Rationale: Entrapment neuropathies are peripheral nerve disorders at specific anatomical locations. They may be caused by trauma in a manner of sprains or bone fracture, but it is often caused by repetitive insults or compression of nerves as they travel through a narrow anatomic space. Pregnancy and pre-existing comorbidities such as diabetes, obesity, cancer, or autoimmune diseases may also cause nerve entrapment.

Objective: To highlight the case of a 52-yearold female developing right foot dysesthesia and weakness after continuous restraint strapping from her previous hospitalization.

Case: Here we have the case of a 52-year-old Filipino female consulted because of right foot dysesthesia, allodynia, and mild weakness. She had a history of bipolar disorder and recent onset of acute psychosis and overdosing with her irregularly taken maintenance olanzapine tablets. She was put on restraint strapping of the right lower limb in her one-week hospital stay. This resulted in developing restraint marks on her right ankle accompanied by difficulty walking on heels and toes, spontaneous dysesthesia, and touch allodynia of her entire right foot. An electrodiagnosis yielded right lower limb focal neuropathies involving the right fibular nerve, right tibial nerve, right superficial fibular, and right sural nerves. The prescribed amitriptyline and gabapentin for 6 months led to gradual improvement of neuropathic pain.

Discussion and Summary: Our case exemplifies focal limb neuropathies from entrapment due to restraint strapping. Electrodiagnostic confirmation of neuropathies of the same limb sensory and motor nerves was mandated to corroborate clinical neuropathic pain and after ruling out other causes of entrapment neuropathies. Prolonged use of neuropathic pain medications were needed to attain relief in this present case. Restrictive strapping is an iatrogenic cause of entrapment neuropathy that is preventable, had there been proper medical attention applied.

The most prevalent microvascular complication of diabetes mellitus is neuropathy, which encompasses distal symmetric polyneuropathy, mononeuropathy, radiculoplexopathy, and autonomic neuropathy. Intensive glucose control prevents and effectively halts the progression of diabetic neuropathy in patients with type 1 diabetes mellitus. However, the effect of strict glucose control itself is at modest in those with type 2 diabetes. Although we have better understanding of the mechanism of diabetic neuropathy, many pharmacologic trials for the targeting underlying nerve damage have reported unsuccessful results. In this review, the effects and limitations of the current therapeutic options will be discussed.

Meralgia paresthetica (MP) is a sensory mononeuropathy, caused by compression of the lateral femoral cutaneous nerve (LFCN) of thigh. Patients refractory to conservative management are treated with various interventional procedures. We report the first use of extended duration (8 minutes) pulsed radiofrequency of the LFCN in a case series of five patients with refractory MP. Four patients had follow up for 1–2 years, and one had 6 months follow up. All patients reported remarkable and long lasting symptom relief and an increase in daily life activities. Three patients came off medications and two patients required minimal doses of neuropathic medications. No complications were observed.

A 41-year-old man suffering from eosinophilic granulomatosis with polyangiitis (EPGA), diagnosed at another clinic on the basis of American College of Rheumatology Criteria, with a history of bronchial asthma, eosinophilia, mononeuritis multiplex, and non-fixed pulmonary infiltrates, was admitted to our department for further treatment. The patient complained of chest pain that started recently. An echocardiogram identified myocardial thickening and decreased wall motion, based on which the patient was diagnosed as having EPGA with myocarditis. The patient was successfully treated using glucocorticoids, such as methyl prednisolone (PSL) and PSL in combination with cyclophosphamide (CPM). However, CPM administration was discontinued afterwards because of the risk of bone marrow toxicity, the increased eosinophilic count (EOC) that we considered as an index of disease activity. Subsequently, the patient received additional clarithromycin (CAM) and tacrolimus (TAC) treatment considering their immunomodulatory effects. As a result, the EOC decreased and the PSL dosage could be reduced. This case shows that additional CAM and TAC treatment may be beneficial in some cases of EPGA.

