Case report: a patient with Hodgkin's disease after treatment for testicular cancer.

A young patient developed Hodgkin's disease 11 years after surgical, chemotherapeutic and radiation treatment for stage IIIA embryonal carcinoma of the testis. The importance is stressed of establishing a tissue diagnosis when there is an unexpected course of the disease.     

Predicted versus observed FEV1 in the immediate postoperative period after pulmonary lobectomy.

OBJECTIVE: Scanty information can be found regarding ppoFEV1% correlation with true FEV1% in the immediate days after surgery, when most cardio-respiratory complications are developed. This prospective multicentric investigation aims to describe the evolution of FEV1 in a series of uneventful lobectomy cases before hospital discharge, and to identify factors associated with the variation of postoperative residual FEV1, with the ratio between the actual and the predicted postoperative FEV1 measured during the first 6 postoperative days. METHODS: One hundred and sixty-one patients submitted to lobectomy were prospectively enrolled in the study. Patients with chest wall resections and postoperative complications were excluded. Data from a total of 125 patients were thus used for the analysis. The following clinical variables were recorded: age, preoperative FEV1, ppoFEV1, presence of chronic obstructive pulmonary disease (COPD), surgical approach (VATS or muscle-sparing thoracotomy), side (right or left) and site (upper or lower) of resection, type of analgesia (epidural or intravenous), and daily visual analogue pain score (VAS). FEV1 was measured in every patient at hospital admission and daily until discharge or up to postoperative day 6. Random effects time-series cross-sectional regression analyses were performed to identify factors associated with variation of postoperative residual function (100-(preoperative FEV1-postoperative FEV1/preoperative FEV1 x 100)), and of FEV1 ratio ((actual postoperative FEV1 x 100)/ppoFEV1). For these analyses, the dependent variables (postoperative residual function and FEV1 ratio) and the pain score were analysed as panel longitudinal data. The regression analyses were subsequently validated by bootstrap procedure. RESULTS: FEV1% was lower at first postoperative day and increased gradually up to day 6 but mean values never reached ppoFEV1%. Pain scores decreased from day 1 to day 6. Preoperative FEV1 (p<0.0001) and postoperative pain score (p<0.0001) resulted independently and reliably inversely associated with postoperative residual FEV1 (model R2, 0.16). Preoperative FEV1 (p=0.001), postoperative pain score (p<0.0001), and epidural analgesia (p=0.04) resulted independently and reliably associated with postoperative FEV1 ratio (model R2, 0.13). CONCLUSION: Current methods of prediction of postoperative FEV1 greatly underestimated the real functional loss in the immediate postoperative period. Therefore, for the purpose of a more accurate risk stratification we need to correct the traditional prediction of postoperative FEV1.     

Spinal lipomas in childhood]

Spinal lipomas account for 5% of the tumors of the spinal cord, frequently present already at birth. Most commonly they are associated with forms of dysraphism, but lipomas without bony involvement are considered dysembriogenetic lesions too. Children with lipoma frequently have intact neurological functions, but may become symptomatic later on. Diagnosis is possible also in neurologically intact patients because of skin lesions or subcutaneous masses. Many surgeons suggest early surgery to prevent injury to neural structures from traction due to cord tethering; others prefer to wait for the rise of any symptom before considering surgery. However, neurological recovery after surgery is rarely observed, and, when present, is always partial; the primary goal of surgery is to stop the clinical progression through the detethering of the cord.     

An algorithm for the treatment of pain in advanced cancer

An algorithm is presented that has been developed over the past three years to provide pain relief in advanced cancer. The hospital records of 92 patients were reviewed to evaluate the validity of the algorithm. The algorithm is as follows: the 24 hour oral consumption of opioids was converted to sustained release morphine. If ineffective usually over 360 mg daily the total 24 hour oral dose was divided by 6 to convert to I.V. If this was ineffective, usually over 10 mg/hr of morphine, the intravenous dose was divided by 10 and infused epidurally. Local anesthetic was added for plexus involvement. After four days, the patient was weaned from local anesthetic solution. If sharp pain or pain to movement persisted, 6% phenol in 1 to 2 ml aliquots was injected every 8-12 hours to a total of 5-8 ml. While the conversion from intravenous to epidural morphine was 10:1 that from epidural to intravenous was only 1:3. Intravenous dose converts directly to the subcutaneous. The conversion from intravenous to oral is 1:3. There view showed that the dosages at which the conversions were made varied considerably. The reasons for the wide variation are presented. In summary the algorithm is a good practical guide for treatment of cancer pain.     

Effect of ritanserin, specific 5HT-2 antagonist, on PRL secretion in normal subjects and in different hyperprolactinaemic conditions

The availability of a new specific anti 5HT-2 compound, ritanserin (RTS), led us to further investigate the role of serotonin in controlling PRL secretion. The drug was administered to normoprolactinaemic subjects and to patients with differing hyperprolactinaemic conditions. While RTS failed to modify PRL levels in normoprolactinaemic subjects and in patients with PRL-secreting pituitary adenomas, a marked decrease in the hormone was obtained in patients with functional and puerperal hyperprolactinaemia. The lack of effect of RTS in PRL-secreting pituitary adenomas suggests that the reported suppression of PRL by other antiserotoninergic drugs, such as metergoline, is probably due to their concomitant dopaminergic activity.     

