8257 Pancreatic Neuroendocrine Tumor Presenting As Carcinoid Syndrome

Abstract Disclosure: D. Phung: None. Introduction Pancreatic neuroendocrine tumors (NETs) are rare tumors that arise in neuroendocrine cells of the pancreas. These tumors secrete a wide array of hormones. Carcinoid syndrome is a result of well-differentiated neuroendocrine tumors that secrete biologically active amines and peptides that cause the clinical manifestation of flushing, diarrhea, cardiac involvement, and wheezing. Case Presentation A 57-year-old male presented to the clinic for symptoms of tachycardia, shortness of breath, dizziness, and sweating for the past year. He had past medical history of chronic kidney disease, history of previous cardiac arrest, history of previous myocardial infarction, congestive heart failure, hypertension and gastric reflux disease. No history of tobacco, alcohol, or drug consumption. No previous surgeries. Family history with heart disease and prostate cancer in his father. His symptoms began over the course of the past year. Initially began with shortness of breath, chest pain, weight gain which then developed into dizziness with standing, episodes of night time sweating. He had associated headaches that were occurring daily. Vomiting would occur intermittently three to four times weekly. He noted episodes of flushing with rash occurring in the upper chest and bilateral arms. Diarrhea and loose bowel movements would occur occasionally. On examination he had tachycardia with heart rate at 103 BPM. Lung fields clear throughout. Abdomen was soft, nontender, without masses palpated. On biochemical testing chromogranin A was highly elevated and remained elevated upon repeat testing. Initial imaging with CT abdomen and pelvis with contrast was negative. PET scanning confirmed and localized his NET, revealing increased tracer uptake and hypervascularity in the neck of pancreas as well as two regions in the right lower lobe of the liver. Following confirmation and localization of his tumor he was then referred for surgical evaluation and treatment. Discussion In our presented case, the patient presented with symptoms suggestive of carcinoid syndrome which was confirmed biochemically with elevated chromogranin A. Clinical suspicion remains critical in diagnosis of NETs. The patient presented with clinically suspicious carcinoid syndrome, but initial testing with CT scan was negative and required further PET-based tracing to uncover tumors. Our case highlights the importance of clinical examination and acumen in diagnosing neuroendocrine tumors. Presentation: 6/2/2024

6810 Successful Insulin Allergy Desensitization To Humalog During The Second Trimester Of Pregnancy

Abstract Disclosure: J. Noreña: None. S. Seav: None. S. Jiang: None. S. McGhee: None. M. Tan: None. M. Basina: None. Background: Insulin allergy is rare, occurring in only 0.1 to 3% of people with insulin-treated diabetes. During pregnancy, this incidence is even lower due to a relative immunosuppressive state. Currently, there are no standardized insulin allergy desensitization protocols for this specific patient population. Clinical Case: A 39-year-old female (G4P3003) with T2DM and multiple prior medication allergies presented to the antepartum unit in her 17th week of pregnancy due to hyperglycemia and reported insulin allergy to NPH insulin.Patient was initially diagnosed with gestational diabetes during her third pregnancy, requiring NPH insulin which she seemed to tolerate well at the time. She remained medication-free for two years post-delivery but later developed T2DM with an A1c of 6.8%. Metformin and Jardiance, previously prescribed, were discontinued upon confirmation of her current pregnancy. She opted to manage her diabetes through diet and exercise alone, but her A1c rose to 7.0%, prompting the initiation of NPH.Following the first dose of NPH at home, she experienced a localized burning sensation at the injection site associated with facial flushing, followed by a diffuse, pruritic, erythematous rash on her face, chest, abdomen, and bilateral arms. Due to her history of anaphylaxis to other drugs (mainly antibiotics), she was admitted to the hospital for monitoring. Inpatient attempts with lower doses of NPH and then a trial of glargine triggered new rash episodes. Work-up revealed negative insulin antibodies, low IgG, and a normal CBC. She was started on Humalog to cover basal dose administered every 6 hours and additional prandial injections, which she tolerated prior to discharge. One week later, she developed a new local erythematous reaction at the Humalog injection site followed by a generalized rash which led to her readmission.Allergy was consulted and facilitated a successful desensitization protocol to Humalog. The protocol included escalating doses of insulin administered every 30 minutes (0.1u, 0.2u, 0.4u, 0.8u, 1u, 2u, 3u, 3u) to achieve a pre-determined cumulative dose of 10.5 units. Patient tolerated the protocol well and was discharged with q6h Humalog for basal coverage in addition to prandial doses with plan to transition to insulin pump therapy with Humalog soon. Conclusion: This unique case demonstrates how insulin desensitization can be a safe and successful strategy to help achieve insulin tolerance and glycemic control during pregnancy. Election of an insulin, such as Humalog, that can achieve the one-hour post-prandial glucose target during pregnancy and also provide effective basal coverage should be considered as desensitization can only be done with one insulin type at a time.

