Systemic sclerosis with interstitial lung disease and myocardial infarction: a case report

Systemic sclerosis (SSc) is a rare autoimmune connective tissue disorder that causes fibrosis due to an accelerated inflammatory response. One of the most frequent co-morbidities with SSc is interstitial lung disease (ILD), which is also one of the biggest killers among SSc patients.

Case presentation

The authors present a rare case of diffuse SSc with ILD and myocardial infarction having a history of Raynaud phenomenon, skin thickening, and shortness of breath. Antinuclear antibody and antitopoisomerase antibody tests were positive. The patient was managed medically and the condition of patient is improving.

Clinical discussion

SSC can affect the skin as well as other organs, with the lungs being the most frequently involved and seriously impacted. SSc patients can have multiple organ involvement like the skin, lungs, heart, kidneys, and gastrointestinal tract. Because ILD is the leading cause of death among people with SSC, early diagnosis and high suspicion of lung involvement can reduce mortality.

Conclusion

The mortality rate for SSC associated with ILD is extremely high. Even though ILD is common in SSc, it might be difficult to identify and detect early for which a high-resolution CT scan can be used. In SSc patients, heart involvement can coexist with ILD.

Neuroendocrine Tumor Metastases to the Breast: A Case Report and Review of the Literature

Breast metastases from neuroendocrine neoplasms (NENs) are considered infrequent. We report a case of a patient with ileocecal neuroendocrine tumor (NET) metastases to both breasts, for whom the initial clinical presentation was chronic diarrhea. Breast metastasis was initially suspected by a 68-Gallium DOTANOC positron emission tomography (PET)/CT and was confirmed by histopathology. We also performed a literature review in which we identified 116 cases of NENs metastatic to the breast reported so far. Most cases occurred in older women, were caused by NETs, and had the gastrointestinal tract as the primary site.

Cervical Erector Spinae Plane Block for Giant Dermatofibrosarcoma Protuberans of Neck and Chest Wall: A Case Report

We encountered a giant dermatofibrosarcoma protuberans (DFSP) of the neck and chest wall which presented a challenge in terms of perioperative analgesia management. In recent years, erector spinae plane (ESP) block has emerged as an effective and safe analgesia technique for various surgical procedures as well as for chronic neuropathic pain without any untoward complications. A continuous lower cervical ESP block can be used successfully as an effective analgesic technique for extensive DFSP surgery involving the neck and chest wall area.

Disastrous evolution of ollier disease: a rare case report

Ollier disease is a rare genetic disorder characterized by the development of multiple enchondromas. The clinical manifestations of the disease vary widely, but patients often present with bone deformities and an increased risk of developing chondrosarcoma. Here, the authors present a case report of a 25-year-old male patient with a devastating and historic evolution of Ollier disease.

Case presentation

At the age of 10, the patient developed a sub-centimeter mass in the first phalanx of the left middle finger, which subsequently grew in size. A biopsy was performed at the age of 14, which confirmed the diagnosis of chondroma. At the age of 14, the patient developed multiple large masses on the left hand, resulting in the amputation of his left hand. At 25 years old, the patient developed new masses in his contralateral hand and left foot.

Discussion

Ollier disease is caused by somatic mutations in the PTH/PTHrP receptor gene, leading to the formation of multiple enchondromas. Patients with Ollier disease are at an increased risk of developing chondrosarcoma, which can be life-threatening. The diagnosis of Ollier disease is usually made based on clinical and radiographic findings, and genetic testing can confirm the diagnosis. Treatment is typically focused on managing the symptoms and preventing the development of chondrosarcoma.

Conclusion

The authors presented a case report of a patient with a devastating and historic evolution of Ollier disease. This case highlights the importance of early diagnosis and management of this disease to prevent the development of chondrosarcoma and minimize the risk of complications. Further research is needed to better understand the underlying mechanisms of the disease and develop effective treatments.

