Calvarial Tuberculosis: Shifting Paradigm from Surgical to Conservative Approach.

Background Tuberculosis (TB) is an endemic disease in developing countries like India. However, incidence of calvarial TB is very low and it presents in varied forms posing a diagnostic dilemma and delay in management. Objective This article reports a case series of 15 patients with varied presentations of calvarial TB from a tertiary care superspeciality center of Haryana state in India. Materials and Methods Study is a retrospective analysis of 15 patients with calvarial TB treated between 2018 and 2021 in a tertiary care hospital. Clinical features, radiological findings, surgical and medical management, and outcomes were reviewed. Results Of the 15 patients, 9 were males and age ranged between 12 and 45 years. Mean duration of symptoms was 2.9 months (range 1-5 months). The most common presenting symptoms were scalp swelling, discharging sinus, and pain. Four patients were treatment defaulters of pulmonary TB and two patients were found human immunodeficiency virus positive. Brain imaging showed peripherally enhancing extradural collection with bone erosions in most cases. Eleven patients were managed conservatively with fine-needle aspiration cytology (FNAC) or local debridement/sinus excision. Four patients were managed surgically with drainage of collection, excision of necrotic bone, followed by antitubercular therapy. One patient needed cerebrospinal fluid diversion for associated hydrocephalous with tubercular meningitis which could not recover and succumbed. Conclusion Calvarial TB is a rare occurrence of common prevalent diseases. Conservative management with FNAC and sinus excision followed by antitubercular treatment are the mainstay of treatment. Surgery should be reserved for extensive lesion or lesion with mass effect.

Idiopathic Granulomatous Mastitis: A Retrospective Cohort Study of Treatment Modalities in 83 Patients From Southern Thailand

Objective: Idiopathic granulomatous mastitis (IGM) is a rare condition that mimics breast cancer. Current treatment strategies include both surgical and medical therapy. This study aimed to report and describe the clinical signs, radiological findings, management, clinical course, and outcomes after treatment of IGM, from a major tertiary care institute in southern Thailand.Material and Methods: The medical records of 83 patients with IGM treated at our institute between January 2001 and April 2022 were retrospectively studied. Patient characteristics, clinical presentations, radiological findings, microbiological workups, tissue pathologies, treatment modalities, outcomes and follow-up data were reviewed and analyzed. The success rate, recurrence rate, and time to heal were compared between the different treatment modalities. Results: Overall, 83 patients were diagnosed with IGM. Due to insufficient follow-up periods, data from only 50 patients were used for the analysis. Initially, 34,3,8, and 5 were treated surgically, with steroids, anti-tuberculosis (TB) drugs, or other treatments, respectively; 32 (64%) achieved disease resolution. The median time to heal was 472 days, while the median time to heal after surgery, steroid therapy, anti-TB therapy, and others was 614.5, 333, 208.5, and 406 days, respectively. Surgery resulted in the longest time to heal; however, the difference was not statistically significant (p-value=0.23). Eighteen (36%) patients experienced recurrence.Conclusion: There was no significant difference among the treatment modalities in terms of time to heal and recurrence. Surgery resulted in the longest healing time, the highest incidence of complications, and a recurrence rate of approximately 50%. Surgical treatment should be reserved for aggressive diseases.

Management of split cord malformation and tethered cord syndrome: Experience of a main referral center in Uzbekistan

BackgroundSplit cord malformation and tethered cord syndrome are challenging pathologies in the pediatric population. During 2016–2022, 56 cases of split cord malformation (SCM) and tethered cord syndrome were treated at the Republican Specialized Scientific Medical Practical Center of Neurosurgery (RSSMPCN) of Uzbekistan. This article aims to provide a retrospective analysis of the clinical presentation, radiological findings, and surgical outcomes of patients with split cord malformation and tethered cord syndrome. MethodsThe retrospective study was conducted for 56 pediatric patients with split cord malformation and tethered cord syndrome during the abovementioned six-year period. All patients underwent MR imaging with computed tomography, followed by surgery with intraoperative neurophysiological monitoring. Each patient underwent follow-up examinations at 3 and 6 months postoperatively and yearly thereafter. ResultsThe mean patient age was 5.7 years (10 months to 15 years), and the male-to-female ratio was 1:2.2. Encouragingly, 44 (78.6 %) of the 56 patients showed improved neurological status postoperatively. Even in the cases where spur resection procedures were performed, there was partial neurological improvement, demonstrating the overall positive outcomes of the surgeries. Importantly, none of the 56 patients had neurological deteriorations in the postoperative period ConclusionsSplit cord malformation is a rare but challenging pathology of childhood. The presentation is primarily characterized by movement, sensory or bowel disorders, and back and leg pain. This underscores the importance of early recognition and intervention when neurological symptoms are evident. Surgical intervention, as demonstrated in our study, is both appropriate and efficient in improving the neurological status of the patients.

