ABSTRACT
Background: SAMD9L is a tumor suppressor involved in regulating the proliferation and maturation of cells, particularly those derived from the bone marrow, and appears to play an important role in cerebellar function. It can be activated in hematopoietic stem cells by type I and type II interferons. It has been hypothesized to act as a critical antiviral gatekeeper regulating interferon dependent demand driven hematopoiesis. Gain of function mutations can present with an immunodeficiency due to transient severe cytopenias during viral infection. Case presentation: We report a 3-year-old boy born full term with a history of severe thrombocytopenia requiring transfusions, developmental delay, ataxia, seizure disorder, and recurrent severe respiratory viral infections. His infectious history was significant for respiratory syncytial virus with shock requiring extracorporeal membrane oxygenation complicated by cerebral infarction and a group A streptococcus empyema, osteomyelitis requiring a left below the knee amputation, and infections with rhinovirus, COVID-19, and parainfluenza requiring hospitalizations for respiratory support. Initial immunologic evaluation was done during his hospitalization for parainfluenza. His full T cell subsets was significant for lymphopenia across all cell lines with CD3 934/microL, CD4 653/microL, CD8 227/microL, CD19 76/microL, and CD1656 61/microL. His mitogen stimulation assay to phytohemagglutinin and pokeweed was normal. Immunoglobulin panel showed a mildly decreased IgM of 25 mg/dL, but normal IgA and IgG. Vaccine titers demonstrated protective titers to 12/22 pneumococcus serotypes, varicella, diphtheria, mumps, rubella, and rubeola. Repeat full T cell subsets 6 weeks later revealed marked improvement in lymphocyte counts with CD3 3083/microL, CD4 2101/microL, CD8 839/microL, CD19 225/microL, and CD1656/microL. A primary immunodeficiency genetic panel was ordered and positive for a heterozygous SAMD9L c.1549T>C (p.Trp517Arg) mutation classified as a variant of unknown significance. Discussion(s): This patient's history of severe viral infections, ataxia, thrombocytopenia, and severe transient lymphopenia during infection is suggestive of a SAM9DL gain of function mutation. Protein modeling done by the laboratory suggests this missense mutation would affect protein structure. The mutation found has been observed in individuals with thrombocytopenia. This case highlights the importance of immunophenotyping both during acute illness and once recovered.Copyright © 2023 Elsevier Inc.
ABSTRACT
Everybody in the world including the health care sector has witnessed the devastating effects of COVID- 19 infection. It is an enigma to say whether COVID -19 has gone for good or not, but has definitely presented as a challenge in itself for dental professionals. Complications have escalated especially at the end of the 2nd wave, probably due to various immunosuppressant drugs that have been used for it's aggressive treatment. These cases highlights osteomyelitis of maxilla and surrounding structures in patients due raised levels of blood sugar and also due to steroidal therapy. Recent reports that have been published, show a rate of approximately 80.76% of such cases in maxilla, out of which 61.53% patients were found to be diabetic before diagnosis. These cases presents post COVID-19 osteomyelitis which is believed to be triggered by highly raised blood sugar levels in a patient who was not a known case of diabetes mellitus.
ABSTRACT
Introduction: One of the consequences of COVID-19 is the incidence of mucormycosis in the jaws and subsequent osteomyelitis in patients with undiagnosed or uncontrolled comorbidities, such as diabetes mellitus and associated immunosuppression. Case Report: A 52-year-old male patient with a history of COVID-19 two months ago presented a painful ulcerative lesion of insidious onset in the palatal raphe measuring approximately 2 mm. He referred to numbness of the palatal region of one month of evolution. During the physical examination, purulent content, multiple pustules in the anterior maxillary buccal mucosa, and mobility of upper anterior teeth were observed. The CT revealed isodense bilateral images in maxillary and ethmoidal sinuses, bone sequestrations, and partial loss of anterior vestibular cortical bone. Laboratory tests revealed no abnormality, except for HbH1c: 10.2gr/dl. The patient was hospitalized for control of newly diagnosed diabetes mellitus. Maxillary incisional biopsy was performed, and microscopic analysis showed a mixed inflammatory infiltrate, fibrin deposits with eosinophilic and birefringent ribbon-like hyphae, branched at right angles, compatible with maxillary osteomyelitis secondary to mucormycosis. The treatment started with antifungal and intravenous antibiotics, followed by surgical cleaning under general anesthesia. The patient progressed favorably. Conclusion(s): Immunosuppression resulting from COVID-19 and/or uncontrolled systemic diseases can condition the appearance of rare opportunistic microorganisms causing infections such as mucormycosis. Early diagnosis and treatment make a difference in the morbidity and mortality of patients.