Two case reports of adult traumatic inferior hip dislocations following road traffic accidents without complications

Inferior dislocation of the hip is the rarest type of hip dislocation, mainly occurring from high-energy incidents, mostly from road traffic accidents or sports. It is generally an injury among adults.

Case presentation

A 17-year-old male sustained injuries as a pedestrian, and a 30-year-old male sustained a traffic accident as a motorcycle rider. Both patients complained of severe pain in the hip, decreasing range of motion, and the inability to weight bearing. In both, the affected hip joint was fixed in 90° flexion, abduction, and external rotation, and the leg was slightly shorter than the other limb. An X-ray showed the inferior dislocation of the right hip and left hip, respectively, without any sign of fracture. We reduced both dislocations closely after sedation without any complications during follow-ups.

Conclusion

This injury should be treated as an emergency, and reduction performed as soon as possible, within 6 h. It can be managed usually with closed reduction under general anesthesia. Close follow-up is necessary to prevent its complications, including avascular necrosis, associated fractures, neurovascular compromise, and articular cartilage injuries.

A Novel PSEN1 Variant Leading to Posterior Cortical Atrophy: A Case Report

We describe a 52-year-old patient with a progressive visuospatial disorder and apraxia. Neuropsychological assessment, neuroradiological findings, and Alzheimer's disease (AD) core biomarker assay on cerebrospinal fluid led to a diagnosis of posterior cortical atrophy due to AD. We performed a next generation sequencing dementia-gene panel and found the c.1301 C>T p.(Ala434Val) variant in the Presenilin1 (PSEN1) gene. The missense change affects the PAL (Pro433-Ala434-Leu435) motif critical for catalytic activity of the macromolecular γ-secretase complex. Evolutionary and integrated bioinformatic tools predicted a deleterious effect of the variant supporting its role in the AD pathogenesis.

Unveiling an oral hemangiolymphangioma

Hemangiolymphangioma is a very rare vascular malformation that develops as a combination of dilated venous and lymphatic vessels. We describe an unusual case of hemangiolymphangioma of the tongue affecting an adult man who complained of an uncomfortable, slowly progressing exophytic irregular dark red-violaceous nodular mass on his tongue that impaired speech and swallowing for two weeks. The clinical differential diagnoses were Kaposi's sarcoma and a COVID-19-related lesion. A complete blood count and serology for HIV-1 and 2 and RT-PCR for COVID-19 were requested and results were negative. An incisional biopsy was performed. Microscopically, the lesion exhibited several dilated vessels lined by normal-appearing endothelial cells, some filled with prominent intravascular erythrocytes and others containing proteinaceous eosinophilic material resembling lymphatic vessels, in close association with hyperkeratosis, papillomatosis, and acanthosis. From immunohistochemical analysis, most vessels were found to be CD34 positive, some highlighted by α-SMA, whereas D2-40 was focal. Positive staining for some lymphatic and blood vessel markers, i.e., D2-40 and CD34, respectively, indicates a mixed derivation of the lesion. HHV-8 was negative. Clinical features, the congested blood vessels with ectasia in intimate association with hyperplastic epithelium, and the immunohistochemical profile supported the final diagnosis of oral hemangiolymphangioma. The patient underwent minimally invasive surgical excision with no intercurrences. After 18 months of follow-up, there were no signs of relapse.

One-Step Robot-Assisted Complete Urinary Tract Extirpation in Man with End-Stage Renal Disease on Dialysis: The First Case Report

Urothelial carcinoma (UC) could be observed in urinary bladder (UBUC) and upper urinary tracts (UTUC). In the National Comprehensive Cancer Network guidelines for bladder cancer, extirpative surgery is indicated in certain cases. However, some extreme cases might also need the extirpation of the majority of the urinary tract, which is called complete urinary tract extirpation (CUTE). We present a patient diagnosed with high-grade UBUC and UTUC. He underwent dialysis for end-stage renal disease (ESRD) at the same time. Considering his non-functional kidneys and removing his high-risk urothelium at the same time, we performed robot-assisted CUTE to extirpate both his upper urinary tracts, urinary bladder, and prostate. In our experience, the console time was not significantly elongated, and the perioperative course was uneventful. To our knowledge, this is the first case report adopting a robotic system in such an extreme case. We conclude that robot-assisted CUTE is worth further study regarding its oncological survival outcomes and perioperative safety in patients with ESRD on dialysis.

