When resecting the internal jugular veins bilaterally in surgery for head and neck cancer, it is necessary to perform neck dissection in two stages or to reconstruct the internal jugular veins in one stage. Reconstruction of the internal jugular vein using grafting or direct anastomosis to the external jugular vein have both been reported. We report the case of a 53-year-old man with accidental injury to the left internal jugular vein after resection of the right internal jugular vein for supraglottic cancer. The left internal jugular vein was damaged near the inflow of the subclavian vein, making vein grafting difficult. Therefore, internal jugular venous return was reestablished by end-to-side anastomosis of the left internal jugular vein to the left external jugular vein system. In this surgical procedure, by incising the internal jugular vein obliquely, it was not necessary to match the calibers of the internal jugular vein and the external jugular vein system, and a smooth hemodynamic body was reconstructed. In addition, we were able to reconstruct the internal jugular vein while preserving blood flow in the external jugular vein system. End-to-side anastomosis of the internal jugular vein to the external jugular system is an option for internal jugular vein reconstruction.

Congenital nephrogenic diabetes insipidus (CNDI) is a rare disease that results in polyuria due to decreased responsiveness to the antidiuretic hormone in the collecting ducts of the kidney. Without compensation by drinking large amounts of water, dehydration and hypernatremia can rapidly develop. We present a case of a patient originally diagnosed with CNDI who required surgery and a fasting period due to adhesive bowel obstruction. The patient was a 46-year-old man who was originally diagnosed with CNDI. He was prescribed trichlormethiazide but self-discontinued treatment in the process. His normal urine output was about 7,000–8,000 mL/day. He underwent robot-assisted radical cystectomy and uretero-cutaneostomy for bladder cancer. Two years later, he was hospitalized due to adhesive bowel obstruction. A 5% glucose solution was infused, and the dose was adjusted according to the urine volume and electrolytes. An adhesiotomy was performed due to recurrent bowel obstruction in a short period of time. A 5% glucose solution was used as the main infusion during the perioperative period. Once drinking water was resumed after surgery, urinary output and electrolytes were easily controlled. In conclusion, patients with CNDI should be given a 5% glucose solution as the primary infusion, and the infusion volume should be adjusted by monitoring daily urine output, electrolytes, and blood glucose levels. Infusion management is easier if oral intake is initiated as early as possible.

Cesarean section can lead to residual myometrial thickness thinning and cesarean scar syndrome. We report a novel trimming technique for residual myometrial thickness recovery in women with cesarean scar syndrome. Case 1: A 33-year-old woman who developed cesarean scar syndrome (CSS) and abnormal uterine bleeding post-cesarean scar became pregnant following hysteroscopic treatment. The myometrium at previous scar was dehiscent; therefore, a transverse incision was made above the scar. Post-operative uterine recovery failed owing to lochia retention, and developed cesarean scar syndrome again. Case 2: A 29-year-old woman who developed cesarean scar syndrome post-cesarean section became pregnant spontaneously. The myometrium at the previous scar was dehiscent like case 1. Scar repair was performed using a trimming technique during cesarean section; there were no subsequent complications and she conceived again spontaneously. Performing this novel surgical procedure during cesarean section may contribute to residual myometrial thickness recovery in women with cesarean scar syndrome.

Garré’s osteomyelitis, first described by Carl Garré in 1893, is a type of chronic osteomyelitis accompanied by hyperplastic periostitis. This condition affects relatively young patients and occurs in the fibula, femur, and other long bones as chronic non-purulent sclerosing osteomyelitis. Further, reactive periosteal bone formation develops due to chronic irritation or infection. In the maxillofacial region, it often occurs in the first molar region of the mandible due to caries and other similar causes, and it is rarely associated with impacted teeth. Herein, we present a 12-year-old female patient who primarily complained of swelling on the right side of the mandible. Despite taking antibiotics prescribed at local otolaryngologist, the swelling did not completely resolve. Thus, the patient was referred to the Department of Otorhinolaryngology at our hospital, where a dental-related disease was suspected. On a computed tomography scan, radiolucent findings were observed around the germ of the impacted wisdom tooth as well as hyperostosis in the lower jaw. Thus, Garré’s osteomyelitis was suspected. The patient received oral anti-inflammatory treatment by the incision prior to surgery. Thereafter, the tooth germ was enucleated and newly-formed bone, which was laterally located to the cortical bone of the mandible, was removed under the effect of general anesthesia. On computed tomography scan 9 months after the surgery, hyperostosis in the angle of the mandible disappeared. Thereafter, pain and swelling did not recur, and the patient was doing well.

Posterior reversible encephalopathy syndrome (PRES) is characterized by transient vasogenic edema predominantly in supratentorial areas within the posterior circulation regions. Although PRES with only brainstem involvement is quite rare, accurate diagnosis is important because prompt antihypertensive therapy contributes to a favorable outcome. Herein, we report a case with isolated brainstem PRES showing dramatical improvement in an apparent diffusion coefficient (ADC) value of the lesion in magnetic resonance imaging (MRI) after clinical remission. The present case suggests the association between favorable clinical course and complete amelioration on MRI.

Positive thinking is one of the psychological skills that mental training programs aim to help athletes cultivate in order to enhance performance. It has been noted, however, that some athletes do not find positive thinking effective for that purpose. This case report describes a fencing athlete who used positive thinking to cope with negative ruminations prior to a competition and then stopped using positive thinking and engaged in mindfulness. As a result of applying mindfulness, the patient developed the ability to take part in competitions without obsessing and without negative ruminations. These findings show the importance of assessing, in detail, how the psychological skills training used with athletes is affecting their cognition, behavior, and performance and of implementing appropriate interventions based on these assessments.