Comparative Analysis of the Clinical Manifestations of Sinonasal Natural Killer T-Cell Lymphoma and Diffuse Large B-Cell Lymphoma.

Natural killer T-cell lymphoma (NKTCL) and diffuse large B-cell lymphoma (DLBCL) are the two most prevalent subtypes of lymphoma in the sinonasal region. Accurately differentiating between sinonasal DLBCL and NKTCL is crucial for determining the appropriate treatment and prognosis. The present study compared the clinical characteristics of these two conditions. We conducted a retrospective review of 173 patients diagnosed with sinonasal lymphoma at a single institute between 2004 and 2017. This review included only patients with DLBCL and NKTCL who had more than 6 months of follow-up records. We analyzed patient data encompassing clinical characteristics, pathologic findings, radiologic findings, treatment modalities, recurrence, and survival. Among the patients analyzed, 117 patients were diagnosed with NKTCL and 45 with DLBCL. Endoscopic evaluation revealed a significantly higher incidence of crusting (p<0.001) and necrotic lesions (p=0.001) in patients with NKTCL, whereas polypoid masses were more commonly observed in patients with DLBCL (p<0.001). Computed tomography (CT) scans indicated no significant differences in bilaterality or bone destruction between the two groups. The DLBCL group exhibited a higher rate of concurrent lymph node or organ involvement than the NKTCL group (p<0.001). The 5-year overall survival rate was 67.4% for DLBCL and 69.1% for NKTCL, with no significant difference between the two. Clinical differences exist between sinonasal DLBCL and NKTCL in terms of endoscopic and CT findings. These distinct characteristics can aid in distinguishing between the two types of sinonasal lymphoma during clinical diagnosis.

Malignant Phyllodes Tumour with Heterologous Osteosarcomatous differentiation and Osteoclast-like giant cells: Case Report of an uncommon neoplasm

Background: Phyllodes tumour (PT), an uncommon fibroepithelial neoplasm accounts for less than 1% of all primary tumours of the breast. MPT with osseous differentiation often gets misdiagnosed on imaging as benign giant calcifications resulting in treatment delay. We describe a rare case of MPT with heterologous osteosarcomatous differentiation and osteoclast-like giant cells and review the literature to discuss clinical-radiological findings, differential diagnosis and treatment options. Case Presentation: A 34-year-old female presented with a right breast lump. Mammography showed a high-density irregular mass with amorphous dense calcification, suggesting neoplastic aetiology. Preoperative core needle biopsy raised the possibility of a phyllodes tumour versus giant cell tumour. Wide local excision was performed to confirm the diagnosis which revealed the presence of a biphasic tumour with osteoid-like matrix and numerous osteoclastic giant cells. Immunohistochemistry was used to rule out metaplastic carcinoma or carcinosarcoma. The stromal cells were negative for panCK and P63 and positive for vimentin, CD10 and BCL-2. The osseous component was positive for Osteonectin and SATB2. Thus, a final diagnosis of malignant phyllodes tumour with heterologous osteosarcomatous differentiation and osteoclast-like giant cells was made. Conclusion: MPT with osteosarcomatous differentiation is a rare and challenging entity associated with a poor clinical outcome. Accurate diagnosis requires a multidisciplinary approach involving breast surgeons, pathologists and radiologists with careful histopathological examination. Wide local excision with close surveillance is crucial for timely detection of tumour recurrence and metastasis.

Clinical prediction scale approach derived from a retrospective study to reduce the number of urgent, low-value cranial CT scans.