Modern Morbidity following Pulmonary Resection for Postprimary Tuberculosis

n = 8), multidrug resistance or noncompliance to the medical treatment ( n = 11), parenchymal sequelae ( n = 3), suspected cancer ( n = 5), and for the correction of postpneumonectomy bronchopleural fistula and empyema ( n = 1). On admission, eight patients presented with sputum positivity (28.6%). Similar to previous series, tubercular predilection for upper lobes was confirmed (21/28, 75%); accordingly, upper lobectomy through an extrapleural approach was the most common procedure (16/28, 57.1%). Atypical segmental resections or segmentectomies were performed in seven patients (25%), whereas a bilobectomy was necessary in another three patients (10.7%) and a completion pneumonectomy in one (3.6%). Additional procedures were an open-window thoracostomy with transpericardial closure of the main bronchus and a tailored thoracoplasty. No operative mortality was reported. Healing was achieved in 26 patients (93%). Bleeding, either from the chest wall or hilar dissection, was the only reported intraoperative complication. Median blood loss, inclusive of early postoperative collections from chest tubes, reached 1330 ml (range 100–3700 ml). Major postoperative complications included recurrent disease (2/28, 7%) in sputum-positive patients and segmental pulmonary embolism (3.5%). Causes of minor morbidity were air leaks resulting in residual space undergoing spontaneous resolution (18%), wound breakdown (14%), and, fever (11%). This limited series confirms the therapeutic value of the surgical treatment of postprimary tuberculosis, provided that correct indications, adequate pre- and postoperative medical coverage, and meticulous technique are applied.     

Prevalence and localization of nodal metastases in squamous cell carcinoma of the oral cavity: role and extension of neck dissection

Lymph node (LN) metastases represent the most important negative prognostic factor in squamous cell carcinoma (SCC) of the oral cavity, even though controversies still exist regarding their management. The aim of this study was to retrospectively analyze our experience in surgical management of SCC of the oral cavity with particular focus on the prevalence and localization of lymph nodal metastases and recurrences. The clinical records of 89 consecutive patients treated from 1983 to 2002 by concomitant surgery on both the T and N sites, excluding those undergoing salvage surgery, were reviewed. A total of 119 neck dissections (ND) were performed. Survival outcomes were calculated by the Kaplan–Meier method, while univariate comparisons by the log-rank and non-parametric tests were performed between different groups of patients. Five-year overall and determinate survivals were 50 and 57%, respectively. LN metastases were observed in 52% (56% of these showing extracapsular spread) and their presence strongly correlated with determinate survival (p < 0.0001). The prevalence of clinical and occult nodal disease was not related to the pT status. Neck levels II (59%) and I (56%) were most frequently involved. Metastases to level IV accounted for 15% of positive LN, even though 28% of them turned out to be skip metastases. Five neck recurrences were observed, only one of which was salvaged by surgery. The high prevalence of clinical and occult LN metastases in this setting suggests that ND should be performed on a nearly routine basis, even for lesions with a low-T category and a cN0 neck. Moreover, ND should always encompass level IV due to the possibility of skip metastases, particularly in tumors involving the oral tongue. In patients with a cN+ neck, levels from I to V should be addressed, particularly in the presence of metastases at levels III and IV.     

Carbon dioxide laser salvage surgery after radiotherapy failure in T1 and T2 glottic carcinoma.

OBJECTIVES: Recurrent glottic carcinoma after radiotherapy (RT) may be managed by open neck or endoscopic surgery. The impact of endoscopic treatment with CO(2) laser for recurrent glottic carcinoma after RT is reported. METHODS: We present the oncologic and vocal outcomes of a retrospective study based on a series of 16 patients with rT1 and rT2 glottic carcinoma who were endoscopically managed between February 1995 and December 1999 after RT failure. All patients were males with a mean age of 68.7 years (range, 50 to 87 years). Before RT, the lesions had been staged as T1 N0 in 11 patients and T2 N0 in 5, and after RT as rT1 N0 in 12 and rT2 N0 in 4. According to the European Laryngological Society classification, a total of 9 transmuscular, 3 total, and 4 extended cordectomies were performed. Mean follow-up was 45 months (range, 9 to 79 months). RESULTS: Endoscopic salvage surgery was successful in 14 patients. One of them developed a second recurrence and was definitively cured with an additional endoscopic procedure. Two of the 16 patients had recurrent disease after salvage laser surgery and died due to progression of disease. Ultimate local control with laser alone at 3 years was 87.1%, according to the Kaplan-Meier method. Laryngeal preservation was obtained in all survivors after endoscopic rescue surgery. Voice analysis showed a clear correlation between the amount of vocal cord tissue resected and decrease of the vocal outcome. CONCLUSIONS: The present series indicates that selected recurrences after primary RT for T1 and T2 glottic carcinoma are eligible for endoscopic salvage surgery with oncologic results comparable to those with open neck procedures but with a lower complication rate and a favorable functional outcome.     

Kidney transplant monitoring by anti donor specific antibodies

Donor-specific anti-HLA antibodies were studied by cytotoxicity crossmatching (CTXM) and flow cytometry crossmatching (FCXM) in 117 kidney transplant candidates; the same study was carried out in 33 cadaver-donor kidney recipients, during the first 3 post-transplant months, for which donor cells were available. Pre-transport evaluation showed that 82.9 % of subjects were CTXM negative/FCXM negative, 6.8 % of patients were positive in both tests, and 10.3 % were CTXM negative/FCCM positive. Post-transplant monitoring for donor-specific antibodies (Abs-DS) showed that nine recipients (27.3 %) were FCXM positive; six of them were IgG + and three IgM +. In comparing these results with the clinical course, a significant association between FCXM IgG + and rejection episodes was observed (P < 0.01).