Chronic active Epstein–Barr virus (CAEBV) infection is a rare disease, mainly affecting children, typically characterized by persistent infectious mononucleosis (IM)-like symptoms. We describe an adult case of CAEBV without IM-like symptoms, which was indistinguishable from autoimmune hepatitis (AIH). A 60-year-old woman with liver damage was diagnosed with AIH (International Diagnostic Score: 16 points). She had been treated with prednisolone for three years; however, her transaminases had never normalized. She was admitted for another liver biopsy due to repeated high fevers and worsening of her liver damage over two months. Her EBV-DNA copy number was 2.9 × 10(4) copies/μg DNA, and EBV-encoded small RNA1-positive lymphocytic infiltration was observed in both the present and previously collected (three years ago) liver tissue samples. This case implies that hepatic involvement in a CAEBV without IM-like symptoms is difficult to distinguish from AIH and may be misdiagnosed. In some steroid resistant AIH cases, evaluating for CAEBV may be valuable.

We report herein a case of gallbladder cancer with biliary intraepithelial neoplasia (BilIN) complicated by pancreaticobiliary maljunction (PBM). A 60-year-old woman was referred to our hospital for thickening of the gallbladder wall diagnosed via ultrasonography at the referring clinic. The Radiographic images showed thickening of the gallbladder wall and a high confluence of pancreaticobiliary ducts outside the duodenal wall without dilatation of the bile duct. The amylase level in the bile duct was highly elevated. The patient was initially diagnosed with PBM without biliary dilatation, and laparoscopic cholecystectomy was performed. Histopathology of the resected specimen revealed gallbladder cancer localized in the mucosa propria with widespread BilIN. Immunohistochemical analyses showed positive results for S100P,IMP3 and p16(ink4a) in tumor cells, but a positive result for only IMP3 in adenocarcinoma. Expression of p53 was negative. Oncogenic KRAS mutations were not detected in tumor cells. The patient was diagnosed with gallbladder cancer with BilIN complicated by PBM. This case report may be useful in clarifying the carcinogenic process and genetic mutations for gallbladder cancer associated with PBM.

Pyloric gland metaplasia in the biliary epithelium is a precancerous lesion and has been confirmed in patients with congenital biliary dilatation presenting with overt biliary tract cancer. A patient was found to have an intra-abdominal cyst on fetal ultrasonography and was born at 37 weeks of gestation with a body weight of 2,636 g. Abdominal distension and repeated vomiting appeared 2 days after birth. Congenital biliary dilatation was diagnosed by imaging, wherein the common bile duct was enlarged to 9–10 cm in size, and the surrounding organs were extensively compressed; however, there was no sign of pancreatitis or cholangitis. Biliary drainage was performed through the gallbladder at 6 days of age, but it was insufficient because of the narrow and twisted cystic duct and changed to common bile duct at 18 days to relieve the compression. Because the body weight gain was poor due to loss of large amount of bile, the dilated bile duct and gallbladder were resected and hepatic duct Roux-Y jejunostomy was performed at 115 days of age with 4,500 g of body weight. Intraoperative imaging showed a pancreaticobiliary maljunction, and the pancreatic enzyme activities of the bile in the biliary system were remarkably elevated. Histopathological examination revealed pyloric gland metaplasia in the gallbladder epithelium and cystic duct. The patient is now over 2 years old and has been doing well without any complications. Based on our experience, precancerous pyloric gland metaplasia of the biliary epithelium may already occur even in a 3-month-old infant presenting with congenital biliary dilatation.

In defecation training, parent-mediated intervention via teleconsultation is helpful because the number of instructions for establishing defecation habits is limited. In the case report of the present study, defecation training was conducted based on gradual target setting and differential reinforcement through teleconsultation via email for a Caucasian 5-year-old boy with autism spectrum disorder (ASD) who lived in Greece. As a result of the intervention, namely the gradual target setting and differential reinforcement, in-bowl defecations increased at home.

This report describes a rare case of brachial artery dissection associated with closed elbow dislocation caused by a snowboarding injury. After peripheral ischaemic findings in the right upper extremity were confirmed, urgent duplex-sonography was performed to diagnose the brachial artery injury. Urgent revascularisation surgery was promptly performed, and arterial dissection was diagnosed by intraoperative findings, in which the adventitia of the brachial artery was intact and the intima was disrupted. In this case, because there was no golden time window before undertaking urgent revascularisation surgery, duplex-sonography was very useful for making an emergency diagnosis. To diagnose arterial dissection, because the adventitia of the brachial artery is intact, it is necessary to perform arteriotomy to identify intimal disruption in the brachial artery. When diagnosing traumatic elbow dislocation, it is important to suspect arterial dissection.

Upper tract urothelial carcinoma (UTUC) is a relatively rare disease that accounts for 5% to 10% of all urothelial carcinomas (UCs). Radical nephroureterectomy (RNU) with a bladder cuff is the current gold standard for the management of UTUC; however, endoscopic ablation is also an option for low-risk UTUC to preserve kidney function. Herein, we present two cases of solitary kidney with a right lower ureteral tumor. Both patients underwent left RNU in the past. An 82-year-old man with a right ureteral tumor whose histopathological examination revealed low-grade UC. Laser ablation was performed with ureteroscopy, and there was no recurrence for 7 years after treatment. A 67-year-old woman with a right lower ureteral tumor whose histopathological examination also revealed low-grade UC. Laser ablation was performed, and there was no recurrence for 5 years after the treatment. We closely followed-up our two patients after RNU. This allowed for early detection of tumor recurrence, after which we could perform laser ablation therapy.

Intractable pneumothorax with poor lung function that has received multiple conservative treatments may occur. Case 1 was a 70-year-old woman with aspergilloma who was admitted for pneumothorax. Case 2 was a 68-year-old man with acute exacerbation of interstitial pneumonia who developed pneumothorax. In both cases, multiple conservative therapies were administered, but the leak continued; thus, operations using veno-venous extracorporeal membrane oxygenation (ECMO) were planned. By video-assisted thoracoscopic surgery (VATS), we obtained the optimal surgical field by lung collapse. We removed many blood clots that were used for pleurodesis, ligated the bulla in case 1, and covered the leak point with strengthening agents in case 2. For cases of intractable pneumothorax, lung collapse by ECMO is advantageous because we can check details and leak points even in blood clots or in poor condition of the lung, and we can maneuver the lung in poor condition with a clear surgical field.