Primary malignant melanoma of the cervix: A comprehensive analysis of case reports in the Chinese population

PURPOSE

Malignant melanoma is a tumor generated from the basal melanocytes of human epidermis. Primary malignant melanoma of the cervix (PMMC) is derived from cervical melanocytes. It is an uncommon disease, mostly occurring in perimenopausal women. PMMC has a bad prognosis and lacks a defined protocol or treatment standards. The aim of this study was to analyze the impact of different surgical procedures and different adjuvant treatment modalities on their prognosis and to find risk factors for their prognosis by integrating published case report data based on the Chinese population.

METHODS AND RESULTS

This study included 165 patients with PMMC in the Chinese population. We used the Kaplan-Meier method to build the survival curve, and the log-rank test to examine the variations among the subgroups. Prognostic factors were examined utilizing the Cox proportional hazards regression model. We found that patients who underwent radical hysterectomy-based surgery, those who underwent lymphadenectomy, and those who underwent other treatments in addition to surgery had significantly better survival rates. The overall analysis, showed that age, and FIGO Stage II, III, and IV, increased the risk of death. Moreover, radical hysterectomy (RH), total hysterectomy (TAH), lymphadenectomy, and adjuvant therapy were correlated with a decreased mortality risk.

CONCLUSION

After summarizing the current data, we recommend radical hysterectomy, and lymphadenectomy treatment for patients with PMMC. For patients who had already undergone surgery, other treatment options had a positive effect on prognosis. For patients who had already undergone surgery, other treatment options had a positive effect on prognosis; therefore patient-specific treatment options need to be further discussed.

Regenerative Endodontic Procedures in Teeth with Root Resorption: A Systematic Review

The purpose of this systematic review was to critically evaluate the available clinical literature on the use of regenerative endodontic therapy (RET) for the treatment of root resorption. All case reports, case series and clinical studies documenting the management of root resorption in mature or immature permanent teeth using RET were included. Review articles, animal studies, and RET in teeth showing developmental anomalies were excluded. A literature search was conducted in electronic databases MEDLINE, Scopus, Cochrane, and Google Scholar from 2001 to January 2022. The JBI Critical Appraisal Checklist Quality was used to appraise the included case reports and case series. The Methodological item for non-randomised studies (MINORS) tool was used to appraise the clinical study critically. After applying the inclusion and exclusion criteria, the search resulted in 14 studies (12 case reports, 1 case series, and 1 clinical study) accounting for root resorption in 34 teeth from 29 patients treated with RET. Despite the wide variation in RET protocols, the arrest of root resorption and resolution of symptoms was seen in all teeth except one (failure after 27 months). The clinical study's cone beam computed tomography (CBCT) imaging evalu- ation documented a significant volumetric decrease in resorptive and periapical lesions after RET. The clinical study was deemed as good quality using the MINORS scale. The JBI critical appraisal tool showed that the case series was of poor quality; 11 of the case reports were of good quality, while 1 case report was of fair quality. This systematic review revealed a low-to-moderate level of evidence for the use of RET in resorption cases. However, further well-designed, long-term clinical studies are required to recommend it as an alternative treatment option for root resorption management. Funding: None. The systematic review was registered in PROSPERO (CRD42021274569). (EEJ-2022-11-136).

Clinical manifestations of delayed reaction following mass hornet envenomation: a case report

Delayed reaction following mass hornet envenomation is associated with various clinical manifestations.

