Abstract
PURPOSE Lenvatinib achieves favorable therapeutic outcomes for patients with radioactive iodine therapy refractory differentiated thyroid cancer (DTC); however, its use is associated with a high incidence of adverse events. To avoid severe adverse events, planned drug holidays (PDH) have been proposed. This study aimed to evaluate treatment effects, identify prognostic factors, and investigate the usefulness of PDH in patients with unresectable DTC who received lenvatinib across the multi-institutions. METHODS Fifty-one patients with unresectable DTC treated with lenvatinib were evaluated retrospectively. Overall survival (OS) and progression-free survival (PFS) were calculated, and prognostic factors were assessed. OS, PFS, and time to treatment failure (TTF) were compared between patients with and without PDH. Lenvatinib administration schedule was evaluated in PDH. RESULTS The 3-year OS and PFS rate were 53.5% and 42.1%, respectively. Multivariate analysis revealed that presence of maximum size of lung metastasis ≥10 mm was independent prognostic factor for poorer OS and PFS, and histology other than papillary thyroid carcinoma was the independent prognostic factor for poorer PFS. Twenty-five patients (49%) treated with PDH. There were significant differences in OS, PFS, and TTF between patients with and without PDH. Various schedules were used in PDH. Eight (32%) patients required switch to the different administration schedule. CONCLUSION Our results suggest that PDHs may extend OS, PFS, and TTF. In patients with PDH, various schedules used for lenvatinib administration highlight the difficulty in determining a uniform administration schedule. Therefore, it is crucial to consider the optimal lenvatinib administration schedule on a case-by-case basis.

Abstract
Carotid body tumor (CBT) is classified as a paraganglioma (PGL). Here, we report the genetic background, protein expression pattern, and clinical findings of 30 Japanese CBT cases. Germline pathogenic or likely pathogenic (P/LP) variants of genes encoding succinate dehydrogenase subunits (SDHs) were detected in 15 of 30 cases (50%). The SDHB variants were the most frequently detected, followed by SDHA and SDHD variants. One case with SDHAF2 variant was bilateral CBT, and other two multiple PGL cases were not detected P/LP variants. The three cases with germline variants that could be tested did not have somatic P/LP variants of the same genes. Immunohistochemical analysis showed negative SDHB signals in CBT tissues in five cases with germline P/LP variants of SDHB, SDHD, or SDHA. In addition, SDHB signals in CBT tissues were negative in four of nine cases without germline P/LP variants of SDHs. These findings suggest the involvement of unidentified molecular mechanisms affecting SDHs.

Abstract
OBJECTIVE The histological grade of parotid gland carcinoma (PGC) is an important prognostic factor; however, the diagnosis prior to treatment has been challenging to make. This study aimed to investigate whether the pretreatment clinical findings, including hematological inflammatory, nutritional, and immune markers, could predict the histological grade of PGC. STUDY DESIGN Retrospective study. METHODS We retrospectively enrolled 111 patients with PGC and evaluated the correlation between histological grade and pretreatment clinical findings such as age, sex, tumor staging, facial nerve paralysis, pain or tenderness, adhesion to the surrounding tissues or tumor immobility, and hematological markers. RESULTS Sixty patients (54%) were diagnosed with histological high-grade PGC. Univariate analysis revealed that age, T classification, N classification, TNM stage, facial nerve paralysis, adhesion/immobility, C-reactive protein (CRP), and CRP-to-albumin ratio (CAR) were significant predictors of PGC histological grade. On multivariate analysis, high T classification (T3, 4), high N classification (≥1), and elevated CRP (≥0.22 mg/dL) were independent predictors of high-grade PGC. CONCLUSIONS Pretreatment T classification, N classification, and CRP are significant predictors of the histological grading of PGC. Our results are useful for treatment planning and obtaining appropriate informed consent from the patients before treatment. LEVEL OF EVIDENCE 4 Laryngoscope, 2021.