14-month-old female with anti-MDA5 juvenile dermatomyositis complicated by liver disease: a case report

BackgroundJuvenile Dermatomyositis (JDM) is a rare disorder with subtypes associated with different myositis-specific antibodies (MSAs) including anti-MDA5. Hepatic involvement in JDM is rare and has not previously been documented in anti-MDA5 JDM. There is a lack of formal research on treatment protocols for anti-MDA5 JDM, though tofacitinib is a highly regarded emerging therapy.Case presentationA previously healthy 14-month-old Hispanic female presented to a pediatric rheumatology clinic with eight months of worsening rash, weakness, periorbital edema, intermittent fevers, and weight loss. Her physical exam was notable for fever, thinning of hair, heliotrope rash, periorbital edema, violaceous macules on her bilateral elbows, forearms, arms, and knees, arthritis, Gottron’s sign, and hepatomegaly. The patient was admitted, and symptoms progressed to include hypoxemia. Subsequent workup was notable for ground glass opacities of bilateral lung fields on chest CT, myositis visualized on MRI and confirmed with muscle biopsy, and liver biopsy showing nonspecific signs of liver injury. After a thorough infectious disease workup to rule out concomitant infection, the patient was started on high-dose steroids and induction with cyclophosphamide. She responded well with disease remission maintained with tofacitinib in the outpatient setting.Discussion and conclusionsOur patient is notable due to her young age at presentation, histopathologically confirmed liver injury, and response to treatment. The case adds to the growing body of literature supporting tofacitinib for anti-MDA5 JDM in the pediatric population. Future research can better standardize effective treatment protocols and define the mechanism of liver involvement. For patients with nonspecific liver injury, muscular, and cutaneous disease, anti-MDA5 JDM should be considered in the differential diagnosis with treatment options including tofacitinib for confirmed cases.

Research on the Human Motion Recognition Method Based on Wearable.

The accurate analysis of human dynamic behavior is very important for overcoming the limitations of movement diversity and behavioral adaptability. In this paper, a wearable device-based human dynamic behavior recognition method is proposed. The method collects acceleration and angular velocity data through a six-axis sensor to identify information containing specific behavior characteristics in a time series. A human movement data acquisition platform, the DMP attitude solution algorithm, and the threshold algorithm are used for processing. In this experiment, ten volunteers wore wearable sensors on their bilateral forearms, upper arms, thighs, calves, and waist, and movement data for standing, walking, and jumping were collected in school corridors and laboratory environments to verify the effectiveness of this wearable human movement recognition method. The results show that the recognition accuracy for standing, walking, and jumping reaches 98.33%, 96.67%, and 94.60%, respectively, and the average recognition rate is 96.53%. Compared with similar methods, this method not only improves the recognition accuracy but also simplifies the recognition algorithm and effectively saves computing resources. This research is expected to provide a new perspective for the recognition of human dynamic behavior and promote the wider application of wearable technology in the field of daily living assistance and health management.