Case Presentation

The authors present a case of a 24-year-old male from eastern Nepal, who presented following mass envenomation by hornet stings. He had progressive yellowish discoloration of skin and sclera, myalgia, fever, and dizziness. He had passage of tea-coloured urine followed by anuria. Laboratory investigations suggested acute kidney injury, rhabdomyolysis, and acute liver injury. The authors managed the patient with supportive measures and haemodialysis. There was complete recovery of liver and renal function in the patient.

Discussion

The findings in this patient were similar to other cases reported in the literature. These patients must be managed supportively, with few requiring renal replacement therapy. Most of these patients recover completely. In low-middle-income countries like Nepal, delay in seeking care and delay in reaching care is associated with severe clinical manifestations. Delayed presentation can lead to renal shutdown and mortality; hence, early intervention is simple, and, crucial.

Conclusion

This case highlights the occurrence of delayed reaction following mass envenomation by hornets. Also, the authors show an approach to managing such patients, similar to managing any other case with acute kidney injury. In these cases, an early simple intervention can prevent mortality. It is crucial to train healthcare workers regarding toxin induced acute kidney injury and the importance of early identification and intervention.

Choice of pharmaceutical form as a key factor during ketogenic diet: a case report

West syndrome is a severe epilepsy syndrome characterised by the appearance of drug-resistant epileptic disorders associated with hypsarrhythmia and intellectual disability. Among non-pharmacological treatments, the ketogenic diet, which consists of low carbohydrate intake and a rich lipid intake, stands out. This treatment induces a state of ketosis, which has been related to a decrease in the number of seizures. It is essential to control the carbohydrate intake within drug treatment for these patients since many pharmaceutical forms, specifically liquid oral medication, may contain carbohydrates in the form of mono/polysaccharides or polyols. We describe the case report of an infant with drug-resistant West syndrome, treated with a ketogenic diet, whose antiseizure liquid medication impeded a proper response to the diet. After the substitution of these medications, the patient showed a remarkable decrease in the number of seizures.

A Catastrophic Outcome of Ineffectual Episiotomy Causing Acquired Vaginal Atresia: A Case Report

Episiotomy is an aid done to prevent perineal tears, which may involve the anal sphincter and rectum. However, if not given judiciously, this can result in an increase in morbidity in patients. We present a case report of two young females who presented to our outpatient department with a complaint of vaginismus after their previous vaginal deliveries. The first patient had partial vaginal atresia and the second patient had complete vaginal atresia after an episiotomy repair. The complication arose due to mismanaged episiotomy repair that had a severe impact on their physical, sexual, and psychological well-being. They both underwent vaginal stricture release and adhesiolysis showed satisfactory outcomes during their follow-up. Though not recommended, prophylactic episiotomy continues to be widely performed. The approach adopted during the operative delivery stays unclear, as episiotomy execution is likely to be impacted by the physician's working environment, as well as maternal and fetal circumstances. Trained execution at rural or urban and private or public facilities is the need of the hour. Counseling regarding prophylactic or emergency episiotomy and its consequences during labor should be considered as a part of their antenatal care.

Mycoplasma hominis and Ureaplasma urealyticum infections in the immediate post-lung transplant period: A case series and literature review

Mycoplasma hominis and Ureaplasma species infections in the post-transplant setting are believed to be donor-derived and can be associated with poor outcomes. Difficulty in culturing and identifying these organisms is a significant barrier to diagnosis and early intervention. Tetracyclines, macrolides and fluoroquinolones are the mainstay treatments to cure these infections; however, there are increasing reports of antibiotic resistance. In this case series, we report our single-centre experience with M. hominis and U. urealyticum infection after lung transplantation (9 recipients, all men, mean age 56 years). Delayed diagnosis was common. Young donor age (mean age 23 yrs) and high-risk donor social history (67%) were repeatedly noted in these cases, and all infections were associated with significant morbidity (anastomosis and sternal wound infection, empyema, mediastinitis, pericarditis). Two patients died; with one directly related to Ureaplasma urealyticum infection. In conclusion post lung transplant M. hominis, and U. urealyticum infections are challenging and carry high morbidity. More prospective studies are required to assess the true prevalence, full spectrum of complications and utility of molecular diagnostics to aid early diagnosis and identify antibiotic susceptibility of Mycoplasma and Ureaplasma infections in the post-lung transplant setting.