Fifty percent of cranial CT scans performed achieve no benefit and entail risks. Our aim is to determine the yield of non-traumatic urgent cranial-CT and develop a pretest clinical probability scale approach. Adult patients seen in our emergency department between 2017-2021 and referred for urgent cranial-CT for non-traumatic reasons were retrospectively recruited and randomly selected.Presenting complaint (PC), demographic variables, Relevant radiological findings (RRF) on the urgent cranial-CT and Relevant clinical-radiological findings (RCRF: admission need or RRF detection on the urgent cranial-CT or cranial CT/MRI in the following three months) were recruited. We recruited 702 patients, with median age 62 [47-76] years, 363 (51.7%) females.RCRFwere observed in 404 (57.55%); of these, 352 (50.1%) required admission. RRF were detected in 190 (27.06%): 36 acute ischemic and 27 acute hemorrhagic lesions, 115 masses, 9 edema, and 27 hydrocephalus.Predictive PC for urgent cranial-CT were motor, speech, sensory deficits, sudden alteration of mental status, epileptic seizure, cognitive impairment, neurological symptoms in cancer patients, acute headache without a prior history and with meningeal signs; nausea, vomiting, or hypertensive crisis; visual deficits, and dizziness. This algorithm provided sensitivity, specificity, positive predictive value, and negative predictive value (NPV, 95%CI in brackets) of 92.1% (89-94.5%), 27.5% (22.5-33.0%), 63.3% (59.2-67.2%), and 71.9% (62.7-80.0%), to diagnose RCRF, and 97.4% (93.4-99.1%), 21.3% (17.8-25.1%), 31.5% (27.7-35.4%), and 95.6% (90.1-98.6%), to diagnose RRF.In patients not requiring admission (n = 350), the NPV for RRF was 98.8% (93.6-100%); the negative likelihood ratio 0.08 (0.01-0.57), and sensitivity remained at 97.8% (82.2-99.9%). Applying it would have avoided performing 85/350 urgent cranial-CT (24.29%). To find one RRF, we would have gone from performing 7.8 (350/45) to 5.9 (265/45) CTs, failing to diagnose 1/45 (2.2%) RRF. This proposed clinical scale could potentially decrease 24% of urgent cranial-CT.

Acute Necrotizing Encephalopathy in Children: A Case Report in Barranquilla-Colombia

Acute necrotizing encephalopathy is a rapidly progressive disease of the central nervous system that is generally described in texts as a pathology of pediatric patients, but even in people of this age range, it is rare to find a case of this disease, which presents with a fulminant tissue necrosis and can be secondary to infections, mainly of viral origin. Due to presenting very non-specific clinical manifestations, this diagnosis often goes unnoticed or is made late. ANE survivors go through three phases during the clinical course that include the prodromal stage, the period of acute encephalopathy, and the recovery stage. It is through specific radiological findings observed on computed tomography affecting the bilateral thalamus and possibly the cerebral white matter, brainstem, or cerebellum that the diagnosis can be confirmed. This report discusses the case of an 8-year-old schoolboy who begins with acute gastroenteritis, which progresses with seizures and neurological deterioration. A skull CT scan is performed with imaging findings suggestive of acute necrotizing encephalopathy. Management is established with adequate clinical response and favorable recovery of neurological symptoms. The clinical characteristics and radiological findings are the key to facilitating an early diagnosis, reducing sequelae and improving the prognosis, which provides a chance of life to people who suffer from this condition.

Primary diffuse large B-cell lymphoma of the central nervous system identified with CSF biomarkers