Quantity versus Quality: Chlorhexidine Bathing Adequacy Assessments in 3 High-Risk Units

Background: Chlorhexidine gluconate bathing (CHGB) prevents healthcare associated infections (HAIs). CHGB quality is rarely assessed; prior studies identified that concentrations of CHG can be suboptimal, particularly at the neck, and if rinsed after application. In the setting of increased HAI rates on 3 high-risk units, we evaluated CHG skin concentrations, comparing results to bathing documentation and patient reports as part of a quality improvement initiative. Methods: All patients admitted to 3 high-risk units were swabbed for CHG concentration testing at the neck, bilateral upper arms, and groin. Swabs were processed using a semi-quantitative colorimetric CHG assay. A threshold of 0.001875% CHG was used to determine adequacy based on prior studies. Adequacy was assessed by body site, timing of bath, and patient-reported skin care activities using Chi-square tests in SAS 9.4. Per hospital policy, all admitted patients are bathed daily with 2% CHG pre-packed wipes. Patients without a documented CHGB for the duration of the admission were excluded. Results: CHG testing was completed on 63 patients: 23 on medical ICU, 18 surgical ICU, 22 oncology ward, yielding 249 samples. Only ward patients could report the time of last CHGB, which agreed with nursing documentation for 12/21(57%) Adequacy by sample was no different across units: 59/88(67%) Oncology, 68/90(76%) MICU, 56/71(79%) SICU, p=0.2091. Site adequacy was different by site: neck 36/63(57%), left arm 49/62(79%), right arm 50/62(81%), groin 48/62(77%), p=0.0083. Samples taken from the 11 patients with > = 24 hours since last CHGB were more likely to be below threshold concentration: 19/47(40%) versus 47/202(23%) not adequate in the recent treatment grouping. Three patients reported showering soon after the CHGB and 8 patients used moisturizing lotion. The percent of samples below threshold for the showering patients (6/12, 50%) and lotion-users (11/32, 34%) were not significantly different from the non-showering or non-lotion using patient samples (p=0.0588 and 0.2800 respectively). Conclusion: In a facility with longstanding daily CHGB policies in place, 66/249 samples from 63 patients lacked adequate concentrations of CHG for optimal HAI prevention. Even in patients with recent CHGB, 23% of sites tested revealed inadequate levels of CHG, while 60% of those overdue for CHGB kept adequate concentrations. Reliable implementation strategies are required for CHGB so as to ensure maximal infection prevention impact.

Admission Left-Arm Systolic Blood Pressure and In-Hospital Mortality After Acute Type A Aortic Dissection Repair

Admission systolic blood pressure is a significant predictor of in-hospital mortality in patients with acute type A aortic dissection (ATAAD). While previous studies have focussed on recording the highest blood pressure value from both arms, this study aimed to evaluate the associations between blood pressure in bilateral arms and in-hospital mortality. Data were analysed from 262 patients with ATAAD treated at a single centre. The relationship between bilateral arm blood pressure upon admission and in-hospital mortality was assessed in a logistic regression model. To comprehensively evaluate potential non-linear relationships, the association between admission bilateral systolic blood pressure (SBP) and the risk of in-hospital mortality was analysed using restricted cubic splines on a continuous scale. Mean age was 53.6±12.5 years and 194 (74.0%) were male. Baseline and operative data showed that ages, body mass index, smoking, left-arm SBP, left-arm diastolic blood pressure (DBP), right-arm SBP, right-arm DBP, syncope, cerebral/cardiac ischaemia, retrograde brain perfusion, Bentall procedure, coronary artery bypass grafting, and aortic valve replacement significantly differed among the left-arm SBP tertiles. In-hospital mortality was 17.6% (46 of 262). Restricted cubic splines demonstrated that the relationship between presenting left-arm SBP and in-hospital mortality followed a U-shaped curve, whereas non-linearity was not detected in the right arm. This study found a U-shaped association between admission left-arm SBP and in-hospital mortality in ATAAD surgery patients, whereas a non-linearity relationship was not detected for right-arm SBP. Low left-arm SBP independently correlated with increased in-hospital mortality, underscoring the significance of bilateral blood pressure differences in ATAAD prognosis.