Meralgia paresthetica (MP) is a painful mononeuropathy of the lateral femoral cutaneouse nerve (LFCN) characterized by localized symptoms of numbness, tingling, pain and paresthesia along the anterolateral thigh area. L4 and L5 radiculopathy is set of symptoms that include sharp, burning or shooting pain, which is usually localized to anterolateral leg area and along the dermatomal distribution. When symptoms of MP and lumbar disc disease occur together it is not easy to diagnose MP. We report a case of synchronous post-traumatic MP and radiculopathy due to intervertebral disc herniation at L3–4 and 4–5. A 59-year-old male patient was admitted to the emergency room with symptoms of low back pain with left severe L4, L5 radiculopathy. This patient also complained of numbness and paresthesia in the left anterolateral thigh. After detailed history taking and lateral femoral cutaneouse nerve block, he was diagnosed with MP.

Peroneal neuropathy is a common mononeuropathy of the lower limb. Some studies have reported cases of peroneal neuropathy after vascular surgery or intervention. However, no cases of peroneal neuropathy with occlusion of a single peripheral artery have been previously reported. A 73-year-old man was referred with a 3-week history of left-sided foot drop. He had a history of valvular heart disease and arrhythmia, and had previously been treated with percutaneous coronary intervention. Computed tomography angiogram of the lower extremity showed proximal occlusion of the left anterior tibial artery. An electrodiagnostic study confirmed left common peroneal neuropathy. After diagnosis, anticoagulation therapy was started and he received physical therapy.

Meralgia paresthetica (MP) is a sensory mononeuropathy of the lateral femoral cutaneous nerve (LFCN). MP has rarely been reported after a femoral intervention approach. We report a case of bilateral meralgia paresthetica following bilateral femoral cannulation. A 64-year-old male received cardiac catheterization and treatment via a bilateral femoral vein. After cardiac catheterization, the patient presented with paresthesia in the anterolateral aspect of the bilateral thigh. After performing nerve conduction studies and electromyography, he was diagnosed as MP. Although a bilateral LFCN lesion following a femoral approach is very rare, MP might require caution regarding potential variations in LFCN when performing the femoral approach.

Cryoglobulinemia is a rare medical condition defined by presence of cryoglobulins in serum and it may cause hyperviscosity syndrome or systemic vasculitis in variable organs including the skin, joints, liver, kidneys, lungs and nervous system. A vasculitic polyneuropathy or mononeuritis multiplex commonly occurs. However, central nervous system complications of cryoglobulinemia including stroke, encephalopathy and seizures are rarely reported. We represent a case of essential cryoglobulinemic vasculitis manifested as a sensorimotor polyneuropathy combined with an acute ischemic stroke attack.

Neurolymphomatosis (NL) defined as infiltration of the central nervous system or the peripheral nervous system (PNS) by malignant lymphoma cells is a rare clinical entity. However, the increasing use of fluorodeoxyglucose positron-emission tomography (FDG-PET) and magnetic resonance imaging in evaluating PNS disorders is resulting in; this condition being recognized more frequently. Here; we report five NL patients and review the current literature. We report five patients with non-Hodgkin's lymphoma (NHL) and NL, all of whom were men aged 47-69 years. The clinical presentation varied from symmetrical peripheral neuropathy to mononeuropathy. Peripheral neuropathy was the presenting manifestation of a systemic lymphoma in two patients (40%). Neuroimaging as well as whole-body FDG-PET helped in determining the correct diagnosis in all of the patients. NL is an unusual presentation of NHL resulting from infiltration of the PNS by malignant lymphomatous cells. While evaluating peripheral neuropathy, a high degree of suspicion of NL is required since the presenting symptoms vary, conventional radiology has only modest sensitivity, and a pathological diagnosis is often difficult. FDG-PET helps in the early diagnosis and treatment of this condition.