BackgroundDiagnosis of primary diffuse large B-cell lymphoma of the central nervous system (PCNSL) is challenging and often delayed. MRI imaging, CSF cytology and flow cytometry have a low sensitivity and even brain biopsies can be misleading. We report three cases of PCNSL with various clinical presentation and radiological findings where the diagnosis was suggested by novel CSF biomarkers and subsequently confirmed by brain biopsy or autopsy.Case presentations.The first case is a 79-year-old man with severe neurocognitive dysfunction and static ataxia evolving over 5 months. Brain MRI revealed a nodular ventriculitis. An open brain biopsy was inconclusive. The second case is a 60-year-old woman with progressive sensory symptoms in all four limbs, evolving over 1 year. Brain and spinal MRI revealed asymmetric T2 hyperintensities of the corpus callosum, corona radiata and corticospinal tracts. The third case is a 72-year-old man recently diagnosed with primary vitreoretinal lymphoma of the right eye. A follow-up brain MRI performed 4 months after symptom onset revealed a T2 hyperintense fronto-sagittal lesion, with gadolinium uptake and perilesional edema. In all three cases, CSF flow cytometry and cytology were negative. Mutation analysis on the CSF (either by digital PCR or by next generation sequencing) identified the MYD88 L265P hotspot mutation in all three cases. A B-cell clonality study, performed in case 1 and 2, identified a monoclonal rearrangement of the immunoglobulin light chain lambda (IGL) and kappa (IGK) gene. CSF CXCL-13 and IL-10 levels were high in all three cases, and IL-10/IL-6 ratio was high in two. Diagnosis of PCNSL was later confirmed by autopsy in case 1, and by brain biopsy in case 2 and 3.ConclusionsTaken together, 5 CSF biomarkers (IL-10, IL-10/IL-6 ratio, CXCL13, MYD88 mutation and monoclonal IG gene rearrangements) were strongly indicative of a PCNSL. Using innovative CSF biomarkers can be sensitive and complementary to traditional CSF analysis and brain biopsy in the diagnosis of PCNSL, potentially allowing for earlier diagnosis and treatment.

Relationship Between History/Physical Examination and Radiological Findings with Surgical Findings to Determine the Level of Obstruction

Objective: To assess the correlation between the clinical findings and radiological findings with surgical findings in patients with intestinal obstruction and the subsequent determination of the level and severity of the obstruction. Methods: This prospective observational study was done at the general surgery department of JPMC Karachi, during 12-month from January 2022 to December 2022. Adults aged 15 years and above, clinically and radiologically suggestive of intestinal obstruction and underwent surgical intervention were included. Clinical data was collected through thorough physical examinations and detailed medical history reviews. Parameters such as abdominal pain, distension, bowel sounds, and other relevant symptoms were documented. Radiological investigations were analyzed for evidence of obstruction and its location. Patients who undergone surgical intervention, their operative findings were correlated with clinical and radiological findings. Data analysis was done by using SPSS version 26. Results: Overall, 44 patients were studied with mean age of 38.59 ± 7.77 years, 56.8% were male and 42.3% female. Common clinical findings included inability to pass gas or stool (97.7%), constipation (95.5%), dehydration (93.2%), and tachycardia (93.2%). Radiologically, air-fluid levels with valvulae connivences were most frequent (52.3%). Intra-operatively, omental bands (22.7%) were the most common finding. There was a significant association between clinical symptoms, such as tenderness and anorexia, with specific intraoperative findings (p=0.004). Radiological findings, particularly air-fluid levels, were strongly associated with surgical diagnoses (p=0.001), highlighting their importance in guiding treatment. Conclusion: Clinical assessments and abdominal X-rays in diagnosing intestinal obstruction, applicable in only a few instances. It emphasizes the superior diagnostic capability of abdominal CT scans, may enhance the surgeon's understanding of the underlying pathology.

Intracranial solitary fibrous tumors: Clinical, radiological, and histopathological insights along with review of literature

BackgroundIntracranial solitary fibrous tumors (SFTs) are rare mesenchymal neoplasms, often challenging to diagnose due to their resemblance to meningiomas and other central nervous system tumors. While advancements in molecular genetics have aided in classification, diagnostic nuances and optimal management strategies remain areas of interest. Materials and methodsThis retrospective study analyzed 11 cases of intracranial SFTs treated at a neurosurgical centre in India between February 2020 and January 2024. Clinical data, radiological findings, histopathological features, and follow-up details were reviewed. Immunohistochemistry, particularly STAT6, facilitated diagnosis confirmation. ResultsThe median age of presentation was 32 years, with a male predominance. Headache was the most common presenting symptom, often leading to misdiagnosis as meningiomas on radiological imaging. Histologically, SFTs exhibited spindle to ovoid cells with staghorn vessels and collagenized stroma, posing challenges in differential diagnosis. WHO grading predominantly revealed grade 1 tumors, though recurrence occurred, emphasizing the importance of long-term follow-up. Immunohistochemistry, particularly STAT6, played a pivotal role in distinguishing SFTs from other entities. ConclusionIntracranial SFTs present diagnostic challenges due to overlapping features with other tumors, warranting a comprehensive approach integrating clinical, radiological, and histopathological findings. Immunohistochemistry, particularly STAT6, emerges as a valuable diagnostic tool. Long-term follow-up is essential for monitoring recurrence and potential malignant transformation. Further research is needed to delineate optimal treatment strategies, including the role of radiotherapy in SFT management.