Suspected duloxetine-induced restless legs syndrome phenotypic variant: a case report

BackgroundRestless arms syndrome (RAS) is the most common variant of restless legs syndrome (RLS), which is easy to be ignored in clinical practice due to the lack of specific diagnostic criteria. When effective therapeutic agents induced RAS and symptoms persisted after briefly observation, clinicians will face the challenge of weighing efficacy against side effects.Case presentationA 67-year-old woman was admitted to a geriatric psychiatric ward with depression. Upon admission, the escitalopram dose was reduced from 15 mg to 10 mg per day, and the duloxetine dose was increased from 60 mg to 80 mg per day. The next night before bedtime, she developed itching and creeping sensations deep inside bilateral shoulders and arms, with the urge to move, worsening at rest, and alleviation after hammering. The symptoms persisted when escitalopram was discontinued. A history of RLS was confirmed. Treatment with 40 mg of duloxetine and 0.125 mg of pramipexole significantly improved depression, and the paresthesia disappeared, with no recurrence occurring 6 months after discharge.Discussion and conclusionsThis case suggests that psychiatrists should pay attention to RLS variants when increasing doses of duloxetine. Long-term improvement can be achieved through dosage reduction combined with dopaminergic drugs instead of immediate discontinuation.

High-Definition Liposuction Contouring of the Arms in Males and Females

Liposuction is one of the most common esthetic procedures performed in both males and females. High-definition liposuction has become more sought after recently, especially to define the arms and abdominal musculature. This is a case report of high-definition liposuction of the arms to create markings and techniques to obtain a muscular and sculpted appearance of the arms. Between July 2022 and October 2023, 6 patients were selected for high-definition liposuction to bilateral arms. Specific pre-operative markings were made to outline the deltoid, biceps, and triceps. Traditional liposuction with focus on liposculpture of these markings was done to define the muscles of the arms. Results showed that with proper selection, pre-operative markings, and adequate technique of liposculpture, the muscles of the arms can be defined to meet patient expectations and give a more athletic appearance.

New confidence-building measures can reduce tensions around subcritical tests

ABSTRACT With rising tensions between the United States on one side, and China and Russia on the other, the three countries have grown mutually accusatory about some testing activities they conduct to maintain and modernize their nuclear arsenals, with allegations made by the United States focusing on very low-yield fission experiments. In a world where trust in the nonproliferation regime is weakening and most bilateral arms control measures have been suspended, many experts fear that recriminations over very low-yield tests could spark a new escalation spiral to full-scale nuclear tests. Transparency measures could diffuse the suspicions around these tests and strengthen the Comprehensive Nuclear Test Ban Treaty, which is largely being complied with but still not legally in force.

3D Topographical Scanning for the Detection of Osteoporosis.

Osteoporosis is associated with greater risk of fracture, which can lead to increased morbidity and mortality. DEXA scans are often inaccessible for patients, leaving many cases of osteoporosis undetected. A portable 3D topographical scan offers an easily accessible and inexpensive potential adjunct screening tool. We hypothesized that 3D scanning of arm and calf circumference and volume would correlate with DEXA T-scores. 96 female patients were enrolled. Patients were consented and completed a topographical scan of bilateral arms and lower legs with a mobile 3D scanner for arm and calf circumference and volume in clinic. Patient charts were then retrospectively reviewed for DEXA T-scores. Forearm DEXA T-score was positively correlated with arm circumference (r = 0.49, p<0.01), arm volume (r=0.62, p<0.01), and calf volume (r=0.47, p<0.01). Femoral neck DEXA T-score was positively correlated with calf circumference (r=0.36, p<0.01) and calf volume (r=0.36, p<0.01). Our results showed significant correlations between DEXA T-scores and topographical measurements from mobile device acquired 3D scans, although these were in the "moderate" range. Mobile device-based 3D scanning may hold promise as an adjunct screening tool for osteoporosis when DEXA scanning is not available or feasible for patients, although further studies are needed to elucidate the full potential of its clinical utility. At a minimum, identifying a patient as high risk may promote earlier diagnostic DEXA scanning.