We report a case of robot-assisted total hysterectomy in a patient with extremely rare pelvic anatomy. Robot-assisted total laparoscopic hysterectomy was performed for lobular endocervical glandular hyperplasia on the left side of the uterus. The sigmoid colon was present between the two uterine corpora of a uterine didelphys and was attached to the bladder via the mesentery and fat. During surgery, the surgeon left the console and confirmed the magnetic resonance images. The surgery was then completed safely after the surgeon understood the anatomy. The postoperative condition was good, and the patient was discharged on postoperative day 5. Robot-assisted surgery has various advantages, including a good field of view, accuracy of instrument movement, and ease of viewing information in the medical record by pausing the operation. Robot assisted surgery improves not only safety and operational precision but also intraoperative convenience. Further studies are needed regarding the specific anatomy seen in this case.

Surgical removal of tumor is the primary treatment of choice for glomus tympanicum (GT). However, because the tumor has abundant blood flow, bleeding control is crucial, and preoperative embolization may be performed. Here, we report the case of a 46-year-old female who visited our hospital with a complaint of right pulsatile tinnitus. A red pulsatile mass was found in the right tympanic cavity, and she was diagnosed with class B1 GT and subsequently underwent surgical treatment. We judged that bleeding could be controlled by intratympanic cavity manipulation alone and decided to perform transmeatal tumor resection without preoperative arterial embolization. After creating a tympanomeatal flap and performing an atticotomy, some pieces of Spongel(®) were inserted between the tumor and the tympanic wall. The Spongel(®) absorbed the blood and created a space between the tumor and tympanic wall, which allowed for the insertion of the tip of the Vesalius(®) handpiece to coagulate the tumor. The coagulation caused the tumor to shrink, thereby widening the space and allowing for further resection. Although the surgical manipulation caused bleeding, complete resection was achieved by the application of Spongel(®) and coagulation with Vesalius(®). Since the tip of the Vesalius(®) was not burned, hemostasis was successfully achieved, and the operation proceeded while maintaining a clear field of view. There was little bleeding and no postoperative complications. The patient was discharged on the sixth postoperative day. One year after surgery, pure tone audiometry showed no change in the level of bone conduction. Spongel(®) and Vesalius(®) are useful tools that allow to safely perform surgeries even in narrow spaces such as the tympanic cavity.

INTRODUCTION The management of multiple dimensions in orthognathic surgery often requires careful planning. Too large discrepancies could require a sequential procedure to make alignment of the archs possible. REPORT OF CASE The authors report a case of a 30-year-old partially edentulous man with severe maxillary hypoplasia caused by an untreated ankyloglossia. The transverse deficiency was estimated at more than 15 mm and the sagittal discrepancy shows a negative overjet of 11.5 mm. These wide deficits needed a 2-step surgery and the use of computed-aided design/computed-aided manufacturing. The first step was a palatal expansion by a fan-shaped Le Fort I osteotomy. The second step treated sagittal discrepancy and re-expanded the maxilla.At the end, the sagittal dimension got normal and the maxilla have been widened to almost 7 mm. CONCLUSION Custom-made surgery is very useful for uncommon cases, in particular for toothless patients. It facilitates complex operations and allows precise results.

Gorham-Stout disease, a rare and intractable disease of unknown etiology, causes systemic bone lysis and replacement with lymphoid tissue. Here, we report a case of Gorham-Stout disease with cerebrospinal fluid leakage in a 16-year-old boy. The patient complained of nasal discharge, right ear obstruction, fever, and headache. A computed tomography scan of the head showed osteolysis around the right internal carotid artery, vestibule, and cochlea and osteolytic changes in the left parietal bone. It was suggested that the patient had bacterial meningitis owing to the leakage of cerebrospinal fluid from the fistula caused by the temporal bone osteolysis. He was treated with meropenem, and a transmeatal fistula closure and a bone biopsy of the left parietal bone were performed. Intraoperatively, osteolysis was observed on the promontory and around the internal carotid artery. The fistula was closed by dense filling and compression around the fistula, in the middle ear cavity, and in the external auditory canal. The symptoms disappeared after the surgery. Bone biopsy showed the presence of a lymphangioma, and Gorham-Stout disease was diagnosed. Prophylactic bisphosphonate therapy was initiated. A 4-year follow-up revealed no progression of the disease.

Objectives The prehospital identification of stroke patients with large vessel occlusion (LVO) enables appropriate hospital selection and reduces the onset-to-treatment time. The aim of this study was to investigate whether the Field Assessment Stroke Triage for Emergency Destination (FAST-ED) scale could be reconstructed from existing prehospital patient reports and to compare its performance with neurologist's clinical judgement using the same prehospital data. Materials & Methods All patients transported by ambulance using stroke code on a six-month period were registered for the study. The prehospital patient reports were retrospectively evaluated using the FAST-ED scale by two investigators. The performance of FAST-ED score (>= 4 points) in LVO identification was compared to neurologist's clinical judgement ('LVO or not'). The presence of LVO was verified using computed tomography angiography imaging. Results A total of 610 FAST-ED scores were obtained. The FAST-ED had a sensitivity of 57.8%, specificity of 87.2%, positive predictive value (PPV) of 37.3%, negative predictive value (NPV) of 93.4% and area under curve (AUC) of 0.724. Interclass correlation coefficient for both raters over the entire range of FAST-ED was 0.92 (0.88-0.94). The neurologist's clinical judgement raised sensitivity to 79.4%, NPV to 97.1% and PPV to 45.0% with an AUC of 0.837 (p < .05). Conclusions The existing patient report data could be feasibly used to reconstruct FAST-ED scores to identify LVO. The binary FAST-ED score had a moderate sensitivity and good specificity for prehospital LVO identification. However, the FAST-ED was surpassed by neurologist's clinical judgement which further increased the sensitivity of identification.