Abstract
Cyclooxygenase-2 (COX-2) is one of the two isoforms of COX, an enzyme that catalyzes the conversion of arachidonic acid to prostaglandins. COX-2 is associated with the progression in various types of cancer, and its expression has been associated with a poor prognosis in head and neck squamous cell carcinoma (HNSCC). Furthermore, COX-2 expression has been associated with resistance to anticancer drugs. However, the precise mechanism of COX-2 for chemoresistance in HNSCC has not been fully elucidated. The present study aimed to investigate the effect of COX-2 on cancer stem cell (CSC) property and to reveal its effect on chemoresistance using in vitro and clinicopathological assays in HNSCC cells and tissues. The current study analyzed the immunohistochemical expression levels of COX-2 and clinicopathological factors using matched samples of pretreatment biopsy and surgical specimens from patients with hypopharyngeal carcinoma who underwent tumor resection with preoperative chemotherapy, including docetaxel. Additionally, the chemoresistance to docetaxel with or without a COX-2 inhibitor (celecoxib) was examined in HNSCC cell lines by MTS assays. To evaluate the association of COX-2 expression with stemness property, the expression levels of CSC-associated genes after exposure to celecoxib were assessed by reverse transcription-quantitative PCR. A sphere formation assay was also performed using ultra-low attachment dishes and microscopic imaging. The immunohistochemical analysis of biopsy specimens revealed a negative association between COX-2 expression in biopsy specimens and the pathological effect of induction chemotherapy in surgical specimens. The cell survival rate under exposure to docetaxel was decreased by the addition of celecoxib. COX-2 inhibition led to downregulation of CSC-associated gene expression and sphere formation. The present findings suggested that COX-2 expression may be associated with chemoresistance through the cancer stemness property, and inhibition of COX-2 may enhance chemo-sensitivity in HNSCC. Therefore, COX-2 may be an attractive target for the treatment of HNSCC.

Abstract
BACKGROUND One of the major complications in endoscopic endonasal skull base surgery (EESBS) is postoperative cerebrospinal fluid (CSF) leaks. Recently, EESBS has been applied to various skull base diseases as well as more complicated cases influenced by previous treatment with or without various comorbidities. AIMS/OBJECTIVES This study aimed to assess the factors that influence the results of postoperative CSF leak after EESBS with mixed patient backgrounds. MATERIALS AND METHODS We conducted a retrospective analysis of the clinical records of patients undergoing EESBS in our institution from 2012 to 2017. RESULTS Out of a total of 230 cases of EESBS, 11 (4.8%) suffered from postoperative CSF leakage. The rate of CSF leakage for pituitary adenoma, Rathke's cleft cyst, chordoma, and meningioma was 3.5%, 0%, 3.6% and 8.0%, respectively. Multiple variate analysis revealed that repeated surgery (p = .008) and intraoperative CSF leak (p = .044) were significant risk factors for postoperative CSF leakage. CONCLUSIONS AND SIGNIFICANCE The rate of postoperative CSF leakage in this study was comparable to previous reports, and repeated surgery may increase postoperative CSF leakage. The surgical strategy for tumor removal as well as skull base reconstruction should be given careful consideration according to tumor pathology and the patient's condition.

Abstract
Background Infected aortic aneurysm secondary to streptococcal toxic shock syndrome caused by Streptococcus pyogenes is uncommon and associated with high mortality. Case presentation A 75‐year‐old man with metastatic lung cancer and an abdominal aortic aneurysm presented with high fever for 3 days. He was diagnosed with septic shock and was admitted to our hospital. The blood culture was positive for S. pyogenes, and streptococcal toxic shock syndrome was diagnosed. During treatment, enhanced computed tomography revealed an increase in the size of the abdominal aortic aneurysm, leading to the diagnosis of an infected aortic aneurysm. Replacement of the aneurysm with a synthetic graft was carried out successfully. The patient gradually recovered after the surgery. Conclusion We successfully managed an infected aortic aneurysm secondary to streptococcal toxic shock syndrome. Infected aortic aneurysms should be considered in patients with a medical history of aortic aneurysms and presenting with streptococcal toxic shock syndrome.