Malignancy smells in the air: widespread eroded, hemorrhagic, and lichenified plaques in an older man

Paraneoplastic pemphigus (PNP) is a rare autoimmune mucocutaneous disease associated with underlying neoplasia. It is typically characterized by painful mucosal erosions and dark, patchy skin eruptions. A 66-year-old male was admitted to the internal medicine outpatient clinic with complaints of suddenly started rashes, loss of appetite, dyspepsia, weakness, and unexplained gross weight loss. The patient was cachectic and physical examination revealed widespread eroded, erythematous, thick-middle, yellow-pitted, lichenified plaques on bilateral arms and legs and the hands and feet dorsum. Scattered seborrheic keratosis lesions on the trunk were also detected. He had microcytic anemia with elevated CA 19-9 measures. Abdomen computed tomography showed a malignant mass in the antrum. Endoscopic biopsy of the gastric mass revealed poorly differentiated adenocarcinoma composed of discohesive signet ring cells and skin punch biopsy was compitable with paraneoplastic pemphigus.&#x0D; In patients with rapidly developing skin lesions with constitutional symptoms, underlying malignancies should be kept in mind.

Quantifying Patient-Initiated Upper Extremity Movement After Surgical Reconstruction for Adult Pan-Brachial Plexus Injury.

Determining functional recovery in adult patients with traumatic pan-brachial plexus injury (pBPI) is hampered by the fact that most outcome measures are collected in the clinical setting and may not reflect arm use in the real world. This study's objectives were to demonstrate the feasibility of using wearable motion sensor technology to quantify spontaneous arm movement in adult patients with pBPI after surgical reconstruction and report the time and intensity with which the affected arm was used. Twenty-nine patients with pBPI who underwent surgical reconstruction at least 2 years prior were included in this study. Study participants wore an accelerometer on bilateral arms for 7 days. The vector time (VT) and magnitude with which each arm moved were collected and divided by the same values collected from the uninjured arm to generate a ratio (VT and vector magnitude [VM], respectively) to quantify differences between the arms. Correlations between VT, VM, and patient demographic and physician-elicited clinical measures were calculated. Patients were enrolled at Chang Gung Memorial Hospital, Linkou Medical Center, Taiwan, and data analysis was performed at the University of Michigan. Twelve patients had pan-avulsion injuries, and 17 patients had C5 rupture with C6-T1 avulsion injuries. All underwent nerve reconstruction with contralateral C7 or ipsilateral C5 nerve roots as donors. At mean 7.3 years after surgery, the mean VT ratio was 0.54 ± 0.13 and the mean VM ratio was 0.30 ± 0.13. Both VT and VM ratios were significantly correlated with patient employment and movements at the elbow and forearm. Wearable motion detection technology can capture spontaneous, real-world movements of the arm in patients who have undergone surgical reconstruction for pBPI. Despite severe injuries, these patients are able to use their affected arm 50% of the time and with 30% of the intensity of their unaffected arm, which is positively correlated with return to work after injury. These data support the use of surgical reconstruction for pBPI.

Does Botulinum Toxin Injection Exacerbate Sarcopenia and Bone Mass in Individuals With Cerebral Palsy?

BackgroundBotulinum toxin (BoNT) causes sarcopenia and low bone mass in animal studies. Whether such effect exists in children and adolescents with spastic cerebral palsy (CP) is not clear yet. To investigate the influences of BoNT on grip strength (GS), skeletal muscle mass, and bone mineral density (BMD) in children and adolescents with spastic CP, we conducted this uncontrolled longitudinal study. MethodsThe body composition of individuals with spastic CP were measured by dual-energy X-ray absorptiometry at preinjection and at 12 and 24 weeks after BoNT intervention. Sarcopenia was defined as meeting both decreased GS and low muscle mass. Twenty-five participants were enrolled (mean age 8.5 years). ResultsBefore BoNT intervention, four adolescents had sarcopenia and low bone mass. When the body composition was analyzed as four limbs, trunk, and head, the skeletal muscle mass of the injected limbs, appendicular skeletal muscle mass, and total body less head BMD increased significantly over 24-week follow-up period (P = 0.0117, 0.0032, 0.0229), whereas the GS remained unchanged. When the body composition was analyzed as segments derived from bilateral arms, forearms, hands, thighs, and lower legs, the skeletal muscle mass (P = 0.0113) but not BMD of the injected segments increased significantly over the 24 weeks. The prevalence of low muscle mass, decreased GS, sarcopenia, and low bone mass did not change over 24 weeks. ConclusionsThe present study showed that BoNT does not exacerbate sarcopenia and low bone mass in individuals with spastic CP.