Fecal impaction is the impaired excretion of a large fecal mass, and mild cases are treated by enema and osmotic laxatives. However, treatment-resistant cases need more invasive alternatives. A woman in her 60s presented with abdominal discomfort. Her abdomen was soft and without tenderness. Computed tomography revealed a large mass of feces in her sigmoid colon and no intestinal dilatation proximal to the mass. Endoscopy confirmed a fecal mass occupying the lumen. A glycerin enema, oral administration of polyethylene glycol, and enteral administration of amidotrizoic acid during colonoscopy were ineffective. We maneuvered a guidewire to form a loop at the tip of an endoscope, with which we subdivided the mass for successful removal. The patient’s abdominal discomfort disappeared immediately. Endoscopic disimpaction is far less invasive than surgery and should be considered when treating fecal impaction cases, without severe obstructive colitis, which are nonresponsive to conservative treatment.

Background Adult colorectal surgery patients continue to have high rates of readmissions, despite known risk factors for non-routine postdischarge care (emergency department (ED) visit or rehospitalization) and countless interventions to address these. It is unclear how the difficult-to-quantify patient perspective frames and modifies the impact of these quantifiable risk factors. Study design We identified consecutive adult inpatient colorectal surgery patients from 2017 to 2018. This mixed methods study merged data from electronic health records and in-depth patient interviews. Results We enrolled 258 participants, surveyed 167, and interviewed 18. Depressive symptoms represent one of many risk factors confirmed to increase non-routine healthcare utilization (RR 1.85, 95% CI 1.02–3.37), though the patient perspective explained why these symptoms seemed to greatly impact some patients more than others. Additionally, consistent with patient report, patients with non-routine postdischarge care (26%) were less likely to report communication with their surgical team (80% vs 97%, p Conclusion Patient perspectives add depth and understanding of the impact of risk factors on non-routine post-discharge care. This expanded knowledge explains why one patient is more likely to visit an ED close to home whereas another patient might prefer to visit their surgeon’s clinic directly. Effective strategies to reduce unplanned postdischarge care should be tailored.

We present a rare case of concurrent resection of pancreatic and gastric cancer in which indocyanine green (ICG) fluorescence was used to evaluate the remnant stomach. An 80-year-old man was referred with a tumor in the distal pancreas. Computed tomography showed a 25-mm mass in the pancreatic tail; endoscopic ultrasound-guided fine-needle aspiration revealed adenocarcinoma. Upper gastrointestinal endoscopy and subsequent upper gastrointestinal series revealed advanced gastric cancer in the mid-stomach. Concurrent resection of the pancreatic and gastric tumors was performed. After distal pancreatectomy and distal gastrectomy, ICG evaluation of the stomach showed fluorescence extending only 3 cm distal from the cardia. To avoid ischemic change at the remnant stomach, total gastrectomy was performed. Since remnant gastric necrosis and anastomotic leak following ischemia can lead to fatal outcomes, the use of ICG to evaluate blood supply at anastomotic sites can help determine the extent of safe resection in such cases.

We report the case of a 65-year-old male who presented with a 1-week history of right periorbital pain and progressive visual loss. He had a history of ulcerative colitis and was taking oral corticosteroids and mesalazine. Neurological and radiological examination demonstrated a rare case of invasive fungal rhinosinusitis that began with orbital apex syndrome. Initial endoscopic sinus surgery was performed and fungal culture identified Aspergillus fumigatus. Although antifungal treatment was started empirically before the operation, the patient had improved orbital pain but continued to have decreased right vision. Five months after the first surgical procedure, his condition deteriorated, including loss of consciousness, and a right temporal lobe abscess was found and surgically drained. Since then, the patient received antifungal treatment for 4 years without recurrence. Invasive fungal rhinosinusitis with orbital apex syndrome should be treated with long-term postoperative antifungal medication. It should be noted that even in immunosuppressive individuals such as ulcerative colitis, fungal rhinosinusitis with orbital apex syndrome may become severe.

Recent studies have shown that complete lymph node dissection (CLND) performed immediately did not improve the overall survival in patients with sentinel lymph node (LN)-positive melanoma. According to these results, nodal observation with ultrasonography becomes standard. However, it still has some limitations for detection of metastatic LNs. A 74-year-old woman was diagnosed with acral lentiginous melanoma of her left sole. The sentinel LN was positive for metastasis, but she refused CLND. Sixteen months after operation, ultrasonography showed an abnormal LN in the inguinal region. There was no other abnormal LNs around the LN. We resected the abnormal LN. The resected LN was black in color, and the adjacent LN that showed normal appearance in ultrasonography was also black. A recent study showed only 6.6% sensitivity in preoperative ultrasonographic detection of metastatic melanoma in a LN. We should keep in mind the limitation of ultrasonography for detection of a metastatic LN.

Cetuximab is an effective drug used to treat patients with recurrent or metastatic head and neck squamous cell carcinoma. Skin toxicities such as paronychia and skin exsiccation are common adverse events caused by cetuximab. Skin toxicities may cause significant physical and psychosocial discomfort. The goal of managing skin toxicities is to minimize the detrimental effects on quality of life and continue the treatment. In one patient, skin toxicities became severe, up to grade 2, during treatment. The pain induced by paronychia and skin exsiccation made daily life difficult. Ten days after starting Unseiin, symptoms and finger findings resolved significantly. The patient could resume daily activities. No adverse effects induced by Unseiin were observed during treatment. Unseiin was effective on paronychia and skin exsiccation in this case and may contribute to successful treatment of skin toxicities induced by cetuximab.

We report a case of GCTB in an 84-year-old Japanese man who had a tumor in his left iliac bone and was treated safely with denosumab. The patient noticed a painful mass, with gradual enlargement, in his left low back next to the iliac region. Magnetic resonance imaging revealed that the tumor measured 94 × 66 × 90 mm and was located in the left iliac bone. Histologically, the tumor was composed of proliferative oval-shaped mononuclear cells, admixed with large number of osteoclast-like giant cells. Immunohistochemically, a strong positivity for histone 3.3 G34W mutant protein was observed in the nuclei of the mononuclear cells, confirming the diagnosis of GCTB. Because it was considered as unresectable tumor, the patient was treated with denosumab without any side effects.