ABSTRACT
Background: Lymphoproliferation is the persistent proliferation of lymphoid cells and it's incidence in inborn errors of immunity varies from 0.7 to 18%. Material(s) and Method(s): This is a retrospective analysis of patients referred to the department of Immunology, B. J. Wadia Hospital for Children, Mumbai between March 2017 to December 2022. Inclusion criteria consisted of 3 months duration of significant lymphadenopathy and/or splenomegaly or history of lymphoma. The clinical characteristics, laboratory and molecular findings of the included patients were analyzed. Result(s): A total of 66 patients were included.

Treatment included IVIG, chemotherapy, rituximab, sirolimus, abatacept, HSCT. Conclusion(s): All children with persistent lymphoproliferation, with or without autoimmunity and/or infections should be worked up for an underlying monogenic disorder of immune dysregulation. Lymphomas presenting at abnormal site and/or age, relapse and EBV driven lymphomas require further evaluation. Presence of monogenic cause helps in providing targeted therapy.Copyright © 2023 Elsevier Inc.
ABSTRACT
Purpose. To demonstrate possibilities of multispiral computed tomography in the detection of fungal osteomyelitis in two patients with second type of diabetes mellitus two and six months after COVID-19 associated pneumonia. Material and methods. We present two clinical observations of patients with second type of diabetes mellitus who complained about pain in the upper jaw, nasal purulent discharge, difficulty in nasal breathing which appeared two and six months after COVID-19 associated pneumonia. To identify pathological changes, patients were directed to the department of radiology for the purpose of performing MSCT of the skull. Results. In the presented clinical cases, using MSCT, the features of the radiological semiotics of skull bone changes were studied in patients with fungal infection on the background of type 2 diabetes mellitus, the use of corticosteroids and after the viral COVID-19 associated pneumonia. The diagnosis was verified by histological and cytological studies of biopsy (surgical) material. Discussion. Recently, there has been an increase in the number of cases of fungal osteomyelitis of the jaws and paranasal sinuses in patients after viral pneumonia caused by SARS-CoV-2. The most common fungal infection is mucormycosis, caused by fungi belonging to the order Mucorales. The rhinocerebral form of mucormycosis is common in patients with diabetes mellitus after treatment with corticosteroids with the background of immunosuppression. This form of mucormycosis contributes to the appearance of extensive bone-destructive changes in the middle and upper zones of the maxillofacial region, requiring further surgical treatment. Conclusion. The 2019 coronavirus infection (COVID-19) caused by SARS-CoV-2 and type 2 diabetes remain urgent healthcare problems worldwide. This combination in a patient after treatment of COVID-19 associated pneumonia with corticosteroids leads to immunosuppression and the development of concomitant infections, including fungal ones. Fungal osteomyelitis in such patients, as a rule, affects the skull and is characterized by an aggressive course and requires surgical treatment. The use of modern and high-tech methods of radiation imaging, such as MSCT, allows to obtain complete diagnostic information about the localization and prevalence of the lesion, which, in the future, determines the management tactics and surgical treatment of patients of this category.Copyright © 2022 Chinese Journal of Pediatric Surgery.

ABSTRACT
OBJECTIVE: To determine the rate of different amputation levels in diabetic foot patients and the incidence of repetitive foot surgeries and evaluate the factors causing a delay in hospital stay and amputation of patients. METHODOLOGY: This prospective cohort study was conducted in Dr. Ruth K.M. Pfau, Civil Hospital Karachi, Pakistan. The study selected 375 participants from the clinic's daily patient inflow from October 2021 to March 2022 using a non-probability consecutive sampling technique. Those who had a delay in hospital stay and amputation were further followed up from May-October 2022. The chi-square test and Kruskal Wallis test (p-value <0.05) were used to correlate the effect of the level of lower limb amputation and the cause of delay in amputation using SPSS version 24.0. RESULT(S): Total 246(65.60%) were males and 129(34.40%) were females. Toe amputation was the most commonly seen amputation in 173(46.1%) participants. About 168(44.8%) patients had some in-hospital delay stay during their treatment. Preoperative hurdles (Uncontrolled RBS, Osteomyelitis, etc.) were the most common factor causing an in-hospital delay in 92(24.5%) patients. The level of amputation performed was found to be statistically significant with factors causing a delay in hospital stay through chi-square (p=0.003*) and Kruskal Wallis test H (2) statistic= 13.3, df = 3, H (2), P=0.004*). CONCLUSION(S): Diabetic foot is a frequent cause of amputation globally, majorly in developing countries like Pakistan. On-time provision of treatment to these patients can decline the global amputation rate due to diabetic foot ulcers.Copyright © 2023 Syeda Anjala Tahir.