Abstract
Abstract
Background: Head and Neck Squamous Cell Carcinoma (HNSCC) is the sixth most common cancer in the world. Despite the development of various treatments, the five-year survival rate for HNSCC is about 50-60% and has not been improved in recent years. Immune checkpoint inhibitors are promising, but the effect of those is limited. The development of new reagents having different mechanisms against tumor progression is still needed. From the result of drug screening, Pimozide (PMZ), an antipsychotic drug used for the treatment of schizophrenia and chronic psychosis, demonstrated a strong antitumor ability to HNSCC cells expressing high level of CD44v. In this study, we examined the combined effects of PMZ and paclitaxel (PTX) for HNSCC cells.
Methods: Using HNSCC cell lines (FaDu, Detroit562, HSC-2, OSC-19), the antitumor effects of PTX, PMZ, and the combination of PTX and PMZ were evaluated by MTS assay. Moreover, the reactive oxygen species (ROS) expression level under each drug administration was measured by flow cytometry. Moreover, PTX, PMZ (0.45mg/kg), PMZ (1mg/kg), PTX+PMZ were administered to the xenograft model by OSC-19. The tumor was resected after those treatments. The expression of CD44v, ALDH3A1, and NRF2 was evaluated by immunohistochemistry (IHC) of FFPE tissues from those extracted tumors.
Results: PMZ single-agent inhibited tumor growth in various tumor cell lines, and the
antitumor effect was enhanced by concomitant use of PTX. PMZ, which significantly increased ROS of tumor cells, was more effective than PTX in OSC-19, which was a chemoresistant cell line expressing high CD44v. Xenograft model exhibited that tumor growth was suppressed in PTX+PMZ group than in PTX and PMZ single-agent group. IHC staining revealed that PMZ administration restrained CD44v expression, and ALDH3A1 expression markedly decreased in PMZ treated tumors, but not in PTX treated tumors.
Conclusions: PMZ dramatically induced ROS production in tumor cells. These data suggest that aldehyde produced by ROS might suppress HNSCC tumor growth. The results from this study indicated that PMZ could be a novel therapeutic reagent for HNSCC in combination with existing anticancer drugs.

Abstract
Objective Previous studies have evaluated various markers as prognostic predictors in patients with many types of cancers. However, the influence of such factors on the outcomes of patients with parotid gland carcinoma (PGC) is unknown. This study investigated the roles of alternative markers in the prognoses of patients with PGC. Methods Overall, 101 patients who underwent curative treatment for PGC were retrospectively evaluated, and their 5‐year overall and disease‐free survival rates were calculated. The prognostic values of clinical and pathologic factors were determined. Results The 5‐year overall and disease‐free survival rates were 73.1% and 62.8%, respectively. Multivariate analysis revealed that a low lymphocyte‐to‐monocyte ratio (LMR), high T classification, high N classification, and perineural invasion were independent predictors of poor prognosis. Conclusions Thus, we identified LMR as an independent prognostic factor for patients with PGC. Patients with low LMRs who are amenable to treatment may require adjuvant treatment to improve their prognoses. Level of Evidence 4 Laryngoscope, 131:E864–E869, 2021

Abstract
Cyclooxygenase-2 (Cox-2) has been shown to promote cancer initiation and progression through pleiotropic functions including induction of epithelial-to-mesenchymal transition (EMT) via its predominant product prostaglandin E2 that binds to the cognate receptor EP2. Hence, pharmacological inhibition at the level of EP2 is assumed to be a more selective alternative with less risk to Cox-2 inhibition. However, little is known regarding the anti-cancer effect of an EP2 antagonist on the malignant properties of cancers including hypopharyngeal squamous cell carcinoma (HPSCC). The present study found that both the Cox-2 inhibitor celecoxib and the EP2 antagonist PF-04418948 upregulated CDH-1 expression, restored membranous localization of E-cadherin, and reduced vimentin expression, by downregulating the transcriptional repressors of E-cadherin in BICR6 and FaDu cells. Such Cox-2 or EP2 inhibition-induced EMT reversal led to repressed migration ability in both cells. Immunohistochemical analysis of surgical HPSCC specimens demonstrated an inverse relationship in expression between Cox-2 and E-cadherin both in the context of statistics (P = 0.028) and of reciprocal immunolocalization in situ. Multivariate logistic regression revealed that overexpression of Cox-2 (P < 0.001) and downregulation of E-cadherin (P = 0.016) were both independently predictive of neck metastasis. These results suggest that suppression of cell migration ability via reversing EMT by inhibiting the Cox-2/EP2 signaling may contribute to preventing the development and progression of lymphatic metastasis. Collectively, targeting Cox-2/EP2, especially using EP2 antagonist, can be a promising therapeutic strategy by exerting an anti-metastatic effect via EMT reversal for improving the treatment outcomes of patients with various cancers including HPSCC.

Abstract
BACKGROUND This study aimed to investigate p16 and COX2 expression in oropharyngeal squamous cell carcinoma (OPSCC), and evaluate the prognostic role of COX2 expression under the new TNM classification. MATERIALS AND METHODS Biopsy specimens obtained from 75 patients with OPSCC were stained for p16 and COX2 expression immunohistochemically. The results and clinical records were analyzed retrospectively. RESULTS Fifty-nine patients (79%) were positive for p16. COX2 expression was correlated with poor relapse-free survival in patients overall, and in p16-positive patients. Smoking was positively associated with COX2 expression. Moreover, both positive COX2 expression and anterior wall tumor subsite were independently correlated with lymph node metastasis, which was the only independent prognostic factor in p16-positive OPSCC. CONCLUSION The p16-positive rate in this study was comparable with that in the USA and Europe, and higher than that in other Asian countries. COX2 expression might affect the prognosis of p16-positive OPSCC through promoting lymph node metastasis.