Solitary bone plasmacytoma of the tibia presenting as chronic osteomyelitis: A rare case report and literature review

RATIONALE

Plasmacytoma is a rare plasma cell dyscrasia that grows within the axial skeleton or soft tissue structures as solitary or multiple masses. The primary types are solitary plasmacytoma, including solitary bone plasmacytoma (SBP) and solitary extramedullary plasmacytoma, and multiple solitary plasmacytomas. SBP is characterized by localized proliferation of monoclonal plasma cells and is rare. However, SBP with chronic osteomyelitis is even rarer.

PATIENT CONCERNS

A 47-year-old man previously diagnosed with chronic osteomyelitis presented with repeated discharge and ulceration in the front of his right tibia.

DIAGNOSIS, INTERVENTIONS AND OUTCOMES

Lower extremity magnetic resonance imaging (MRI) and computed tomography (CT) examinations showed dead bone formation and surrounding inflammatory edema. Thus, the patient underwent dead bone excision and fenestration of the bone marrow cavity. The histopathologic examination results indicated plasmacytoma. Therefore, we administered radiotherapy with satisfactory results.

LESSONS

Physicians should pay close attention to chronic osteomyelitis because it may be accompanied by plasmacytoma. Postoperative pathological and immunohistochemical examinations are crucial, and surgical resection of the lesion and local radiotherapy are effective treatment methods.

A Rare Case of Hepatocellular Carcinoma Recurrence in Ovarian Site after 12 Years Mimicking a Hepatoid Adenocarcinoma: Case Report

Hepatoid carcinoma of the ovary (HCO) is a tumor that resembles, both histologically and cytologically, hepatocarcinoma (HCC) in a patient with a non-cirrhotic liver not involved by the disease. Hepatoid carcinoma is an extremely rare histologic subtype of ovarian cancer and should be distinguished from metastatic HCC. Here, we report the rare case of a 67-year-old woman with ovarian recurrence of HCC 12 years after first diagnosis. The patient was being followed by oncologists because she had been diagnosed with HCV-related HCC (Edmonson and Stainer grade 2, pT2 N0 M0, G2, V1) in 2009. She had undergone surgery for enlarged left hepatectomy to the 4th hepatic segment with cholecystectomy and subsequent placement of a Kehr drain. The preoperative alpha-fetoprotein (AFP) level was 8600 ng/mL, while the postoperative value was only 2.7 ng/mL. At the first diagnosis, no other localizations of the disease, including the genital tract, were found. At the time of recurrence, however, the patient was completely asymptomatic: her liver function was within normal limits with negative blood indices, except for an increased blood dosage of AFP (467 ng/mL), and CA125, which became borderline (37.4 IU/mL). The oncologist placed an indication for a thoracic abdominal CT scan, which showed that the residual liver was free of disease, and the presence of a formation with a solid-cystic appearance and some calcifications at the left adnexal site. The radiological findings were confirmed on level II gynecological ultrasound. The patient then underwent a radical surgery of hysterectomy, bilateral oophorectomy, pelvic peritonectomy, and omentectomy by a laparotomic approach, with the sending of intraoperative extemporaneous histological examination on the annexus site of the tumor mass, obtaining RT = 0. Currently, the patient continues her gyneco-oncology follow-up simultaneously clinically, in laboratory, and instrumentally every 4 months. Our study currently represents the longest elapsed time interval between first diagnosis and disease recurrence, as evidenced by current data in the literature. This was a rather unique and difficult clinical case because of the rarity of the disease, the lack of scientific evidence, and the difficulty in differentiating the primary hepatoid phenotype of the ovary from an ovarian metastasis of HCC. Several multidisciplinary meetings for proper interpretation of clinical and anamnestic data, with the aid of immunohistochemistry (IHC) on histological slides were essential for case management.