ABSTRACT
The role of neutrophil granulocytes (NG) in the pathogenesis of COVID-19 is associated with the NG recruitment into inflammatory foci, activation of their functions and enhanced formation of neutrophil extracellular networks (NETs). In this review, we analyzed a large body of scientific literature devoted to the features of developing NETs, their role in the COVID-19 pathogenesis, a role in emerging immunothrombosis, vasculitis, acute respiratory distress syndrome, cytokine storm syndrome, and multi-organ lesions. Convincing data are presented clearly indicating about a profound role of NETs in the COVID-19 immunopathogenesis and associated severe complications resulting from intensified inflammation process, which is a key for the course of SARS-CoV-2 virus infection. The presented role of NGs and NETs, along with that of other immune system cells and pro-inflammatory cytokines, is extremely important in understanding development of overactive immune response in severe COVID-19. The scientific results obtained available now allow to identify an opportunity of regulatory effects on hyperactivated NGs, NETosis at various stages and on limiting a negative impact of pre-formed NETs on various tissues and organs. All the aforementioned data should help in creating new, specialized immunotherapy strategies designed to increase the odds of survival, reduce severity of clinical manifestations in COVID-19 patients as well as markedly reduce mortality rates. Currently, it is possible to use existing drugs, while a number of new drugs are being developed, the action of which can regulate NG quantity, positively affect NG functions and limit intensity of NETosis. Continuing research on the role of hyperactive NG and NETosis as well as understanding the mechanisms of regulating NET formation and restriction in severe COVID-19, apparently, are of high priority, because in the future the new data obtained could pave the basis for development of targeted approaches not only for immunotherapy aimed at limiting education and blocking negative effects already formed NETs in severe COVID-19, but also for immunotherapy, which could be used in combination treatment of other netopathies, primarily autoimmune diseases, auto-inflammatory syndromes, severe purulent-inflammatory processes, including bacterial sepsis and hematogenous osteomyelitis.Copyright © 2023 Saint Petersburg Pasteur Institute.

ABSTRACT
Green liver discoloration (GL) in fattening turkeys is suspected to be a multifactorial disease complex with a compromised immune system as the key factor. This study aimed to identify the formal pathogenesis of GL and to investigate possible nutritional influences. A total of 360 Bronze turkey hens out of 10 flocks from 5 fattening farms were necropsied for detection of GL during 2 consecutive trials on 2 examination dates each (70th to 75th and 120th to 127th day of fattening, respectively). At each examination date, hematological and clinical chemistry analyses, as well as determination of vitamin E and selenium concentrations in the liver, were carried out in 6 hens with (if applicable) and 6 hens without GL, representing a total of 130 individuals. Raw nutrient, energy, amino acid, bulk and trace element, and vitamin E and D3 concentrations were analyzed in feed samples for each of the five feeding phases during each trial. The results of the hematological analyses, clinical chemistry analyses, and determination of vitamin E and selenium liver concentrations were statistically evaluated between: (i) individuals with and without GL, and (ii) individuals from flocks with and without turkeys with GL. At both fattening stages, the occurrence of GL was characterized by an inflammatory reaction. A subacute inflammatory reaction was detected in the early fattening stage, indicating a viral cause of the disease. In the late fattening stage, acute inflammation indicated a bacterial cause of the disease. The results of the feed sample analyses of the different flocks were generally quite homogeneous. However, the nutrient and energy content of the feed likely contribute to GL pathogenesis.
ABSTRACT
Covid 19 infection can result in various opportunistic infections. Altered immune response, associated comorbid conditions like diabetes, prolonged steroid and broad spectrum antibiotics usage with ICU interventions lead to increased chance of such superadded infections in covid 19 patients. Here we report a case of 31 year old male with covid 19 infection who had new onset Diabetes Mellitus, developed severe acute fulminant Mucormycosis during the treatment for covid 19 infection. He presented with severe headache, nasal obstruction and discharge, bilateral ophthalmoplegia and blindness with Cavernous Sinus Thrombosis. Patient underwent aggressive surgical debridement with frontal craniectomy, maxillectomy and right orbital evisceration and left endoscopic orbital decompression and judicious efforts to revert back the immunocompromised status with high dose of Liposomal amphotericin. Post operatively patient developed right temporal lobe abscess which was drained through Endonasal Endoscopic Trans Cavernous drainage of Temporal Lobe Abscess. Patient is in 2 months follow up, with bilateral blindness and tolerating oral feeds with improved left eye ophthalmoplegia. It is imperative to note that the rising trend of mucormycosis is there in Covid 19 infections and it should be dealt with high index of suspicion in high risk patients and early aggressive treatment can save the patient as the survival rate is not high in such infections.
