Seronegative cat-scratch disease diagnosed by PCR detection of Bartonella henselae DNA in lymph node samples

AbstractCat scratch disease (CSD), the typical clinical manifestation of Bartonella infections usually follows a typical benign self-limited course. Nevertheless, a variety of unusual clinical manifestations and confusing imaging features can lead to misinterpretations and render the disease a diagnostic dispute. Routine laboratory tests exhibit varying reported sensitivity and are usually unhelpful in diagnosis, as serology fails in terms of specificity and/or sensitivity. Herein we report a case of seronegative Bartonella infection presenting as symptomatic suppurative lymphadenitis with abscess formation, which was surgically drained. Diagnosis was established by PCR analysis from lymph nodes samples obtained during the procedure. PCR detection of specific DNA fragments from lymph node biopsy provides a sensitive detection of disease. The technique should be considered for patients with suspected CSD and negative serology, since serological assays exhibit low sensitivity. In ambiguous cases, surgical exploration may provide tissue for diagnosis; it is well tolerated and affords improved recovery

Gabapentin for acute and chronic post-surgical pain

Pain after surgery remains a significant clinical problem as it impairs recovery adversely and may lead to the transition to chronic pain. Opioid medications are far from ideal agents in suppressing postoperative pain. Gabapentin -an anticonvulsant with antihyperalgesic properties- originally efficacious against neuropathic pain seems to be very promising for the management of pain after surgery as well. Gabapentin, by decreasing noxious stimulus-induced excitatory neurotransmitter release at the spinal cord, may attenuate central sensitization, and eventually decrease postoperative late pain. Furthermore, different sites of action may be pertinent to a synergistic effect with opioids. Both actions (antihyperalgesic effect and synergy with opioid analgesia) may manifest as analgesia and/or opioid-sparing effect after surgery. This has been confirmed by a variety of clinical studies, in a variety of settings. Most of these studies have shown that either single preoperative or repeated doses of gabapentin, continued for up to a few days after surgery, decrease acute postoperative pain and/or need for postoperative opioids. This has been shown for procedures such as abdominal and vaginal hysterectomy, breast surgery for cancer (mastectomy or lumpectomy), lumbar discectomy and spinal fusion, laparoscopic cholecystectomy and other, such as ENT surgery. Finally, a few studies indicate that perioperative gabapentin may as well decrease chronic pain several weeks after surgery

Two Cases of Primary Splenic Hydatid Cyst in Greece

Cystic disease of the spleen is an uncommon entity in general population. Most cases result from parasitic infection by Echinococcus granulosus, a form called splenic hydatid disease (SHD), with a reported frequency of 0.5-6.0% within abdominal hydatidosis. On the contrary, an isolated splenic involvement of hydatid disease is very uncommon even in endemic regions. Two cases of primary SHD managed with open and laparoscopic radical surgery in our department are reported herein. Primary SHD is a rare entity with non-specific symptoms underlying clinical suspicion by the physician for prompt diagnosis. Surgical treatment is the mainstay therapy, while laparoscopic approach when feasible is safe, offering the advantages of laparoscopic surgery

Association between smoking cessation and alterations in forced expiratory volume in one second (FEV1). A Follow-Up Study from a Greek Tobacco Cessation Clinic

Background: Cigarette smoking is the most important preventable cause of several diseases such as malignancies, pulmonary and cardiovascular diseases. Smoking cessation is now supported by both behavioral counseling and medical pharmacotherapy and is the only effective approach for slowing down an accelerated decline in forced expiratory volume in one second (FEV1). Our study aims to examine changes in forced expiratory volume in one second (FEV1) after smoking cessation for smokers attending our smoking cessation clinic their correlation to smokers’ demographic characteristics.Methods: 114 smokers (48 males and 66 females), with a mean age of 48.36±10.49 years, were enrolled. They were classified in 4 groups, according to their age; 60 years (Group D) and underwent Spirometry on the 1st day of visit, one month (2nd visit) and, 3 months later (3rd visit).Findings: Statistically significant increase in FEV1 values at the 2nd and 3rd visit compared to the 1st visit was observed in smokers who quit smoking in Group Α, B and C (p<0.05). In addition, a statistically significant decrease in FEV1 values at the 2nd and 3rd visit compared to the 1st visit was noticed in smokers who continued smoking in Group B, C and D (p<0.05).Conclusion: Smoking cessation achieved through smoking cessation support led to the improvement of FEV1 values within 3 months. The greatest benefit was observed in smokers under the age of 60

Postoperative abdominal free air: How much and when is enough? Report of two cases

Postoperative intraperitoneal or ectopic free air may occur after abdominal surgery, gynecologic surgery, laparoscopic surgery, or endoscopic procedures and, in rare cases, represent gastrointestinal perforation, requiring emergency laparotomy. Evaluating patients with postoperative signs of bowel perforation may be difficult, especially when day-case laparoscopic or endoscopic surgery is performed, with the patient readily discharged from hospital. Delayed diagnosis of gastrointestinal perforation due to underestimation of postoperative free air is associated with a high morbidity and mortality rate. We report two cases of patients presenting with postoperative free air along with the clinical presentation and management

Multimodal analgesia with gabapentin and local anesthetics prevents acute and chronic pain after breast surgery for cancer