Abstract
Abstract
Introduction: COX-2 is one of the two isoforms of cyclooxygenase, an enzyme that catalyzes the conversion of arachidonic acid to prostaglandins. COX-2 is considered to be associated with progression in various cancers, and its expression has been reported to have an impact on poor prognosis in head and neck squamous cell carcinomas (HNSCCs). Furthermore, COX-2 expression has been shown to be associated with resistance to anticancer drugs. However, the precise mechanism of COX-2 for chemoresistance in HNSCC is not fully elucidated. The aim of the present study was to investigate the impact of COX-2 on cancer stem cell property, and to reveal its effect on chemoresistance by in vitro and clinicopathological assays. Methods: We examined the chemoresistance to docetaxel with or without COX-2 inhibitor (celecoxib) in HNSCC cell lines (FaDu, Detroit512) by MTS assays. To evaluate the association of COX-2 expression with stemness property, we assessed alteration of expression levels of the genes related to cancer stem cell (CSC) property after exposure to celecoxib by quantitative real-time PCR. We also performed a sphere formation assay using ultra low attachment dishes and microscopic imaging. Moreover, we analyzed immunohistochemical expressions of COX-2 and clinicopathological factors by using matched samples of pre-treatment biopsy and surgical specimens from hypopharyngeal carcinoma patients who had undergone trans-oral tumor resection with preoperative induction chemotherapy including docetaxel. Results: Cell survival rate under exposure to docetaxel was decreased by addition of celecoxib. COX-2 inhibitor downregulated the expression of Oct3/4 and Nanog. Sphere formation was inhibited by co-culture with COX-2 inhibitor, especially in FaDu cells. Immunohistochemical study in biopsy specimens revealed a negative correlation between COX-2 expression in biopsy specimens and pathological effect of induction chemotherapy in surgical specimens. Conclusion: The present study suggests that COX-2 expression is associated with cancer stemness property, and inhibition of COX-2 has a possibility to enhance chemosensitivity in HNSCCs. Furthermore, initial COX-2 expression in biopsy specimens may predict the effect of chemotherapy in HNSCCs. These results indicate that COX-2 can be an attractive target for the treatment of HNSCC.

Abstract
This paper presents an extremely rare case of synovial sarcoma arising from the maxillary sinus, which resulted in a clinically complete response to chemotherapy. Synovial sarcoma is a rare soft tissue malignant tumor, most commonly affecting the extremities. While ~10% occur in the head and neck region, synovial sarcoma of the sinonasal tract is extremely rare, with only 11 cases having been reported previously. As with other sarcomas, the standard treatment is complete resection while allowing for a safe margin, but this is often difficult in the head and neck area due to the complicated anatomy there. This makes the treatment of head and neck sarcoma challenging and leads to the need for a multimodal approach in advanced cases. However, the exact efficacy of chemotherapy is not well understood. In this report, we present a case of unresectable maxillary sinus synovial sarcoma that was successfully treated by chemotherapy followed by radiation therapy. A 53-year-old Japanese man was referred to our hospital with a history of left nose obstruction over the previous couple of years. Computed tomography/magnetic resonance imaging revealed a tumor arising from the maxillary sinus that extended to adjacent tissues. A biopsy was performed, and the tumor was diagnosed as synovial sarcoma. Since the tumor was unresectable, neoadjuvant chemotherapy was administered. The response was excellent, and the tumor became undetectable under endoscopy and radiological imaging. This provided us with a clinical evaluation of “complete response”. The treatment was concluded with definitive radiotherapy and two more cycles of adjuvant chemotherapy. The patient remains free of disease 12 months after treatment. Synovial sarcoma of the head and neck is a rare entity; complete resection is the treatment of choice but (neo)adjuvant chemotherapy can be considered in unresectable cases, as we show here in the present case.