Herein, we report a case of atypical spindle cell lipomatous tumor (ASCLT) on both sides of the tongue in a 74-year-old male patient. The patient was referred to our department for treatment of the masses in the tongue. Several elastic soft indolent masses were detected during the first examination. The masses were well defined, and their consistency was similar to that of adipose tissues. No signs of induration were observed in the surrounding tissues. The patient was not aware of the masses, which were only detected during his visit at the dental clinic that referred him to our institution. Thus, the onset of the masses remains unknown. ASCLT was identified via histopathological examination. Then, tumor excision was performed under general anesthesia. Thirteen months after surgery, the condition of the patient was good, and signs of local recurrence or postoperative metastasis were not observed.

Reconstruction of bone and soft-tissue defects in the forearm is a surgery that often proves unsuccessful. Free fibular osteocutaneous flaps are a useful material for reconstruction that enable simultaneous reconstruction of bone, skin, and soft tissues. However, in free fibular osteocutaneous flaps, the fibula, skin, and vascular pedicle are tightly bound together by the posterior intermuscular septum and the perforators that pass through the septum, giving the disadvantage of a low degree of freedom when setting these structures in place. We take into account the 3-dimensional structure of the free skin flap when selecting which lower leg to use as the donor. We report here the case of a 61-year-old man with defects in the radius, skin, and soft tissues after resection of spindle cell carcinoma of the right forearm, which was reconstructed using a free fibular osteocutaneous flap harvested from the left lower leg. Two years postoperatively, recovery has been uneventful with no complications. Donor-side selection of free fibular osteocutaneous flap is an important factor for safely completing composite radius reconstruction.

We present the case of a 58-year-old Japanese woman with a natural killer T (NK/T)-cell lymphoma complicated by brain abscess. NK/T-cell lymphomas represent a rare type of lymphoma derived from either activated NK cells or, rarely, cytotoxic T cells. They are aggressive Epstein-Barr virus (EBV)-associated lymphomas that involve mainly the nasal cavity. Brain abscess associated with primary extranodal nasal-type NK/T-cell lymphoma is extremely uncommon: to our knowledge, this is the first reported case of this lymphoma with brain abscess as the initial clinical manifestation. Endoscopic surgery was performed for definitive diagnosis under intraoperative navigation system. Chemotherapy followed by radiotherapy was performed and was effective: 72 months later the tumor has not recurred. Recommendations of endoscopic management for diagnosis and treatment of this rare neoplasm are discussed.

We present a very rare case of a laparoscopically-assisted repair of a small bowel perforation secondary to multiple metastases of undifferentiated pleomorphic sarcoma from the posterior mediastinum. A 46-year-old man presented with middle to upper abdominal pain during chemotherapy for lung metastases from undifferentiated pleomorphic sarcoma. Computed tomography revealed intra-abdominal free air, and emergency laparoscopy was performed. Consequently, a perforation was detected in the jejunum, and partial jejunal resection was performed by mini-laparotomy. Pathological examination demonstrated an ulcerated tumor with perforation and four additional tumors in the resected jejunum. Pathological examination also revealed undifferentiated pleomorphic sarcoma in all five tumors. To our knowledge, our case is the first report of a laparoscopically-assisted repair of a small bowel perforation secondary to metastasis of undifferentiated pleomorphic sarcoma. Although the perforation site was unclear preoperatively, laparoscopic observation readily identified the lesion in this patient. Therefore, minimally invasive surgery could be performed successfully with mini-laparotomy following laparoscopic observation. Laparoscopic techniques for the small intestine are viable options, even in acute and uncommon situations, and small bowel perforation secondary to metastasis should be considered in patients with undifferentiated pleomorphic sarcoma and acute abdomen.

A 79-year-old Japanese woman presented with a rare case of metastatic renal cell carcinoma to the left sphenoid sinus with left nasal bleeding. She had previously had right radical nephrectomy for renal cell carcinoma at the age of 64 years and brain and spinal cord infarction at 74 years. Endoscopic examination revealed no mass in the nasal cavity. CT and MRI revealed a tumor in the left sphenoid sinus. The size of the tumor increased gradually from 12 to 15 years after the radical nephrectomy. Complete resection with endoscopic surgery was performed without preoperative embolization. The tumor cells had clear cytoplasm and were arranged in a trabecular pattern lined by a layer of endothelial cells. These findings were identical to the pathological findings of the surgical specimen of the renal cell carcinoma from 15 years previous. A pathological diagnosis of metastatic renal cell carcinoma of clear cell type (grade 1) was made. PET-CT demonstrated no metastasis. The patient’s condition was successfully managed with excision of the tumor, and she remains well with no evidence of recurrence and metastasis 36 months after treatment. Metastatic renal cell carcinoma to the sphenoid sinus is rare, but it might be considered in the differential diagnosis of masses in the paranasal sinus even long after initial treatment of renal cancer.

Uterine adenomyosis is an estrogen-dependent tumor and one of the most common benign diseases in sexually mature women. The frequency of endometrial cancer associated with adenomyosis has been reported to be 18%–66%. On the other hand, endometrial cancer arising in adenomyosis (EC-AIA) is extremely rare. EC-AIA is now considered a different entity from and has a worse prognosis than endometrial cancer with adenomyosis (EC-A). In the present study, we report a case of endometrial cancer with adenomyosis in which endometrial biopsy failed to provide a definitive diagnosis. A 63-year-old female patient presented with endometrial thickening. Endometrial cytology was positive, and magnetic resonance imaging (MRI) showed small lesions suggestive of endometrial cancer with shallow invasion and adenomyosis. However, an endometrial biopsy showed only metaplasia, and careful follow-up was initiated. Subsequent endometrial cytology showed enlarged and round nuclei, uniform chromatin distribution, no thickening of nuclear margins, and abundant cytoplasm appearing in a sheet-like arrangement, suggesting atypical cells of endometrial glands with metaplasia. Three suspicious positive results and one positive result were observed, but repeated biopsies did not lead to the diagnosis of malignancy. The patient underwent diagnostic hysterectomy 19 months after the initial visit. The postoperative histopathological diagnosis was stage IA endometrial cancer (endometrioid carcinoma G1). This case of endometrial cancer associated with adenomyosis was difficult to diagnose. Our findings demonstrate that EC-AIA should be considered even if no lesions were detected by endometrial biopsy.