Histoplasmosis misdiagnosed as malignancies in immunocompetent and immunocompromised patients: A global perspective on clinical presentation, radiological and pathological findings

The clinical presentation of histoplasmosis is non-specific and has several mimics as documented in the literature. Regarding cancers, previous reviews emphasized mainly the clinical and radiological similarities between histoplasmosis and pulmonary malignancies. Besides lung cancers, histoplasmosis also masquerades as other malignancies. We identified one hundred and twenty-four cases of histoplasmosis clinically mistaken for malignancies. Of the 124,84 (67.7%) were included in the analyses of demographics, immune status, clinical features, diagnosis, and treatment outcomes. The remainder were excluded as the available data was mainly on diagnosis. Of the eighty-four, histoplasmosis was predominantly misdiagnosed as lung cancers (n = 16, 19.0%), gastrointestinal tumors (n = 15, 17.9%), and lymphomas/hematological malignancies (n = 15, 17.9%). Fifty-four (64.3%) were immunocompromised including 16 (29.6%) who were living with HIV, while the remainder were immunocompetent. We conclude that infective aetiologies like histoplasmosis should be considered or ruled out in patients clinically suspected of malignancy regardless of their immune status.

Autoantibodies in a Cohort of Egyptian Patients with Inflammatory Muscle Disease

Methods This descriptive observational study was conducted in Ain Shams university hospital over a period of 2 years, a total of 77 patients were recruited and 10 control samples were collected. Results A total of 34 patients tested positive for Myositis Auto-antibodies, they showed female sex predominance (61.7%), the mean values for their age and age of onset were 28.618±14.346 and 23.574±13.584 respectively. Conclusion Autoantibodies are an important tool in diagnosis and management of immune mediated myopathy, especially when paired with clinical picture, radiological and other laboratory findings, our studied sample showed higher percentage of inflammatory myopathy subtypes associated with connective tissue disorders followed by Immune medicated necrotizing myopathy subtype then anti-synthetase syndrome antibodies.

Synchronous fibrous tarsal coalition of the posterior subtalar joint and between the medial cuneiform and navicular in the same foot: An unusual case report and literature review

Tarsal coalition (TC) is a well-known abnormality of the foot articulations due to failure of embryonic mesenchymal segmentation presenting with pain or deformity in orthopedic clinics. However, simultaneous TC affecting separate tarsal joints in the same foot is rare. We report a rare case of synchronous fibrous TC of the posterior subtalar joint and between the medial cuneiform and navicular bone of the right foot in a 25-year-old male and review the literature exploring such a combination. The clinical presentation and radiological findings leading to effective diagnosis and management are highlighted.

Efficacy of a Persian-Based Method of Needling on Clinical Symptoms of Patients with COVID-19: A Pilot Randomized Controlled Clinical Trial

COVID-19 is a pandemic viral infection that has become a challenge for health systems worldwide having no definite antiviral treatment yet. The aim of this study is to evaluate the effect of a Persian-based method of needling (Ghamz with needle) on the clinical symptoms of COVID-19 patients as a pilot study. We conducted a single-blind randomized controlled clinical trial involving hospitalized adult patients with confirmed SARS-CoV-2 infection (COVID-19) by rRT-PCR method using a nasal swab. Nineteen patients who met the inclusion criteria were randomly allocated to receive Ghamz with needle in the intervention group and sham treatment group. The procedure was performed in six points (three bilateral), based on traditional Persian medicine (TPM) texts, compatible with LU5, LU7, and SP6 Chinese points with a duration of 20 minutes, every day, till the patients were discharged from the hospital. The clinical symptoms, laboratory data, and radiological findings were evaluated before and after the interventions in both groups. The results revealed that after comparing the values of the change in the study parameters, despite the significant improvement in the dyspnea (p=0.037) and O2 saturation (p=0.044) of the Ghamz group, no statistically significant difference was observed between Ghamz and sham groups using a visual analog scale (dyspnea: MD: -3.66, 95% CI: -6.49 to 0.84 vs MD: -2.20, 95% CI: -4.60 to 0.20, p= 0.217; O2 saturation: (MD: 2.61, 95% CI: -1.97 to 14.02 vs MD:4.50, 95% CI: -0.49 to 9.49, p=0.163). The radiological findings showed a better improvement in the intervention group than in the sham treatment group. In conclusion, Ghamz with needle in the mentioned points was not effective significantly in relieve the symptoms of the patients with COVID-19. However, further studies with larger samples are recommended.