Rare Case of BCOR::CCNB3 Sarcoma of Bone

BACKGROUND BCOR

CCNB3 sarcoma is a rare mesenchymal tumor that was formerly included in the undifferentiated/unclassified sarcoma group and was recently reclassified as one of undifferentiated small round cell sarcomas with a genetically distinct subtype in the WHO 2020 classification. Because of its rarity, still not much is known, especially about its clinical features. CASE REPORT A 15-year-old boy presented with almost 1-year intermittent thigh pain. On the first visit, a pathologic fracture of the femur and a big mass expanding through the femoral cortex with lobular shape and homogenous appearance were recognized on radiography and magnetic resonance imaging. Plain radiography, which was taken 6 months before at a local clinic, showed an expansion and thickening of the right proximal femoral shaft. Biopsy specimen of the lesion revealed a proliferation of round to spindle tumor cells with diffuse and strong immunohistochemical nuclear positivity for BCOR and CCNB3. Under the diagnosis of BCOR::CCNB3 sarcoma of the femur, a chemotherapy based on a protocol of Ewing sarcoma, followed by a wide resection and total femoral replacement surgery, were conducted. The effect of chemotherapy was favorable, showing no microscopic residual tumor. Although postoperative chemotherapy was not completed because of a minor infection detected on the surgical site, the patient was doing well, without any recurrence, for 26 months.

CONCLUSIONS BCOR

CCNB3 sarcoma of the bone is a quite rare tumor with much lower incidence than Ewing sarcoma. Notable clinical characteristics of the current case were a 1-year-long symptomatic period and homogenous appearance on MRI.

Spontaneous Iliac Vein Ruptures: A Systematic Review

INTRODUCTION

Spontaneous iliac vein rupture is a rare, but frequently lethal condition. It is important to timely recognize its clinical features and immediately start adequate treatment. We aimed to increase awareness to clinical features, specific diagnostics, and treatment strategies of spontaneous iliac vein rupture by evaluating the current literature.

METHODS

A systematic search was conducted in EMBASE, Ovid MEDLINE, Cochrane, Web of Science, and Google Scholar from inception until January 23, 2023, without any restrictions. Two reviewers independently screened for eligibility and selected studies describing a spontaneous iliac vein rupture. Patient characteristics, clinical features, diagnostics, treatment strategies, and survival outcomes were collected from included studies.

RESULTS

We included 76 cases (64 studies) from the literature, mostly presenting with left-sided spontaneous iliac vein rupture (96.1%). Patients were predominantly female (84.2%), had a mean age of 61 years, and frequently presented with a concomitant deep vein thrombosis (DVT) (84.2%). After various follow-up times, 77.6% of the patients survived, either after conservative, endovascular, or open treatment. Endovenous or hybrid procedures were frequently performed if the diagnose was made before treatment, and almost all survived. Open treatment was common if the venous rupture was missed, for some cases leading to death.

CONCLUSION

Spontaneous iliac vein rupture is rare and easily missed. The diagnose should at least be considered for middle-aged and elderly females presenting with hemorrhagic shock and concomitant left-sided DVT. There are various treatment strategies for spontaneous iliac vein rupture. An early diagnose brings options for endovenous treatment, which seems to have good survival outcomes based on previously described cases.