Lichen nitidus and morphea are common diseases, but an associated localization of both lesions is rare. Here, we describe the first case of lesions distributed along Blaschko's lines. A 24-year-old Japanese woman was referred to our clinic for evaluation of band-like plaques of 18-months history on the right lateral side of her abdomen. In addition, multiple milky-white papules were seen within the plaques. Histopathological examination showed there was sclerosis in the lower half of the dermis and well-circumscribed, dense, papillary dermal lymphohistiocytic aggregations showing a so-called "claw clutching a ball." Immunohistochemical analysis revealed that the morphea and lichen nitidus had similar characteristics. We speculated that unique immunologic events led to the development of lichen nitidus and morphea in our patient.

We report a case of subcutaneous panniculitis-like T-cell lymphoma with diffuse indurated lesions without erythema. A 27-year-old man was referred to us with a 1-month history of fever, general fatigue and indurated skin lesions. The initial examination revealed indurated skin lesions without erythema and subcutaneous tumors in the right lower abdomen, back and buttocks. Histopathology showed a panniculitis predominantly in lobular pattern, and infiltration of atypical lymphocytes in the subcutaneous tissue. Characteristically, there was rimming of individual fat cells by surrounding atypical lymphocytes. Results of laboratory examinations showed hemophagocytic syndrome (HPS). Based on these findings, we made a diagnosis of subcutaneous panniculitis-like T-cell lymphoma without erythema and subcutaneous tumors with HPS. To our knowledge, there has been no report of SPTCL with diffuse indurated lesions without erythema, tumors, or plaque, all of which are considered to be typical characteristics of SPTCL. Positron emission tomography / computed tomography (PET/CT) showed noticeable thickening of diffuse subcutaneous involvement throughout the body. Hence, PET/CT is a useful for the detection of SPTCL as well as its distribution.

OBJECTIVE: Hormone therapy (HT) is an effective treatment for menopause symptoms in select women. This study aimed to determine whether there is different prevalence of HT use based on patient report by women who see different provider specialties. METHODS: This study was a cross-sectional analysis of published data from the Survey of Midlife in the United States (MIDUS), a telephone or self-administered questionnaire of 3294 participants aged 39–90 years. Postmenopausal women were included. Self-reported HT use and provider specialty seen were each assessed by one question. Univariate logistic regression assessed factors possibly related to HT use. Variables with p < 0.1 were entered into a multivariable logistic regression model. RESULTS: Of the 938 postmenopausal respondents, 720 (76%) saw a gynecologist for care. One-hundred and thirty-one (13%) women used HT for menopausal symptoms. Of women using HT, 72 (55%) saw a gynecologist. When controlling for other factors, women who saw a gynecologist had three times higher odds of using HT. The most frequently seen provider specialty was not associated with use. CONCLUSIONS: Women who ever see a gynecologist are more likely to use HT for menopausal symptoms, but fewer women see gynecologists as they age. Generalists are the most seen provider specialty, positioning them to counsel patients about HT.

A 75-year-old female patient presented with a suspected recurrence of a clival chordoma. The tumor was resected using the infratemporal fossa type B and anterior petrosal approach with the help of a neurosurgeon. During cauterization of the trigeminal nerve, the patient developed cardiac arrest for approximately 10 seconds because of the trigemino-cardiac reflex (TCR). After several sternal compressions, there was return of spontaneous circulation. The operation was resumed after the circulatory dynamics stabilized. Subsequently, the surgery was completed with partial resection of the tumor without the recurrence of cardiac arrest. The pathological diagnosis was chondrosarcoma, and postoperative treatment with radiotherapy was started. Stimulation of the sensory branches of the trigeminal nerve induces TCR. There are reports of TCR developing in approximately 10% of skull base surgery cases in the absence of atropine administration. We report a rare case of TCR during the surgical procedure for the treatment of a skull base chondrosarcoma.

We report a case of X-linked recessive ichthyosis with basal cell carcinoma. An 86-year-old man was referred to our department for evaluation of a 1-year history of an ulcer on his left leg. He had suffered from dry skin with scales on his entire body since childhood. Histopathological examination of the lower leg revealed intradermal proliferation of a solid nest of basaloid cells showing unclear palisading in the periphery. Marked hyperkeratosis and hypergranulosis were also seen in the adjacent dermis. Loss of the steroid sulfatase gene was found on chromosome X. Based on these finding, we made a diagnosis of X-linked recessive ichthyosis with basal cell carcinoma. To our knowledge, there has been no report of X-linked recessive ichthyosis with cutaneous malignancy. We discuss the risk of skin cancer in relation to ichthyosis.

A 50-year-old Japanese woman referred to us with erythematous nodules on her left cheek. She had been treated with topical corticosteroids on her left cheek at a previous local clinic for 4 years. A skin biopsy specimen from a nodule showed perifolliculitis and folliculitis with a destruction of hair follicle without epidermal involvement. Based on the patient’s history of the long-term topical corticosteroids and physical examination, we finally diagnosed this case as unilateral steroid-induced rosacea-like dermatitis (SIRD). She stopped topical steroid and was treated with topical application of benzoyl peroxide. One and a half year after starting the treatment, the nodules were flattened. Use of long-term and only unilateral application of topical corticosteroids probably resulted in unique clinical findings in our case. Given the broad clinical differential diagnosis, our case highlights the importance of appropriate application of topical steroids as well as histopathological analysis on any facial erythematous nodules.