Minimum 10-year follow-up outcomes of arthroscopic Bankart's repair with metallic anchors: Reliable results with low redislocation rates.

With stiff competition from alternative albeit more expensive counterparts, it has become important to establish the applicability of metallic anchors for shoulder instability in the modern era. This can be accomplished, in part, by analysing long-term outcomes. To analyse minimum 10-year outcomes from 30 patients following arthroscopic anterior stabilisation using metallic anchors. Prospectively collected data from arthroscopic Bankart repairs performed using metal anchors during 2007P-2010 were retrospectively analysed in this single-surgeon study. Comprehensive data collection included historical and clinical findings, dislocation details, operative specifics, and follow-up radiological and clinical findings including shoulder scores. The primary outcomes were patient-reported scores (Constant, American Shoulder and Elbow Surgeons [ASES], and Rowe scores) and pain and instability on a visual analogue scale (VAS). A 3% recurrence rate of dislocation was noted at the final follow-up. Total constant scores at 10 years postoperatively measured between 76 and 100 (mean 89) were significantly better than preoperative scores (mean 62.7). Congruous improvements were also noted in the Rowe and ASES scores and VAS at the 10-year review. Reliable long-term outcomes with metallic anchors in surgery for shoulder instability can be expected. Our results provide additional evidence of their continued, cost-effective presence in the modern scenario.

Screening for TSEN54 Variants in Egyptian Patients with Pontocerebellar Malformations

Introduction: Pontocerebellar hypoplasia (PCH) represents a group of rare disorders with prenatal onset and time-dependent loss of brain parenchyma, predominantly affecting the cerebellum and pons with variable involvement of supratentorial structures. Radiologically and pathologically, they are characterized by small cerebellum and pons. Our study aimed to screen for the TSEN54 gene variants in Egyptian patients with PCH for proper counseling and to describe the brain MRI and the clinical phenotype and compare, them to those described in the literature. Methods: Thirty patients from thirty Egyptian families with a diagnosis of PCH based on neuroimaging findings were selected. Clinical evaluation, radiological findings, and genetic investigations were done for all patients. Results: The common missense variant c.919G>T (p.A307S) was identified in only 6 patients from six unrelated families (6/30; 20%) who showed different degrees of pontocerebellar malformations on brain imaging. Conclusion: The presence of a dragonfly/butterfly-like pattern in the coronal section of the cerebellum recommends genetic testing of TSEN54 as a first step. For negative cases, whole-exome sequencing is essential to reach a definite diagnosis and determine the etiology.

Clinical outcome, radiological findings, and genetic features of IDH-mutant brainstem glioma in adults.

With the recent advent of genetic testing, IDH-mutant glioma has been found among adult brainstem gliomas. However, the clinical outcome and prognosis of IDH-mutant brainstem gliomas in adults have not been elucidated. This study aimed to investigate the clinical outcome, radiological findings, and genetic features of adult patients with IDH-mutant diffuse brainstem gliomas. Data from adult patients with brainstem glioma at Hokkaido University Hospital between 2006 and 2022 were retrospectively analyzed. Patient characteristics, treatment methods, genetic features, and prognosis were evaluated. Of 12 patients with brainstem glioma with proven histopathology, 4 were identified with IDH mutation. All patients underwent local radiotherapy with 54 Gray in 27 fractions combined with chemotherapy with temozolomide. Three patients had IDH1 R132H mutation and one had IDH2 R172G mutation. The median progression-free survival and overall survival were 68.4months and 85.2months, respectively, longer than that for IDH-wildtype gliomas (5.6months and 12.0months, respectively). At the time of initial onset, contrast-enhanced lesions were observed in two of the four cases in magnetic resonance imaging. As some adult brainstem gliomas have IDH mutations, and a clearly different prognosis from those with IDH-wildtype, biopsies are proactively considered to confirm the genotype.