Laparoscopic Ureterolithotomy and Single-Use Digital Flexible Ureteroscope For Unilateral Large Ureteral Stone and Small Renal Stone

BACKGROUND The removal of concurrent ureteral and renal stones within a single procedure has always been a challenge for urological surgeons. The incorporation of single-use digital flexible ureteroscopes into laparoscopic ureterolithotomy procedures has demonstrated effective removal of concurrent stones with a good clearance rate and decreased risk of bleeding and trauma. We report the successful removal of a unilateral upper ureteral stone and a smaller renal stone with this procedure. CASE REPORT A 60-year-old man visited the outpatient clinic with an ultrasonography report that revealed a large proximal ureteral stone with moderate hydronephrosis, accompanied by bilateral renal stones and prostatic hyperplasia. He had been experiencing urinary urgency for a year and was determined to undergo lithotomy. Due to his longstanding history of coronary artery disease and myocardial ischemia, the urologists decided that concurrent stone removal within an operation would be the best treatment. A preoperative computed tomography urogram measured the left ureteral and renal stones to be 2.0×0.8 cm and 0.6 cm, respectively. Both stones were successfully removed by laparoscopic ureterolithotomy using a single-use digital flexible ureteroscope. The patient had an uneventful recovery and remained well 1 month post-operation. CONCLUSIONS The application of single-use digital flexible ureteroscopes for laparoscopic ureterolithotomy has demonstrated safety, efficiency, and cost-effectiveness. The authors believe that it is a safe alternative for the removal of concurrent ureteral and renal stones, especially in patients with multiple comorbidities.

Extraction of a Bi-Rooted Primary Maxillary Canine Tooth in a 9-Year-Old Saudi Boy: A Case Report

BACKGROUND Dental anomalies are common congenital disturbances that can occur as single findings or as components of specific syndromes. Primary bi-rooted canine teeth are rare dental anomalies that are more common in the maxilla. It is unusual for a child to have a bi-rooted maxillary canine, as this tooth is known for having a single long root, more than twice the length of the crown. The present report describes the extraction of a bi-rooted primary maxillary canine tooth in a 9-year-old Saudi boy. The report aims to contribute to a better understanding of the possible etiological factors of these rare conditions as well as to review the data available so far in the literature. CASE REPORT A 9-year-old Saudi boy presented to the clinic for an initial visit. The patient was medically fit. The chief complaint was "I have pain in my upper front left region". A thorough oral examination revealed that the upper left primary canine was carious. The panoramic radiograph showed that the former tooth was bi-rooted. The tooth was claimed to be non-restorable. Thus, we planned for extraction. The tooth was extracted in the subsequent visit. CONCLUSIONS The presence of bi-rooted primary canines is rare. Dentists should always assess the presence of any dental abnormality. Panoramic radiographs may give an initial sign of the existence of abnormal bi-rooted teeth, and the abnormality can be confirmed by taking intraoral radiographs. Although the data availability in the literature is limited, ethnicity and gender seem to have an impact on its prevalence.

Age is just a number: the concept of time to benefit in older adults

A female nursing home resident aged >70 years was admitted to the geriatric ward with de novo dysphagia 6 days after being discharged from the stroke unit. Metformin and ezetimibe had been added to her treatment regimen which already consisted of clopidogrel, atorvastatin, denosumab, calcium and vitamin D. At the geriatric ward a multidisciplinary team involving clinical pharmacists reviewed all treatments and appraised the time to benefit, ascertaining whether there was sufficient time left to experience therapeutic benefits. As a result, metformin, ezetimibe, denosumab, calcium and vitamin D were discontinued. This case report illustrates that both mortality risk assessment and evaluation of the time to benefit should be part of any medication review in frail older adults. Conversely, with limited available data pertaining to the concept of time to benefit, we advocate a broader awareness among pharmacists and a systematic assessment in future clinical trials.

Haemolytic anaemia induced by flutamide: a case report

Flutamide-induced haemolytic anaemia is rare but can be fatal. We describe the case of an 88-year-old man with prostatic carcinoma who, in addition to clinically obvious jaundice, developed haemolytic anaemia after undergoing treatment with flutamide for 5 days. When flutamide was replaced with temporary adrenocortical hormone treatment and blood transfusion, the blood indices and liver function of the patient improved gradually. We emphasise the need for routine monitoring of blood counts for patients undergoing flutamide treatment, and highlight the importance of discontinuing flutamide immediately when haemolytic anaemia occurs.

