Bilateral phrenic neuropathy responsive to intravenous immunoglobulin treatment

The aetiology of phrenic neuropathy is often unknown, but immune mechanisms may play a role. In a typical case of bilateral phrenic neuropathy with paradoxical breathing (video), an inflammatory pathogenesis was suggested by prolonged distal latency of phrenic nerve compound muscle action potentials in nerve conduction studies and a clear-cut albumin-cytologic dissociation. This encouraged us to treat the patient with a standard dose of intravenous immunoglobulin. After obtaining a strong improvement at spirometry, we repeated the second cycle of intravenous immunoglobulin and observed normalization of symptoms within few weeks and no relapse after 3 years. This case suggests that lumbar puncture should be performed in the acute phase of phrenic neuropathies to detect potential responders to immunomodulatory treatment.

Poland Syndrome: Use of Vertical Expandable Prosthetic Titanium Rib System before Walking Age—A Case Report

Aim To present a new therapy for Poland syndrome (PS) using a novel surgical approach: the vertical expandable prosthetic titanium rib (VEPTR) system. Methods The VEPTR system rib-to-rib variant was used to enhance the chest wall and vertebral column support in a young patient before walking age. Case Report We present a 12-month-old infant diagnosed with left-sided PS at the age of 6 months associated with missing ribs, scoliosis, and absence of the left pectoral muscles. Because of four missing ribs, paradoxical breathing was present. In addition, the left scapula was protruding into the chest due to the missing rib support. Scoliosis was caused by a left-sided nonsegmented bar of the thoracic spine. Results We decided to use the VEPTR system before the patient reached walking age to prevent progression of column deformation and future pulmonary problems. To improve the spinal deformity, to stabilize the thorax, and to improve thoracic function, we performed the operation at 1 year of age. At 10-month follow-up, the patient was reevaluated. The construction was still stable and scoliosis had not deteriorated. Conclusion The VEPTR system is a choice of treatment in young patients with PS to prevent late complications after a child reaches walking age.

Congenital Paraesophageal Hernia in a Cat

ABSTRACT A 3 mo old male domestic shorthair weighing 2 kg was presented for acute onset of anorexia, lethargy, paradoxical breathing, and a palpable mass effect in the cranial abdomen. Initial diagnostics and imaging suggested a pleuroperitoneal or hiatal hernia. Emergency abdominal exploration was performed, and a complex type II paraesophageal hiatal hernia was identified. The entire stomach, greater and lesser omenta, spleen, left limb of the pancreas, and the proximal segment of the descending duodenum were herniated through a discrete defect in the phrenicoesophageal ligament. After reduction of the herniated organs back into the abdomen, a phrenicoplasty, esophagopexy, and left-sided fundic gastropexy were performed. The cat recovered uneventfully from the procedure and was free of any signs of disease for at least 30 mo postoperatively. This is the first detailed report of the findings and successful surgical treatment of a complex congenital, type II paraesophageal hiatal hernia with complete herniation of the stomach, omenta, and spleen in a cat.
