It is also called as compound volvulus or double volvulus. It is caused by the wrapping of the ileum around the sigmoid colon and its mesentery or vice-versa. It is a rapidly progressive condition, leads to acute intestinal obstruction and gangrene in ileum as well as in the sigmoid colon. Early diagnosis and intervention is the key to a better outcome. Due to the rarity and unfamiliarity of this entity, diagnosis is usually made intraoperatively. Surgical removal of the gangrenous segment with either stoma formation or anastomosis is the only hope. An additional systemic search of the literature was done in PubMed, MEDLINE, ISIS, Embase, and CAS searches with the following free text keywords: ileosigmoid knotting, intestinal knotting, compound volvulus and double volvulus in English literature. Around 64 studies were identified, out of which 38 studies were selected for this article after the removal of duplicates and unrelated articles. These case series and reports were reviewed for aetiopathogenesis, presentation, diagnostic modalities, surgical interventions, and outcome. Along with this review article, there was a case report of ileosigmoid knotting in a 38-year-old male patient that presented in the surgical Emergency Department; with complaints of generalised pain and distention of abdomen for two days. Also, he had complained of not passing flatus and motion for two days. On examination, patient had generalised tenderness and bowel sounds were absent. X-ray abdomen showed dilated small and large bowel with multiple air-fluid levels. After resuscitation, an emergency exploratory laparotomy was done, and the diagnosis of ileosigmoid knotting with gangrene of both ileum and sigmoid colon was made intraoperatively. After resection of both gangrenous segment, colocolic anastomosis and double barrel ileostomy was performed. The postoperative course was uneventful, and patient was discharged on 7th postoperative day.

Morel Lavallée lesions (ML lesions) are a rare degloving type of injury occurring after blunt trauma, usually in the peritrochanteric region and resulting into a progressive subcutaneous swelling. The current case series includes three patients with a history of trauma and development of rapidly increasing fluctuant soft tissue swelling during a time period of 18 months. Though these lesions are typically described in peritrochanteric region, two cases were encountered in the knee region. ML lesions were diagnosed precisely using Ultrasound (USG) and Magnetic Resonance Imaging (MRI) modalities and were managed accordingly. Classification of these lesions is paramount to enhance patient outcome and reduce complications.

Introduction: Urothelial malignancies are one of the most prevalent carcinomas. In clinical practice, all patients undergo routine urine examination. If urine examination is used as a screening test to detect malignancies, it will indeed be of great help in early detection and initiation of treatment, leading to better patient care and disease outcome. There is a paucity of literature on detection of urothelial carcinomas based on flowcytometric urine analysers. Aim: To establish flowcytometry based screening criteria which could assist in detecting urothelial carcinomas on routine urine examination. Materials and Methods: The prospective study was conducted in the Department of Pathology, Rajiv Gandhi Super Speciality Hospital, Tahirpur, Delhi, India. All the samples which were sent for urine cytology from July 2017 to June 2018 were included in the study. The samples underwent cytological examination using Giemsa and Papanicolaou stain after being analysed in Sysmex UX 2000. The statistical analysis was performed using Microsoft Excel 2010 and SPSS statistical program (Version 24). Results: Total of 160 patients were included in the study. The male to female ratio in the present study was 5.67:1. Around 22% (35) cases turned out malignant, with 31 (88.6%) men and 4 (11.4%) women. The mean age for malignant cases was 60.2±5.2 years compared to 48.9±33.4 years for non-malignant cases. Multiple parameters were evaluated; only Red Blood Cell (RBC), White Blood Cells (WBC), Small Round Cells (SRC), and Epithelial Cells (EC) were statistically significant. Cut-off value for RBC was established at 52.9 cells/μL with high sensitivity, specificity and Negative Predictive Value (NPV); whereas WBC, SRC and epithelial cells showed increased NPV only. Conclusion: Automated urine analysers, with established cut-off values for detection of urothelial malignancies, could help in screening of the routine samples for early detection of urothelial malignancies.