Improved Balance, Gait, and Lower Limb Motor Function in a 58-Year-Old Man with Right Hemiplegic Traumatic Brain Injury Following Virtual Reality-Based Real-Time Feedback Physical Therapy

BACKGROUND This report presents the case of a 58-year-old man with right hemiplegia who improved his gait and lower limb motor function following virtual reality (VR)-based physical therapy. The use of augmented reality or VR-based technology is being increasingly used to support physical therapy in patients with motor deficits and to improve gait, and can be used in small hospitals and outpatient departments. CASE REPORT A 58-year-old man was diagnosed with left hemiplegia due to traumatic brain injury (TBI). He received 20 minutes of VR-based real-time feedback gait training and 30 minutes of general physical therapy, 5 times a week for 8 weeks. BioRescue was used for measurement of balance, GAITRite was used for measurement of gait, and Fugl-Meyer assessment was used for lower extremity motor function measurement. These were measured before the intervention and at 2, 4, 6, and 8 weeks after the intervention. After the intervention, center of pressure and limits of stability also increased. The affected step length, stride length, affected single support, and cadence were significantly increased after VR-based real-time feedback. Additionally, his lower extremity motor function score increased from 18 to 23 points. CONCLUSIONS This case report supports recent studies that have shown the value of VR-based methods as part of a physical therapy program in patients with problems with gait and motor function, including patients with stroke. VR-based real-time feedback showed favorable effects on rehabilitation following a TBI.

Reconstruction of complex knee wounds with a distally based gracilis flap and gastrocnemius myocutaneous flap: A case report

A gastrocnemius muscle flap is a versatile option for covering the proximal one-third of the lower leg and around the knee. On the other hand, it is of limited use in patients with short gastrocnemius muscle or insufficient volume. The authors present a case in which a knee soft tissue defect occurred in a very thin patient and was reconstructed using a gastrocnemius myocutaneous flap and a distally based gracilis flap as a supplementary flap.

Mitral Valve Replacement for Enlarged Libman-Sacks Endocarditis in a Patient with Persistent Primary Antiphospholipid Syndrome and Recurrent Stroke: A Case Report

BACKGROUND Anticardiolipin antibodies in patients with Libman-Sacks endocarditis (LS) are indicative of comorbid antiphospholipid syndrome (APS) and can result in cerebral infarctions. We describe a case of LS and primary APS with recurrent cerebral infarctions despite anticoagulation treatment. The patient underwent surgery for enlarged LS vegetation with high titers of antiphospholipid antibodies. CASE REPORT A 41-year-old Japanese man was admitted to hospital for small cerebral infarction recurrence in a left parietal lesion. At age 35, the patient had suffered multiple cerebral infarctions. He was found to have high serum titers of all 3 antiphospholipid antibodies. Transesophageal echocardiography (TEE) findings were normal. Differential diagnosis ruled out other autoimmune diseases and a clinical diagnosis of primary APS was made. Warfarin anticoagulation was started. When cerebral infarction recurred 6 years after the first episode, serum titers of antiphospholipid antibodies remained high, and TEE showed a 7×8 mm area of mitral vegetation. A TEE results from his first admission revealed a 5×6 mm area of mitral vegetation, which was believed to be related to the current vegetation. As anticoagulation produced no improvement, the mitral valve was replaced with a mechanical valve. Examination of the excised vegetation found it to be consistent with LS. The patient made good progress within 3 years after surgery. CONCLUSIONS LS size can increase despite anticoagulation in cases with high titers of all 3 antiphospholipid antibodies and cerebral infarction. Such patients require ongoing TEE follow-up and surgical treatment should be considered.