84-Year-Old Female With Easy Bruising

An 84-year-old female presented to the primary care clinic with easy bruising that began approximately 3 months prior. At that time, she noticed a large spontaneous ecchymosis on her left arm. Over the following weeks, she developed atraumatic ecchymoses over the bilateral arms, legs, abdomen, and back. She denied epistaxis, gingival bleeding, or difficulty achieving hemostasis. Review of systems was positive for 15 kg unintentional weight loss over the preceding year, which was corroborated by clinic weights. She denied fevers, night sweats, lymphadenopathy, fatigue, myalgias, chest pain, dyspnea, hematemesis, hemoptysis, hematuria, hematochezia, or melena. CORRECT ANSWERS: 1. e. 2. a. 3. d. 4. e. 5. b.

Bilateral tonic seizures vs. bilateral tonic events in critically ill patients: differences in semiology

PurposeOur primary aim was to analyze bilateral epileptic tonic seizures (ETS) and bilateral non-epileptic tonic events (NTE) in critically ill patients. Our secondary aim was to analyze ETS per their epileptogenic zone. MethodsWe performed a retrospective analysis of clinical signs in patients with bilateral ETS and NTE. Two authors independently reviewed 34 videos of ETS in 34 patients and 15 videos of NTEs in 15 patients. Initial screening and review was performed in an unblinded manner. Subsequently, the semiology was characterized independently and blindly by a co-author. Statistical analysis was conducted using Bonferroni correction and two-tailed Fischer exact test. Positive predictive value (PPV) was calculated for all signs. Cluster analysis of signs with a PPV >80% was performed to evaluate co-occurring semiological features in the two groups. ResultsCompared to patients with ETS, those with NTEs more frequently had predominant involvement of proximal upper extremities (UE) (67% vs. 21%), internal rotation of UE (67% vs. 3%), adduction of UE (80% vs. 6%) and bilateral elbow extension (80% vs. 6%). In contrast, those with ETS more frequently had abduction of UE (82% vs 0%), elevation of UE (91% vs. 33%), open eyelids (74% vs. 20%), and involvement of both proximal and distal UE (79% vs. 27%). In addition, seizures that remained symmetrical throughout were more likely to have a generalized onset than focal (38% vs. 6%), p = 0.032, PPV 86%. ConclusionsA careful analysis of semiology can often help differentiate between ETS and NTE in the ICU. The combination of eyelids open, upper extremity abduction, and elevation reached a PPV of 100% for ETS. The combination of bilateral arms extension, internal rotation, and adduction reached a PPV of 90.9% for NTE.

Neuropathy as the Initial Manifestation of Leprosy in an Older Patient (P3-10.004)