Introduction: Clostridium Difficile Associated Diarrhoea (CDAD) is a significant cause of morbidity in hospitalised patients worldwide. The data on clinical epidemiology of this disease in Indian subcontinent is scarce. Aim: To evaluate the risk factors and clinical course of patients with CDAD. Materials and Methods: A cross-sectional study was planned at our tertiary care centre, All India Institute of Medical Sciences, whereby, all patients who had nosocomial diarrhea between 2010 and 2014 were included in the study. Their clinical and laboratory profile were recorded using structured questionnaire and their stool samples were subjected to ELISA for detection of toxins A and B (Premier toxins A and B). Those patients who had toxins A and B in their stool samples were diagnosed as CDAD. The clinical and laboratory profile of CDAD patients were further analysed. Results: A total of 791 patients with nosocomial diarrhea were included in this study. CDAD was diagnosed in a total of 48(6%) patients. The year wise breakdown of the positive patients is as follows: 7/135 (5.2%), 4/156 (2.6%), 5/141 (3.5%), 9/193 (4.7%) and 23/166 (13.8%), respectively. A total of 16/48 (33.3%) of CDAD cases belonged to the age group of 51-60 years. Malignancy (n=15, 31.25%) was the most common underlying pathological condition. All the patients had a history of antibiotic intake. Most common antibiotic used in the patients of CDAD was third generation cephalosporins (n=27, 56.25%). The use of clindamycin, carbapenems and colistin increased in the year 2014. Mean duration of hospital stay was 9.8 days. Diarrhoea was associated with fever in 50% of the patients while abdominal pain was seen in 39.6% of the patients. Conclusion: The control of Clostridium difficile infection suffers from the rampant use of higher antibiotics. There is a need for proper implementation of antimicrobial stewardship programmes and better hospital infection control to stop the transmission of this nagging bug.

The haematological abnormalities associated with active pulmonary tuberculosis were known to human beings since decades but Immune Thrombocytopenic Purpura (ITP) secondary to pulmonary tuberculosis have been reported only in a couple of instances. We report a 27 year-old male patient who was admitted to our hospital with fever, shortness of breath, haematuria, epistaxis and generalized petechiae. The sputum positivity for Acid Fast Bacilli (AFB) and chest X-ray reports were suggestive of active pulmonary tuberculosis in our patient. Clinical and laboratory parameters including bone marrow aspiration cytology diagnosed the case to be ITP. Patient was put on Directly Observed Treatment and Short course (DOTS) category-1 Anti-Tuberculosis Therapy (ATT) and prednisone following which thrombocytopenia was corrected and there was complete recovery of the patient without recurrence of thrombocytopenia.

Ulcerative colitis (UC) is an idiopathic autoimmune inflammatory disease of the gastrointestinal tract. Cerebral venous sinus thrombosis along with deep vein thrombosis, pulmonary embolism and arterial thrombosis have occasionally been reported as a complication in the active phase of UC being attributed to its pro-thrombotic state. This paper depicts a 38-year-old female with a history of UC in remission who developed sudden onset headache, blurring of vision and seizures. Subsequent diagnosis of cerebral venous sinus thrombosis was made with MRI venography and treated with low molecular weight heparin with complete resolution of symptoms. The highlights of this case underscore the importance of evaluating cerebral venous sinus thrombosis as a cause of acute onset neurological deterioration in a setting of inflammatory bowel disease. It also emphasizes on the hypothesis that the risk of venous thrombosis or other hypercoagulable states have no direct relationship with the disease activity or flare-up.

Cryoglobulins are monoclonal or polyclonal immunoglobulins that undergo reversible precipitation at low temperatures. Cryoglobulinemia is associated with HCV infection in more than 90% cases, the remaining 10% being called as Essential Cryoglobulinemia which is generally associated with a severe course and suboptimal response to conventional therapies. As the digital vessels are more prone to colder temperatures, hyperviscosity in those vessels can initiate local thrombosis and may manifest as ischemic ulceration and gangrene. We report here a very unusual case of HCV negative cryoglobulinemic vasculitis presenting as symmetrical peripheral gangrene of fingers and toes.

Implants have been designed to rehabilitate edentulous patients with fixed prosthesis or implant supported overdentures. Implant-supported single crowns and fixed partial dentures have become successful treatment alternatives to removable and fixed partial dentures. However, it is common to have clinical situations which make it impossible to use conventional as well as implant supported fixed partial dentures. The implant supported removable partial dentures can be a treatment modality that offers the multitude of benefits of implantbased therapy—biologic, biomechanical, social, and psychological to such patients. The aim of this article is to present a case report describing the fabrication and advantages of removable partial denture supported by teeth and implants for a patient with long edentulous span. The patient was satisfied with his dentures in terms of function and aesthetics. Regular follow-up visits over a period of three years revealed that the periodontal condition of remaining natural dentition and peri-implant conditions were stable. There was no evidence of excessive residual ridge resorption or mobility of the teeth, nor were any visible changes in the bone levels of the natural teeth or implants noted on radiographs.