ABSTRACT
Mucormycosis is a fungal disease involving predominantly the paranasal sinuses and further spreading to the orbit and cerebral regions. It does rarely affect the pulmonary region and gastrointestinal regions. This disease is seen more in a very serious state, where the tissues undergo necrosis and cause huge morbidity and, in some cases, end up being fatal. The disease was common in individuals with an immune-compromised state, thus more commonly presenting in individuals with uncontrolled diabetes. The disease is usually acquired through coming into contact with spores of the fungus Mucormycetes through the nose, and the fungi invade the paranasal regions, colonize, and spread locally with angio-invasion and relying on host ferritin for survival, thereby causing tissue necrosis. The incidence of mucormycosis had increased considerably post-COVID-19 due to host immune factors. This fungus commonly spreads from paranasal regions to the cranial direction through orbit. The spread is rapid, thus needing early medical and surgical intervention. The spread of infection from the paranasal regions to the caudally placed mandible is very rarely seen. In this paper, we present three cases of mucormycosis spreading caudally and involving the mandibular regions.
ABSTRACT
COVID-19 pandemic has traumatized deep inside in minds and lives of human beings. Those who have survived are at risk of many post-COVID complications; mucormycosis being one of the most common as well as morbid infections. Mucormycosis is also known as black fungus, it is a life-threatening opportunistic fungal infection. Inoculation occurs by inhalation of spores in nose, paranasal air sinuses and in lungs. Mucormycosis is often associated in patients with compromised immunity and it presents with characteristic black necrotic eschar and necrosis. Disease affecting the facial region possess a challenge because it often disseminates with sino-orbital and cranial involvement at the time of diagnosis. Dental practice occasionally encounters unusual and subtle symptoms with non-pathognomonic clinical signs of several fatal diseases which may pretend like a common oral disease. Hence, the key knowledge to oral and primary care physicians and its precise application is necessary for the early diagnosis of such fatal infections to prevent untoward consequences in this COVID era. This article presents a case of mucormycosis with chief complaint of pain and swelling in right front tooth region, which mimicked as periodontal abscess in a patient, leading to delay in the diagnosis possess greater challenges during the treatment.
ABSTRACT
The base of skull forms the first line of barrier to be breached in the transition of rhino-orbito-palatal forms of mucormycosis to intracranial forms with various neurological deficit. The pattern of base of skull erosion has prognostic implications in overall recovery and survival of the patient. The aim of the study was to assess the pattern of skull base involvement in cases of rhino-orbital-cerebral mucormycosis (ROCM) in terms of clinical presentations, radiological findings, intraoperative illustrations and post operative recovery. This is a retrospective single centre study of Covid associated Mucormycosis (CAM) patients with skull base involvement at a tertiary referral centre of central India from May 2021 to October 2021. Amongst a total of 248 patients of CAM, 54 patients with skull base involvement were included in our study. The cases were stratified into basifrontal-BF (15%), basisphenoid-BS (20%), orbital apex-OA (15%), basiocciput-BO (26%), frontal bone osteomyelitis-FBO (22%) and sphenoid bone osteomyelitis-SBO (2%), based on their pattern of involvement of skull base and intracranial spread. Early ethmoid and cribriform plate involvement progressed to frontal lobe abscess while early maxillary disease progressed to developed temporal lobe abscess. The orbital apex lesions had early onset cavernous sinus thrombosis. Analysis of clinical manifestations and postoperative follow up revealed an emerging pattern where Posterosuperior lesions of paranasal sinuses (Ethmoid, roof of maxilla and orbit) progressing to BF, BS, OA, FBO and SBO had poorer treatment outcome than Anteroinferior (Floor of maxillary sinus, palate) based lesions which involved BO of skull base. The inferiorly located diseases had better prognosis, less duration of hospital stay, lesser mortality and decreased need for second surgery. There exists a temporal relation of the initial site of fungal load in sinonasal region to their subsequent intracranial spread. Classification into subtypes helped in disease stratification which helped in prognostication and surgical planning. Early intervention by multidisciplinary team improved survival outcome.