<h3>Objective:</h3> To consider Leprosy in the differential diagnosis of an older patient who presents with demyelinating polyneuropathy. <h3>Background:</h3> 70-year-old Bangladeshi Man with Diabetes Mellitus presents with two years of distal right arm numbness, right hand weakness, intermittent bilateral feet numbness, and prior blisters on the dorsolateral fingers. Neurologic exam revealed right arm distal&gt;proximal weakness, absent vibration in toes, decreased sensation to pinprick below the right elbow and bilateral ankles, and loss of proprioception of bilateral hallux. During initial skin evaluation no lesions were noted. <h3>Design/Methods:</h3> NA <h3>Results:</h3> Serology was unremarkable including ESR/CRP. EMG/NCS consistent with moderate sensorimotor demyelinating polyneuropathy and possible superimposed right lower trunk brachial plexopathy. MRI C-spine and brachial plexus were unrevealing. Due to EMG results and persistent symptoms Lewis Sumner Syndrome was considered. Ganglioside panel, celiac panel, and CSF studies were normal. On 3-year follow up, the patient developed worsening weakness and blisters of the left hand, and atrophy of the right hand. Dermatologic exam showed left hand hyperkeratotic plaques, right arm subcutaneous nodules, and hypopigmented patches on the trunk. Biopsy of a hypopigmented patch was negative for AFB. Repeat EMG/NCS showed decreased CMAP and SNAP amplitudes compared to the prior study in bilateral arms with continued ongoing denervation. Left medial antebrachial nerve biopsy confirmed Mycobacterium leprae. <h3>Conclusions:</h3> Leprosy is an infectious disease involving the skin, peripheral nerves, mucosal surface of the respiratory tract and eyes. Early diagnosis and treatment are essential to reduce the likelihood of disability as it is often irreversible and requires lifelong care. When leprosy occurs exclusively in neuropathic syndromes and at an older age, diagnosis can be difficult. Current classification systems rely heavily on skin manifestations, and diagnosis at the time of only peripheral nerve involvement can become challenging. As information accumulates on various neurological disorders in leprosy, it becomes increasingly clear that treatment paradigms should evolve. <b>Disclosure:</b> Dr. Sharma has nothing to disclose.

Paresthesia and Pain in Both Arms when Shampooing One’s Hair: Symptoms of Neurogenic Thoracic Outlet Syndrome

Neurogenic thoracic outlet syndrome (TOS) is a clinical diagnosis based on the reproduction of a patient’s symptoms with a provocation test (arm elevation) after excluding other conditions that might cause similar symptoms. Neurologic symptoms and signs can vary from mild paresthesia and numbness to intrinsic hand muscle atrophy. The main controversy in patients with neurogenic TOS involves neurologic-type complaints of paresthesia, numbness, and pain. However, there is no positive objective test to identify the cause. A 54-year-old female patient presented with numbness and radiating pain in her bilateral arms that occurred every time she bowed her head while shampooing. The patient had a history of two neck sprains due to slipping before the onset of symptoms. In addition to pain and numbness in both arms at arm elevation, pain in the suprascapular and occipital areas was also present. After excluding cervical nerve root lesions and other bone abnormalities, the patient's symptoms disappeared by brachial plexus decompression through a supraclavicular approach. It is difficult to diagnose neurogenic TOS with pain and paresthesia without muscle weakness in the upper extremities. If physicians do not consider the possibility of neurogenic TOS in patients with upper extremity paresthesia and pain, unnecessary multiple treatments may be performed, prolonging patients’ suffering. The exacerbation of pain and paresthesia in both arms and hands can occur immediately after the head is lowered during shampooing. This can be interpreted as a characteristic symptom of a constricted interscalene triangle and brachial plexus compression caused by hyperabduction of the arm.

How do alliances trade arms? Political alliance networks and global arms transfers.

The arms trade has come to the center stage of the international political economy. Yet only a few quantitative studies have been conducted on the political economy of the arms trade. This paper focuses on the security rents shared by trading partners in determining their arms trade relationship. We argue that the mechanism of reciprocity is better understood from the perspective of an international alliance network. Because the rents are likely to be transferred to other related members in a community, when a state is engaged in an arms deal with another state, it takes into account not only the direct dyadic relationship but also the alliance community to which the other state belongs. Based on this understanding, we employ social network analysis (SNA) to identify the effect of the international alliance community on the arms trade. Our findings suggest that if two states have a tie in a political alliance network, they are also likely to have a tie in the arms sale network. Moreover, we also find that the alliance network is a strong predictor of bilateral arms sales. Being in the same alliance community encourages two states to trade more arms with each other.