Abstract
Abstract
Background: Overexpression of cyclooxygenase 2 (Cox-2), an inducible prostaglandin (PG) synthetase, is assumed to promote cancer progression through its multifaceted function, including induction of angiogenesis, stimulation of cell proliferation, restraint on apoptosis, and immunosuppression. Furthermore, recently its inverse relationship with E-cadherin expression was reported. The epithelial-to-mesenchymal transition (EMT) accompanied by the downregulation of E-cadherin is supposed to promote metastasis. However, neither the anti-cancer effect of selective Cox-2 inhibitors on the regulation of E-cadherin nor its specific mechanism has been examined in pharyngeal squamous cell carcinoma (PhSCC). In addition, the anti-tumor effect of EP2 antagonist, a possibly more selective inhibitor of PGE2, remains to be elucidated.
Methods: We used quantitative real-time PCR to examine the effects of a selective Cox-2 inhibitors, Celecoxib, and a selective EP2 antagonist, PF-04418948, on the gene expressions of CDH-1, its transcriptional repressors (snail, ZEB1, twist), and vimentin in the human PhSCC cell lines BICR6 and FaDu. Alteration in E-cadherin expression on the cell surface was evaluated by immunofluorescent staining. In vitro proliferation and migration assays were performed to assess cellular behaviors. Clinicopathological factors and immunohistochemical expressions of Cox-2 and E-cadherin were evaluated using surgical specimens from 54 patients with PhSCC who underwent transoral resection.
Results: Both Celecoxib and PF-04418948 upregulated the CDH-1 expression and the membranous E-cadherin expression and downregulate the vimentin expression in the PhSCC cells through the suppression of snail, ZEB1, and twist expression. The extent of this effect depended on the baseline expression levels of both E-cadherin and Cox-2 in each cell line. Additionally, the cell migration was attenuated by both Celecoxib and PF-04418948, whereas the cell proliferation was not affected. Univariate analysis showed that differentiation, overexpression of Cox-2, and decreased expression of E-cadherin were significantly correlated with lymph node metastasis. Multivariate logistic regression revealed that overexpression of Cox-2 (odds ratio [OR]=53.49, P<0.001) and decreased expression of E-cadherin (OR=0.06, P=0.016) were the independent risk factors affecting lymph node metastasis.
Conclusions: These findings suggest that the appropriately selective administration of the Cox-2 inhibitor and EP2 antagonist may have an anti-metastatic effect through suppression of EMT by restoring E-cadherin expression. In addition, overexpression of Cox-2 and downregulation of E-cadherin may be closely implicated in lymph node metastasis in PhSCC.

Abstract
Abstract
Introduction: Tumor hypoxia is considered to be associated with progression in various cancers. Hypoxia inducible factor-1α (HIF-1α) is one of the molecules which play a key role in tumor hypoxia. High HIF-1α expression is reported to have an impact on poor prognosis and resistance to chemotherapy or radiotherapy in head and neck squamous cell carcinoma (HNSCC). However, the effect and mechanism of HIF-1α on tumor metastasis in HNSCC is still unclear. The aim of the present study was to investigate the molecular targets of HIF1-α relevant to metastasis, and to reveal the impact of HIF1-α on HNSCC metastasis by using clinicopathological assays. Methods: The cell proliferation rate with or without HIF-1 inhibitor (KC7F2) in HNSCC cell lines (FaDu, Detroit512) was evaluated by MTS assay. Gene expression levels related to epithelial-mesenchymal transition (EMT), cancer stem cell (CSC) and HIF-1α in each HNSCC cell lines were measured by quantitative real-time PCR. Immunohistochemical expressions of HIF-1α and clinicopathological factors were analyzed using surgical specimens from 33 patients with hypopharyngeal carcinoma who had undergone trans-oral tumor resection without previous chemotherapy nor radiotherapy.
Results: HIF-1 inhibitor suppressed the cell growth of HNSCC cell lines in a dose dependent manner. HIF-1 inhibitor downregulated the expression of HIF-1α, twist, Oct3/4 and Nanog. In immunohistochemical study, the HIF-1α expression was higher in cancer cells than in normal cells of the adjacent normal mucosa. Univariate analysis revealed that high expression of HIF-1α was significantly correlated with T-classification (P=0.012), lymph node metastasis (P=0.002) and lymphatic invasion (P=0.03).
Conclusion: These results suggest that HIF-1α plays a key role in tumor progression of HNSCC through EMT and CSC properties. From the present study, HIF-1α inhibition may have the possibility to suppress tumor metastasis, making HIF-1α an attractive target for the treatment of HNSCC.