We evaluated the effect of multimodal analgesia on acute and chronic pain after breast surgery for cancer. Fifty patients scheduled for breast cancer surgery were blindly randomized to receive gabapentin, eutectic mixture of local anesthetics cream, and ropivacaine in the wound or three placebos. Pain (visual analog scale) and analgesics were recorded in the postanesthesia care unit (PACU) 3, 6, and 9 h and 8 days after surgery. Three and 6 mo later, patients were assessed for chronic pain. The treatment group consumed less paracetamol in the PACU (469 versus 991 mg; P < 0.002) and less Lonalgal (1.0 versus 4.4 tablets; P = 0.003) than the controls, exhibited lower visual analog scale scores at rest in the PACU (P = 0.001) and on postoperative Days 1, 3, and 5 (P = 0.040, P = 0.015, and P = 0.045, respectively), and after movement in the PACU (P = 0.001) and on postoperative Days 2, 4, and 8 (P = 0.028, P = 0.007, and P = 0.032, respectively). Three and 6 mo after surgery, 18 of 22 (82%) and 12 of 21 (57%) of the controls reported chronic pain versus 10 of 22 (45%) and 6 of 20 (30%) in the treatment group (P = 0.028 and P = 0.424, respectively); 5 of 22 and 4 of 21 of the controls required analgesics versus 0 of 22 and 0 of 20 of those treated (P = 0.048 and P = 0.107, respectively). Multimodal analgesia reduced acute and chronic pain after breast surgery for cancer

Regional block and mexiletine: The effect on pain after cancer breast surgery

Background and Objectives: Breast surgery for cancer is associated with chronic pain and sensory abnormalities. The present study investigates the effect of regional block, oral mexiletine, and the combination of both, on acute and chronic pain associated with cancer breast surgery. Methods: One hundred patients scheduled for cancer breast surgery received either regional block with 18 mL of 1% ropivacaine intraoperatively and oral mexiletine for the first 6 postoperative days (R + M group), or regional block and placebo (R + PL), or normal saline instead of ropivacaine and mexiletine (PL + M), or normal saline and placebo (PL + PL). Postoperative analgesic requirements were recorded daily. Pain was assessed 0, 3, 6, 9, and 24 hours in the postanesthesia care unit (PACU) and on the second to sixth day postoperatively, at rest, and after movement using the visual analog scale (VAS). Three months after surgery, patients were interviewed for the presence and intensity of pain, abnormal sensations, and analgesic requirements. Results: Regional block reduced the number of intramuscular (IM) injections required the first 24 hours (P = .05), the R + PL group requiring less injections versus the PL + M group (P = .037). Lonarid tablet (paracetamol and codeine) consumption from the second to the fifth postoperative day differed among the 4 groups (P = .0304), the R + M group requiring fewer tablets than the PL + PL group (P = .009). Three hours postoperatively, the R + PL group had less pain at rest when compared with all other groups (P < .05 for all comparisons). On the second postoperative day, VAS at rest and after movement was less in the R + M versus the R + PL group (P < .01 and P < .05, respectively). Three months after surgery, the 4 groups were similar with regard to incidence or intensity of pain or analgesic requirements. The R + PL group had a lower incidence (77%) of reduced or absent sensation (P = .016). Conclusions: Regional block reduced the analgesic requirements in the early postoperative period, while mexiletine combined with regional block reduced the total analgesic requirements during the next 5 postoperative days. Although chronic pain was not affected by these treatments late-abnormal sensation may be diminished by combination of these treatments. Reg Anesth Pain Med 2001;26:223-228

EMLA reduces acute and chronic pain after breast surgery for cancer

Background and Objectives: A significant percentage of women undergoing breast surgery for cancer may develop neuropathic pain in the chest, and/or ipsilateral axilla and/or upper medial arm, with impairment in performing daily occupational activities. We designed this study to determine if the perioperative application of EMLA (eutectic mixture of local anesthetics; AstraZeneca) cream in the breast and axilla area reduces analgesic requirements, as well as the acute and chronic pain after breast surgery. Methods: Forty-six female patients scheduled for breast surgery received randomly 5 g of EMLA or placebo on the sternal area 5 minutes before surgery, and 15 g on the supraclavicular area and axilla at the end of the operation. Treatment with EMLA cream (20 g) or placebo was also applied daily on the 4 days after surgery. In the postanesthesia care unit (PACU), 3, 6, 9, and 24 hours after surgery, and on the second to sixth day postoperatively, pain was assessed by visual analogue scale (VAS) at rest and after movement, and postoperative analgesic requirements were recorded. Three months later, patients were asked if they had pain in the chest wall, axilla and/or medial upper arm, decreased sensation, if they required analgesics at home, and for the intensity of pain. Results: Acute pain at rest and with movement did not differ between the EMLA and control groups, and the analgesics consumed during the first 24 hours were the same for the EMLA and control groups. However, time to the first analgesia requirement was longer ( P = .04), and codeine and paracetamol consumption during the second to fifth days was less ( P = .001, and P = .004, respectively) in the EMLA versus the control group. Three months postoperatively, pain in the chest wall, axilla, and the total incidence and the intensity of chronic pain were significantly less in the EMLA versus the control group ( P = .004, P = .025, P = .002 and P = .003, respectively). The use of analgesics at home and abnormal sensations did not differ between the 2 groups. Conclusions: The application of EMLA to patients undergoing breast surgery for cancer reduced the postoperative analgesic requirements and the incidence and intensity of chronic pain.