Merkel cell carcinoma (MCC) is a rare but aggressive neuroendocrine skin cancer. To diagnose nodal MCC with an unknown primary disease is challenging, and it has to be separated from other nodal metastatic neoplasms. We report a unique case of nodal MCC in head and neck lesions with an unknown primary. A 70-year-old woman was admitted to our department with a right submandibular mass. Fine needle aspiration biopsy was performed and indicated malignancy. F-18-fluorodeoxyglucose positron emission tomography (PET) demonstrated abnormal accumulation in the right submandibular lymph node, right palatine tonsil, and right thyroid gland. For diagnostics and treatment, bilateral selective neck lymph node dissection, right tonsillectomy, and right thyroidectomy were performed. Histopathological examination revealed that most parts of the submandibular lymph node were occupied by diffuse sheets of tumor cells. Contrary to our expectation, malignant cells were not detected in the right palatine tonsil and right thyroid. Immunohistochemistry demonstrated a marked positive reaction for AE1/AE3, chromogranin A, synaptophysin, cytokeratin 20 (CK20) and CD56 and a negative reaction for vimentin, leucocyte common antigen (LCA), thyroid transcription factor-1 (TTF1) and cytokeratin 7 (CK7) in the tumor cells. Immunostaining of Merkel cell polyomavirus-large T antigen (MCPyV-LT) showed a positive reaction and MCPyV-positive MCCs were assessed by PCR analysis, demonstrating that viral copy number was 12.8 copies per cell. These histological findings confirmed the diagnosis of Merkel cell carcinoma of the lymph node. In cases of tumors in the lymph node with a neuroendocrine appearance in head and neck lesions, it is necessary to eliminate the possibility of metastasis from MCC.

Juvenile granulosa cell tumor (JGCT), classified as a sex cord-stromal tumor, is a rare neoplasm. This is an instructive case report of JGCT accompanied by augmented interleukin (IL)-6 secretion. A 13-year-old girl with prolonged fever and delayed puberty was diagnosed with JGCT of the left ovary based on an imaging study and pathological investigation. Although it was not clear whether IL-6 was secreted from the tumor cells, her serum level of IL-6 was very high. After tumorectomy, the patient's symptoms immediately disappeared, her IL-6 level decreased, and she entered puberty. Therefore, augmented IL-6 secretion production induced by tumors should be considered a potential cause of prolonged fever and/or delayed puberty.

Meningiomas constitute approximately 25% of primary spinal cord tumors, and 1% to 5% are calcified. Ossification is a rare event and the etiology of ossification in meningiomas is not well known. We present the case of a 29-year-old female with a rare case of ossified thoracic spinal metaplastic meningioma. The tumor was successfully resected, and pathology confirmed ossified metaplastic meningioma. On histopathological examination, only mature bone tissue and tumor cells were present in the region containing no psammoma bodies, suggesting that the tumor cells had transitioned to mature osteocytes.

Mycosis fungoides, the most common subtype of cutaneous T-cell lymphoma, displays a broad spectrum of clinical, histological and phenotypic variants with different prognostic impacts. The classic immunophenotype is CD3+/CD4+/CD45RO+memory T cells. CD4/CD8 double-negative mycosis fungoides is rare. Here we describe the clinicopathological features of CD4/CD8 double-negative mycosis fungoides in a 55-year-old female with a review of the literature. Although the CD4/CD8 double-negative phenotype appears to be associated with an unusual clinical presentation, it does not appear to confer prognostic significance.

A 71-year-old Japanese male patient presented with a rare case of Glomangiopericytoma (GPC) of the left nasal with obstruction. Complete resection with endoscopic surgery was performed. Immunohistochemical staining for smooth muscle actin, β catenin, cyclin D1, vimentin, and factor 13 were helpful in establishing a definitive diagnosis. Extranasal treatment has been traditionally performed for successful management. However, recent advances in endoscopic treatment have enabled complete endoscopic resection of GPC, minimizing morbidity and facilitating subsequent surveillance for recurrence. Endoscopic management should be considered in suitable cases.

Descending necrotizing mediastinitis (DNM) is a life-threatening disease with a high fatality rate that occurs as a complication of deep neck abscess. DNM complicated by severe dysphagia during the postoperative period has been previously reported, but there have been no published cases of surgical treatment for severe dysphagia secondary to DNM. A 63-year-old man was diagnosed with a deep neck abscess followed by DNM. The patient had dysphagia after incision and drainage of the abscess and drainage for DNM with video-assisted thoracic surgery (VATS). A comprehensive long-term physiotherapy program with a speech and language therapist did not reduce his dysphagia. Thus, the patient underwent laryngeal elevation and cricopharyngeal myotomy, which enabled oral intake. Surgery should be considered for prolonged severe restriction of laryngeal elevation and esophageal introitus opening that is unresponsive to physiotherapy with a speech and language therapist.

Superficial siderosis is a disease in which iron from hemoglobin is deposited in the central nervous system, resulting in conditions such as progressive sensorineural hearing loss, cerebellar ataxia, dementia, and pyramidal signs. A 30-year-old man with superficial siderosis received a cochlear implant in the left ear, which had shown complete hearing loss. Good auditory responses were obtained at 14 days after implantation. The postoperative average hearing level with the cochlear implant was 56.7 dB at 3 months and 55.0 dB at 6 months. However, the patient showed gradual hearing loss, and the dynamic range changed each time the electrode parameters were adjusted. To assess residual hearing ability, single-photon emission computed tomography was performed together with an assessment of electrical auditory brainstem response, which showed a good response and increased blood flow in both the temporal lobes. Based on this result, we asked the patient to continue using the cochlear implant to see whether a perception of speech response would be obtained. However, the patient discontinued using the cochlear implant because he could not hear satisfactorily. Hearing outcomes after cochlear implant surgery for patients with superficial siderosis are not necessarily good. Therefore, the possibility of unsatisfactory results should be fully explained before recommending this surgery to patients.