Abstract
Background Transoral videolaryngoscopic surgery (TOVS) was developed as a new distinct surgical procedure for hypopharyngeal cancer (HPC) and supraglottic cancer (SGC) staged at up to T3. However, long-term treatment outcomes of TOVS remain to be validated. Methods Under a straight broad intraluminal view provided by combined use of a distending laryngoscope and a videolaryngoscope, we performed en bloc tumor resection via direct bimanual handling of the ready-made straight-form surgical instruments and devices. We retrospectively analyzed functional and oncologic outcomes of 72 patients with HPC (n = 58) or SGC (n = 14) whose minimum follow-up was 24 months or until death. Results The cohort comprised nine patients of Tis, 23 of T1, 33 of T2, and 7 of T3. Among 36 patients (50%) who underwent neck dissection simultaneously, all but one were pathologically node-positive. Twelve patients underwent postoperative concurrent chemoradiation (CCRT) as adjuvant treatment, and another four patients underwent radiation or CCRT for second or later primary cancer. The endotracheal tube was removed in an operation room in all but two patients who underwent temporary tracheostomy. Pharyngeal fistula was formed transiently in two patients. The median time until patients resumed oral intake and could take a soft meal was 2 and 5 days, respectively. Eventually, 69 patients (96%) took normal meals. The 5-year cause-specific survival (CSS), overall survival (OS), larynx-preserved CSS, and loco-regional controlled CSS were 87.3%, 77.9%, 86.0%, and 88.0%, respectively. Multivariate analysis revealed N2-3 as an independent prognostic factor in both CSS (hazard ratio [HR] = 25.51, P = 0.008) and OS (HR = 4.90, P = 0.022), which indirectly reflected higher risk of delayed distant metastasis. Conclusions Considering its sound functional and oncological outcomes with various practical advantages, TOVS can be a dependable, less invasive, and cost-effective surgical option of an organ-function preservation strategy for HPC and SGC.

Abstract
Conclusion The sigmoid-incision (S-I) rescue flap technique has the advantage of both reduced-invasiveness and providing a sufficient surgical corridor for endoscopic endonasal skull base surgery (EESBS). Objective Skull base reconstruction with nasoseptal flap (NSF) is critically important in managing post-operative cerebrospinal fluid (CSF) leakage after tumor removal by EESBS. The NSF needs to be elevated before sphenoidotomy and posterior septectomy to preserve the pedicle. However, most extradural surgery without CSF leakage does not require NSF and, therefore, NSF preparation is often futile. As a result, a rescue flap technique to overcome this problem has been developed, whereby a new S-I rescue flap method is used that enables wide exposure of the sphenoidal rostrum and smooth manipulation of surgical instruments to preserve the NSF pedicle. Materials and methods Starting in April 2014, 19 cases underwent EESBS with S-I rescue flap. Results All patients underwent tumor resection under an adequate operative field with smooth manipulation of surgical instruments. Two complications were experienced. One patient had CSF leak after removal of the nasal packing, but the leakage was successfully closed by conventional NSF. Another patient had epistaxis from the septal wall, but this was controlled by electrocautery.

Abstract
A 32-year-old female presented with a history of intermittent, severe lower back pain, exacerbated by pregnancy and persisting for several years. Magnetic resonance (MR) imaging showed a sacral mass as a low signal intensity area on the T1-weighted image and a high signal intensity area on the T2-weighted image, consistent with a cystic structure containing cerebrospinal fluid. A tethered cord attached to the thecal sac was also confirmed. Sacral laminectomy revealed thinned sacral vertebral laminae, but no neuronal elements existed within the cyst. The cyst was attached to the distal thecal sac by a small fistula. The thecal sac was explored, revealing a thick filum terminale, which was transected. The severe pain resolved postoperatively. This type of meningeal cyst, often called "occult intrasacral meningocele," is best diagnosed by MR imaging. Surgery to obliterate the fistulous tract is the optimum treatment. Total removal of the cyst is unnecessary, but evaluation of other associated congenial abnormalities is important.

Abstract
The maximum ouabain binding capacity in erythrocytes from 8 normal subjects and 14 patients with hyperthyroidism was assessed by measuring [3H]-ouabain binding. The mean value for maximum ouabain binding capacity was significantly lower in the patients than in normals (0.422 +/- 0.084 vs 0.671 +/- 0.095 pmol per 10(9) cells, p less than 0.001). Furthermore, a close inverse correlation was found between the ouabain binding capacity and serum T3 (r = 0.766; p less than 0.01) or T4 (r = -0.870; p less than 0.001) levels. These results suggest that the maximum ouabain binding capacity in erythrocytes may provide a useful index of the peripheral effect of thyroid hormone.