ABSTRACT
Introduction: Rhinomaxillary Mucormycosis (RMM) is a condition peculiarly seen as post-COVID-19 opportunistic infections with Maxillary Sinus Disease and Osteomyelitis (MSDO). The open method of debridement and closed method are two types of surgical modalities available. There is no scoring method for this infection in maxilla. This paper aims to study the clinical and CT-based outcome of open versus closed surgery of MSDO in post-COVID-19 RMM and propose a new scoring method to evaluate the disease severity, progression as well as recovery. Material and Methods: Symptomatic cases of RMM (n = 17) with a history of closed surgical treatment were enrolled for this prospective clinical study. These cases were then treated by medicinal and open surgical method. The clinical and CT scan outcomes were compared by proposed new scoring method.The CT-based score for Maxillary Sinus Disease (MSD) and Maxillary Osteomyelitis (MO) from pre-FESS (CT1), Post-FESS (Preoperative, CT2), and Post-operative (CT3) were compared for both right and left sides. One-way ANOVA test and post HOC tests were used for statistical evaluation. Conclusion: The open method of maxillary sinus surgery has given significant improvement in the treatment of RMM already treated by a closed endoscopic approach.

ABSTRACT
Introduction: Osteomyelitis is an infection of the bone that usually affects immunocompromised individuals with multiple comorbidities. Maxilla and the mandible are at risk because of close contact with primarily contaminated spaces of the oral cavity and maxillary sinus that can harbor subclinical infection and a thin mucosal layer that adheres to the periosteum. Recently, odontogenic osteomyelitis has become rare due to better oral hygiene, stomatological care, and the widespread use of antibiotics. During the pandemic of the SARS-CoV-2 virus, the availability of medical care was limited, and the number of complicated infections rose. Case report: We present two cases of odontogenic osteomyelitis of the mandible in healthy individuals that were complicated with relapses and SARS CoV-2 coinfection. The first patient was a 30-year-old otherwise healthy female who developed localized osteomyelitis after extraction of the tooth 38. She was asymptomatic but tested positive for SARS-CoV-2. The second patient was a COVID-19-positive 29-year-old male with no previous illnesses, whose odontogenic abscess and neck edema compromised the airway, requiring urgent tracheotomy. After two weeks he developed a relapse of the infection and osteomyelitis of mandibular ramus with the formation of sequestrum. Coinfection with SARS CoV-2 virus could aggravate osteomyelitis by causing immune dysfunction and depletion of CD-4 and CD-8 lymphocytes. The osteomyelitic site is hypoperfused because of tissue edema and the inability of intraosseal spaces to expand. Endothelial le-sions and increased coagulation in COVID infection could contribute to hypoperfusion and the spread of the infection. Currently, it is impossible to claim that SARS CoV-2 infection aggravated the clinical status of our patients, but further studies are needed about the impact of SARS CoV-2 infection on other organs and illnesses, especially in mild and asymptomatic cases.
ABSTRACT
Mucormycosis, a rapidly invasive form of fungal infection caused by Mucorales fungi, has high morbidity and mortality rates. Rhino-orbital-cerebral mucormycosis is the most common form of mucormycosis. With the coronavirus disease 2019 (COVID-19) outbreak, a causal correlation between mucormycosis and COVID-19 has been suspected, contributing to the abrupt increase in opportunistic fungal infection cases. We present a case of a Southeast Asian woman in her 60s with complaints of pus discharge in the palatal region with maxillary teeth mobility for 3 months. Physical examination revealed multiple nonvital upper teeth with severe mobility. Incisional biopsy of the maxilla and multidetector computed tomography of the head and neck confirmed the diagnosis of osteomyelitis of the maxilla secondary to mucormycosis. Surgical treatment was performed, and amphotericin B and posaconazole were administered. No operative complications or further bone destruction were observed at 8 months postoperatively. © 2022 China Medical Cosmetology Press Co. Ltd.