Unusual etiology of anterior knee pain in a young athlete engaged in chronic jumping exercises: The intratendinous ganglionic cyst of the patellar tendon

Intratendinous ganglionic cysts within the patellar tendon represent an exceedingly rare pathological entity, the clinical presentation of which is poorly understood and infrequently reported. We present a comprehensive case report of a young male athlete with persistent anterior knee pain, which was ultimately attributed to the presence of an intratendinous ganglionic cyst within the patellar tendon. This report provides a detailed analysis of the clinical presentation, radiological findings, differential diagnoses, and management strategies in the context of this rare condition.

Medical management of idiopathic chylothorax in a crossbreed cat with octreotide and rutin use: A case report

BThis case report describes the diagnosis and treatment of idiopathic chylothorax in a 5-year-old female crossbreed cat who presented with respiratory distress, tachypnea, cyanosis, exercise intolerance and weight loss over a short period of time. Based on the clinical examination, blood results, radiological and echocardiographic findings, the patient was diagnosed with chylous effusion. Chylothorax was considered idiopathic because there was no underlying trauma or disease etiology. Effusion drainage was performed by thoracocentesis to reduce respiratory stress. After thoracocentesis, followed by using medical octreotide- a somatostatin analogue (Sandostatin™, 0.1 mg/ml ampoule, Novartis, USA) and rutin - a flavone benzo-γ-pyrone plant fruit extracted from the Brazilian plant Fava D'anta (Dimorphandra mollis) (Rutin - Plant-Based Bioflavonoid, 500 mg tablet, Solgar™, USA), were administered in addition to supportive treatment. Rutin and ocreotide have been used successfully in humans, dogs and cats to the treatment of pleural effusions as presented various studies. It is hoped that these drugs may also be useful for decreasing pleural effusion in cats with chylothorax. In this represented case; partial resolution of pleural effusion was observed after octreotide usage and complete resolution of pleural effusion was observed after rutin (plant-based bioflavonoid) usage. No recurrence was observed during 7 months of regular follow-up.It was determined that the use of octreotide and rutin after thoracocentesis gave successful results in the medical management of idiopathic chylothorax in cats.

Engraftment Syndrome in Autologous Hematopoietic Stem Cell Transplant Patients: Incidence, Associated Risk Factors, Features, and Outcomes.

BACKGROUND Autologous stem cell transplantation (ASCT) is the standard treatment for multiple myeloma (MM) and refractory/relapsed (R/R) lymphoma patients. Engraftment syndrome (ES) is a non-infectious febrile syndrome during ASCT. This study focused on the incidence, risk factors, manifestations, and outcomes of patients with ES receiving ASCT. MATERIAL AND METHODS This retrospective cohort study included MM and R/R lymphoma patients who underwent ASCT at Chiang Mai University Hospital from January 2014 to September 2020. ES was diagnosed by the consensus of independent reviewers based on clinical manifestations, laboratory, and radiological findings. RESULTS We included 124 patients, of whom 67 (54.1%) had lymphoma. The mean age was 48.0±12.3 years. The incidence of ES was 36.3%. The ES group had a significantly higher proportion of patients with fever, elevated liver enzymes, elevated bilirubin, hypoalbuminemia, and weight gain compared to the non-ES group. TNC more than 10×10⁸ cells/kg was an independent risk factor for ES (odds ratio 2.94 with a 95% confidence interval of 1.15-7.50, P=0.024). ES was associated with longer length of stay (22.5±8.2 vs 16.9±6.4 days, P<0.001) but was not associated with overall survival (OS). CONCLUSIONS The incidence of ES in this cohort was 36.3%. Features observed in ES patients were fever, elevated liver enzymes, elevated bilirubin, and hypoalbuminemia. TNC of more than 10×10⁸ cells/kg was an independent risk factor. ES was associated with longer length of stay but not survival outcomes.