A 49-year-old Japanese man presented with a rare case of sinonasal leiomyosarcoma with left nasal bleeding for 12 months. He had no history of irradiation or malignancies, including retinoblastoma. Preoperative histological examination suggested vascular leiomyoma. Complete resection with endoscopic surgery was performed. Histological examination during the operation suggested that the tumor was a leiomyoma. However, immunohistochemical staining for α smooth muscle actin and desmin were helpful in establishing a definitive diagnosis of sinonasal leiomyosarcoma. The resection margins were positive for tumor cells. Staging with CT of the neck and thorax, ultrasound of the abdomen, and MRI of the head ruled out metastases. Second endoscopic tumor resection surgery was performed for positive resection margins. The patient's condition was successfully managed with additional excision, and he remains well with no evidence of recurrence and metastasis 36 months after treatment. Endoscopic management should be considered in suitable cases.

Gastrointestinal stromal tumors (GISTs) originate from mesenchymal cells throughout the gastrointestinal tract. A common symptom is gastrointestinal hemorrhage; intra-abdominal hemorrhage is relatively rare. There are few reports of GIST presenting with both types of hemorrhage concurrently. A 77-year-old man was admitted to our hospital because of melena and anemia (Hb: 4.7 g/dL). Computed tomography revealed a small bowel tumor and high-density fluid in both the small intestine and the pelvic floor. We diagnosed a small intestinal tumor with concurrent gastrointestinal and intra-abdominal hemorrhage, and performed emergency surgery. The tumor arose from the small intestine and was ruptured. We found hemorrhage in the pelvic cavity and performed partial small intestine resection. Pathological findings revealed that the tumor was positive for c-Kit protein and was diagnosed as GIST. The patient was discharged from the hospital on postoperative day 9 and received imatinib 1 month postoperatively. We experienced a very rare case of ruptured GIST originating from the small intestine associated with both gastrointestinal and intra-abdominal hemorrhage. We also reviewed the relevant literature.

Shoulder instability has varying mechanisms of injury, direction, and severity. Classification systems based on clustering signs and symptoms have been developed to define subgroups of shoulder instability. Despite this attempt at homogeneity, multidirectional instability (MDI) suffers from the same lack of diagnostic clarity as low back pain. In this Viewpoint, the authors outline 3 key areas to address when diagnosing MDI: patient interview, medical comorbidities, and specific shoulder tests and measures.

ObjectiveThe Lupus Foundation of America Rapid Evaluation of Activity in Lupus (LFA-REAL) clinician-reported outcome (ClinRO) and the LFA-REAL patient-reported outcome (PRO) were developed in order to capture manifestations of SLE from the perspective of both the clinician and the patient. The aim of this study is to compare the LFA-REAL ClinRO and PRO with other lupus disease activity measures.MethodsA cross-sectional analysis of patients from a single-centre cohort was performed using Spearman’s correlation. Disease activity measures included were LFA-REAL ClinRO (range 0–1400), LFA-REAL PRO (range 0–1200), Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K), clinical SLEDAI-2K and Physician Global Assessment (PGA, range 0–100).ResultsTwo hundred and twenty-seven patients with SLE were studied. The mean age was 46.3 (SD: 13.8); 212 (93.4%) were female. The mean (SD) LFA-REAL ClinRO was 25.4 (34.7), LFA-REAL PRO was 241.1 (187.6), PGA was 11.9 (15.4), SLEDAI-2K was 2.3 (3.3) and clinical SLEDAI-2K was 1.6 (2.9). The LFA-REAL ClinRO correlated with PGA (r=0.758, pConclusionsThe LFA-REAL ClinRO and the LFA-REAL PRO had good and weak correlations, respectively, with several physician-based disease activity measures in a cross-sectional study, suggesting their potential usefulness in establishing disease severity. Longitudinal studies will be required to determine their value in monitoring patients with SLE.

Carcinosarcoma is a malignant tumor composed of both epithelial and mesenchymal malignant tumor components. A 78-year-old man was transferred to our hospital because of hematemesis and tarry stool. An emergency gastrointestinal endoscopic examination revealed active bleeding from an ulcerative lesion on the posterior wall of the gastric body; endoscopic hemostasis was successfully performed. A gastrointestinal endoscopy performed two months later showed a polypoid lesion at the same place where the ulcer had been. The biopsy specimen was histologically diagnosed as well to moderately differentiated tubular adenocarcinoma. The patient underwent a laparoscopic distal gastrectomy with D2 lymph node dissection under a diagnosis of gastric adenocarcinoma. A 28 × 15 mm polypoid tumor was resected from the gastric body, and was found on microscopic examination to consist of both carcinoma and sarcoma components, showing atypical spindle cells, which were positive for α-smooth muscular actin, calponin, and h-caldesmon, but negative for CD34, CD117 (c-kit), desmin, and dog 1. These findings led to a diagnosis of gastric carcinosarcoma. The tumor was confined to the mucous membrane. Lymph node metastasis was found in one node and contained only the carcinoma component. The postoperative course was uneventful. The patient lived without recurrence for 2 years. Carcinosarcoma of the stomach is a rare tumor with high malignant potential and poor prognosis. Careful follow up is required for early detection of any recurrence.

A 66-year-old man presented at our emergency department with severe intermittent abdominal pain. His history revealed that he had eaten several mochi (rice cakes) without sufficiently chewing them before swallowing. Following computed tomography that showed a high value, he was diagnosed with an obstruction caused by mochi. Although mochi obstruction can sometimes improve with conservative treatment, this case required laparotomy. Medical literature in English on small bowel obstruction due to mochi is rare, but fortunately in this case we were able to collect complete laboratory and imaging data. Furthermore, due to the surgical findings, we could clearly diagnose the pathophysiology of mochi obstruction. Here we describe a case of small bowel obstruction due to mochi, and review the literature to determine the characteristics of intestinal obstruction caused by it.
