Lucio phenomenon mimicking antiphospholipid syndrome: The occurrence of antiphospholipid antibodies in a leprosy patient

Lucio phenomenon is an atypical reaction of leprosy, characterized by vasculitic lesions that can mimic antiphospholipid syndrome (APS) clinically. Distinguishing the two can be difficult as antiphospholipid autoantibodies may be present in patients with leprosy. We report on a 32‐year‐old female patient presenting with a sudden onset of fever, hemorrhagic bullae, and skin necrosis on her lower legs. She was treated for APS due to the presence of antiphospholipid antibodies but had an inadequate response. A skin biopsy revealed thrombotic vasculopathy and necrotizing vasculitis associated with aggregation of foam cells in the perivascular area and subcutis, with acid‐fast bacilli in the histiocytes and blood vessel walls. Direct immunofluorescence showed IgM, C3, and fibrinogen deposition in the superficial and deep dermal blood vessels. The pathology confirmed the diagnosis of Lucio phenomenon, and appropriate therapy was given. It is essential to evaluate the patient comprehensively, including clinical, serological, and pathological aspects, to obtain the correct diagnosis.     

Treatment of the infected pseudoarthrosis of the tibia by the Harmon method]

The principles of treatment of tibial pseudoarthroses complicated by skin and soft tissue loss with the use of cancellous bone grafts from posterolateral approach to the tibia by Harmon method were discussed. The detailed surgical technique was presented. Management of 3 patients that resulted in bone union was described.     

Porphyria cutanea tarda associated with autoimmune hypothyroidism, vitiligo and alopecia universalis.

The aetiology of porphyria cutanea tarda (PCT) has not been elucidated, but the possibility of an autoimmune mechanism has been proposed. We report a case of an unknown clinical combination of PCT with autoimmune hypothyroidism, alopecia universalis and vitiligo with thyroid and parietal cell circulating antibodies. This is highly suggestive of underlying autoimmune damage in this patient.     

Müllerian adenosarcoma of the uterus

Histologic structure of Mueller's adenosarcoma has been studied in 5 patients subjected to uterine and its appendages extirpation. Microspectrophotometric assessment of the course of nuclear DNA accumulation, measurement of X-chromatin in two morphologic components of the tumor (epithelial and stromal) confirmed malignant morphological nature of the latter and benign one of the former. Basing on their experience with the 5 patients three of which died in the course of 5 years of relevant metastases, the authors believe the prognosis for uterine adenosarcoma to be poor.     

Analyses of serum vitamin D-binding protein, ceruloplasmin and copper levels in preterm infants.

The cord blood specimens of 12 preterm and 20 term babies were investigated. We determined serum calcium (Ca), phosphorus (P), magnesium (Mg), vitamin-D binding protein (DBP), ceruloplasmin (Cp) and copper (Cu) levels in two groups. We found that Ca, P, and MG levels of cord sera did not differ between the groups (p > 0.05), but DBP, Cp and Cu values showed a significant decrease in the preterm group (p < 0.05). The Cu and Cp values of the preterm infants correlated with those of the term infants.     

Effects of nocturnal desaturation on pulmonary hemodynamics in patients with overlap syndrome (chronic obstructive pulmonary disease and obstructive sleep apnea)

We studied pulmonary haemodynamics and nocturnal desaturation in 17 patients with an overlap syndrome (OS), all males, mean age 51.4 +/- 8.3 years, mean BMI 37 +/- 4.2 kg/m2. Diagnosis of COPD was based on pts history, clinical examination, lung function tests and chest radiography. Spirometry showed: FVC 2.7 +/- 0.7 L (59 +/- 16% N), FEV1 1.5 +/- 0.7 L (43 +/- 16% N), FEV1% FVC 54 +/- 13%, Raw 0.58 +/- 0.4 kP.s/L, RV 3.3 +/- 1.2 L (144 +/- 51% N), TLC 6.6 +/- 1.3 L (100 +/- 14% N) and RV% TLC (49.5 +/- 12.1%. Arterial blood gas values were: PaO2 56.9 +/- 9.5 mmHg, PaCO2 46.9 +/- 9.8 mmHg, pH 7.37 +/- 0.05. Mean apnoea/hypopnoea index (AHI) was 63.9 +/- 18.9. Pulmonary haemodynamics at rest (Swan Ganz thermodilution catheter) were: mean pulmonary artery pressure (PAP-SP) 24.2 +/- 7.4 mmHg, mean pulmonary wedge pressure (PW-SP) was 9.1 +/- 7.3 mmHg, cardiac output (CO-SP) was 5.6 +/- 2.3 L/min. and pulmonary vascular resistance (PVR) was 229 +/- 97 dyn.sec.cm-5. During exercise (40 Watts, 7 mins, in 8 pts) PAP rose from 19 +/- 6 mmHg to 41.2 +/- 15.1 mmHg, PW rose from 7.4 +/- 7.2 mmHg to 11 +/- 10.2 mmHg, CO rose from 5.8 +/- 2.7 L/min to 12.7 +/- 2.4 L/min. Overnight pulse oximetry showed: mean oxygen saturation (SaO2 mean) 80.2 +/- 8.5%, minimal saturation (SaO2 min) was 50.7 +/- 19.7%. Time spent in desaturation SaO2 < 90% (T 90) was 76.9 +/- 25.7%. We conclude that pts with OS have resting pulmonary hypertension and elevated PVR. During low grade exercise the rise in PAP was highly abnormal. Statistical analysis showed no correlations between nocturnal SaO2 and diurnal pulmonary haemodynamics data.     

Stability-indicating determination of adrenaline in injections containing procaine

Adrenaline was determined in injections containing procaine in a 1000-fold excess by reversed-phase high-performance liquid chromatography using UV detection at 205 nm and aqueous sulphuric acid (100 μmol/l) as eluent. The relative standard deviation was 2.1%, and the method was selective in the presence of adrenaline degradation products. Changes of the capacity factor with pH and ionic strength of the eluent were studied, and a simple model is suggested to explain the retention data.