ABSTRACT
Background Information on infective endocarditis (IE) caused by the Streptococcus anginosus (S. anginosus) group is scarce. We present a case of IE with multiple splenic septic infarcts that was further complicated by renal involvement and osteomyelitis, caused by S. anginosus in a patient with diabetes. Case 58-year-old male with diabetes presented with fever and bilateral flank pain. His CT showed splenomegaly with multiple splenic infarctions and symmetric bilateral perinephric stranding indicative of nephritis. His Labs showed leukocytosis and two blood culture sets grew S.anginosus. Transesophageal echocardiogram confirmed vegetations on aortic valve (1.3 x 1.0 cm)(Image A, red arrow) and mitral valve (1.4 x 1.0 cm)(Image B, blue arrow). Lumbar spine MRI showed L2-3 vertebral osteomyelitis. [Formula presented] Decision-making Due to patient's normal oxygen saturation and clear lung auscultation and imaging, COVID-19 was ruled out. The etiology of his fever was diagnosed as S. anginosus IE, as evidenced by his vegetations and positive cultures. The patient started on IV antibiotics and IV fluids and was transferred to another facility to receive aortic and mitral bioprostheses. Conclusion This, to the best of our knowledge, is the first documented case of S. anginosus with splenic and renal involvement. The presence of multiple splenic infarcts in immunocompromised patients, in this case in someone with diabetes, should raise suspicion for the presence of vegetations and the diagnosis of S. anginosus IE.Copyright © 2023 American College of Cardiology Foundation
ABSTRACT
Objective Mycobacterium tuberculosis is an immobile aerobic bacillus that causes tuberculosis (TB) disease. We aimed to evaluate the association between coronavirus disease 2019 (COVID-19), COVID-19-related drugs, TB reactivation, and TB incidence during the pandemic. Methods Eight patients who were diagnosed as having TB in Meram Medical Faculty, Necmettin Erbakan University between March 1, 2020, and December 31, 2021, at the beginning of the pandemic, were enrolled in this study. The presence of COVID-19 infection was confirmed using COVID-19 antibody tests and the patients' COVID-19 history. We evaluated the demographic data, laboratory findings, imaging tests, and pathology results of all patients. Results We checked all our patients with TB using COVID-19 antibodies (immunoglobulin [Ig]G + IgM) or polymerase chain reaction. Seven of the eight patients were female (87.5%). The median age was 16 years. Family screening of all patients was negative, and they had bacillus Calmette-Guerin vaccine scars. Two patients had chronic diseases. One was diagnosed as having primary ciliary dyskinesia in our department (patient no. 8) and the second was under follow-up by the rheumatology department with a diagnosis of juvenile idiopathic rheumatoid arthritis. Conclusion There has been an increase in the incidence of TB in children, especially in adolescents, during the pandemic period. This may be due to the pathogenic structure of the COVID-19 virus with an unknown mechanism. In addition, lifestyle changes and changes in health care policies during the pandemic may have caused this. Further research should be performed on this topic.Copyright © 2023 Authors.

ABSTRACT
The article focuses on the clinical manifestation of inflammatory and destructive lesions of the bones of the midface, nose and paranasal sinuses as a long-term complication of COVID-19 with clinical examples provided.

The maxilla is among the jaw bones with a lot of blood flow. Maxillary bone necrosis is uncommon and can be caused by infection, trauma, or unusual metabolic abnormalities. The maxilla is a vital bone that forms the roof of the mouth cavity. Mucormycosis is a prevalent fungus that infects the maxilla, particularly in diabetic and immune-compromised people and post-COVID-19 patients. Osteomyelitis is an inflammatory condition affecting the bone and marrow tissues. It is an opportunistic infection that occurs due to the host's susceptibility to illness due to the complication of other diseases. The patient, in this case, has the chief complaint of a defect in the palate. Based on a CT brain, buccal X-Ray, and HRCT scan of Thorax. The patient's condition was diagnosed as a surgical defect in a post-operated case of mucormycotic osteomyelitis of maxilla post-COVID-19 infection. The right lower lobe's posterior segment noted a tiny soft tissue density nodule. The operated case of a surgical defect of mucormycotic osteomyelitis of maxilla post-COVID-19 infection was treated with a surgical intervention that is surgical curettage and debridement of the left maxillary sinus, bilateral fibrotomy, and reconstruction with bilateral nasolabial flap under general anesthesia. However, our objective is to enhance the quality of life, increase ventilation, increase the shoulder joint's range of motion, and enhance the joint play of the temporomandibular joint so that the patient can go back to his usual activities without difficulty. A complete pulmonary rehabilitation plan was designed to meet the patient's objectives, executed, and followed for one month. It comprised myriad interventions like bedside sitting, facial expression exercises, mouth opening exercises, neck exercises, dynamic quadriceps and hamstring, active range of motion exercises for shoulder joints, thoracic expansion exercises, and breathing exercises like diaphragmatic breathing.
