Randomized trial of aromatherapy. Successful treatment for alopecia areata

We studied 2 groups of patients with (n = 14) and without (n = 42) minor coronary dissections following cutting balloon angioplasty. Patients with a minor dissection had a longer length of lesion, higher percentage of stenosis, and greater acute gain after angioplasty; at 6-month follow-up both groups had a similar net gain and restenosis rate, suggesting that minor dissection after cutting balloon angioplasty has no influence on restenosis.     

Successful treatment of experimental murine Trypanosoma brucei infection with topical melarsoprol gel

Melarsoprol gel applied topically (0.1 mL for at least 2 d) can cure late-stage Trypanosoma brucei brucei and T. b. rhodesiense infections in mice. The best regimen was 3 applications at approximately 0, 6, and 24 h. The melarsoprol gel retained its activity at room temperature for at least 63 d. There was only minimal skin irritation and no sign of toxicity.     

Epstein-Barr virus-related primary cutaneous amyloidosis. Successful treatment with acyclovir and interferon-alpha

Cutaneous lesions related to chronic active Epstein-Barr virus (EBV) infection have been rarely documented in immunocompetent patients. A 30-year-old woman, fulfilling the diagnostic criteria for the chronic fatigue syndrome, had a 10-year history of pruritic brownish macules and papules on her chest and back. Her EBV serology was abnormal; the EBV genome was present in the epidermis of lesions, in oral secretions, and in peripheral mononuclear cells (PMC). Her blood lymphocytes spontaneously outgrew in culture. Histology revealed deposits of amyloid in the papillary dermis. Treatment with acyclovir and interferon-alpha rapidly improved her condition, stopped the lymphocyte outgrowth in culture, and reduced the EBV DNA content in oral secretions and in PMC. These data support an endogenous reactivation of EBV infection and suggest a causal relationship with primary amyloidosis.     

Facial alopecia in the rabbit associated with Cheyletiella parasitivorax

A facial dermatitis characterized by alopecia over the frontal area with varying degrees of erythema and scale formation was observed in 46 newly arrived New Zealand White rabbits within a 5-month period. The clinical history, nature of the lesion, and laboratory findings indicated that the mite Cheyletiella parasitivorax was the most likely cause of the dermatitis.     

Successful treatment of cutaneous Kaposi's sarcoma by the 585-nm pulsed dye laser

The clinical appearance of Kaposi's sarcoma (KS) can cause significant disfigurement and lead to functional impairment, particularly if the lesions ulcerate and become secondarily infected. We describe a patient with a KS plaque on the face that was successfully treated with 585-nm pulsed dye laser (PDL) therapy. No recurrence of the tumor was noted 12 months after the final laser treatment.     

Successful treatment of a persistent cutaneous fistula to the seminal tract: imaging with three-dimensional computed tomography

The best position for Centers for Disease Control (Atlanta, GA) light traps, in relation to human-occupied bed nets for trapping of host-seeking Anopheles gambiae Giles and Culex quinquefasciatus Say mosquitoes, was determined in Tanzania. Significantly higher catches were recorded for both species when the trap was positioned at the foot end of the bed, near the top of the net. Parity rates were significantly higher near the top of the net than at the level of the host. Since trap position affects the catch size and the proportion of infectious mosquitoes therein, standardized use of this sampling technique for estimating entomologic inoculation rates (i.e., the number of potentially infectious bites received over a certain period of time) is recommended.     

Angiosarcoma (angioendothelioma) of the scalp. An unusual case of scarring alopecia

Angiosarcoma with initial involvement of the scalp is a rare, malignant neoplasm. We present the case of a 77-year-old woman in whom extensive scarring alopecia developed that was proved histologically to be due to angiosarcoma. She had a good initial response to treatment with electron-beam therapy, but after seven months, extensive nodules and indurated areas on the face beyond the borders of the radiation field developed. Subsequently, massive cervical adenopathy and metastases to the lungs, liver, and spleen developed. Angiosarcoma must be differentiated from other malignant blood vessel tumors and should be considered in the differential diagnosis of scarring alopecia of the scalp in elderly patients.     

Successful treatment with CPT-11 and adriamycin for hemophagocytic syndrome associated with intravascular lymphomatosis

A 75-year-old man was admitted because of non-Hodgkin's lymphoma (histology undetermined) of the rib. A complete remission was achieved after CHOP therapy and irradiation. One year later, high fever, thrombocytopenia and liver dysfunction developed. Bone marrow aspirate revealed a hypoplastic marrow with hemophagocytic histiocytes, and a diagnosis of hemophagocytic syndrome (HPS) was made. Although no lymphomatous lesions were detected, HPS due to relapsed lymphoma was strongly suspected. The patient received MEVP therapy including etoposide and prednisolone, but without any improvement. Soon after the initiation of CPT-11 and adriamycin (ADM) therapy, all symptoms of HPS disappeared. This combination chemotherapy was repeated over a three-week span, and the patient remained in partial remission for the next 10 months. In November 1997, a tumor developed in the paranasal sinus, and the patient died three months later. The autopsy disclosed many B lymphoma cells filling the small vessels of almost all organs, and a final diagnosis of intravascular lymphomatosis (IVL) was made. These findings indicate that combination CPT-11 and ADM therapy is effective for cases of IVL accompanied by HPS that are refractory to conventional chemotherapies.     

Successful conservative treatment for esophageal perforation by a fish bone associated with mediastinitis

A 74 year-old man presenting with esophageal perforation associated with mediastinitis due to the swallowing of a fish bone is reported herein. Conservative treatment, including starvation therapy and the injection of antibiotic drugs, proved to be successful for this patient. Although the optimal treatment for esophageal perforation remains controversial, it is important to choose the appropriate strategies when treating cases of esophageal perforation with mediastinitis.     

Lacrimal canalicular obstruction associated with topical ocular medication

An uncultured bacterium of the Verrucomicrobiales cluster was identified by its 16S rDNA sequence as a major bacterium in Dutch Drentse A grassland soils. Potential metabolic activity of the according organism was estimated by applying direct ribosome isolation from soil and partial amplification of the 16S rRNA via RT-PCR using bacteria-specific primers. Temperature gradient gel electrophoresis separated the amplicons sequence specifically into reproducible fingerprints. One of the fingerprint bands matched with the signal of clone DA101. Southern blot hybridization with a DA101-specific V6 probe confirmed sequence identity. It is the first time that an organism of the Verrucomicrobiales cluster has been indicated as a potential major metabolizer in environmental microbial communities.     

Successful treatment of cyclic neutropenia associated with hyperimmunoglobulin M syndrome using recombinant granulocyte-colony stimulating factor

Hyper-IgM syndrome associating with severe neutropenie presenting in irregularis cycles was diagnosed in a 3-year-old male patient. His elder brother died of sepsis which appeared as a consequence of dysgammaglobulinaemia and neutropenia at the age of 9. We could not achieve a parmanent good result with the monthly immunoglobulin substitution and supportive treatment. The candida infection of the gingiva and of the oral mucous membrane expanded to the esophagus resulting in its complete occlusion and temporarily a gastrostomy was needed to feed him. We started with the recombinant human granulocyta colony stimulating factor (rh-G-CSF) treatment at the age of 6. We tried several ways of applying and finally the 10 micrograms/kg/dose given subcutan, for 5-10 days from the nadir of the neutropenic cycle seemed the most effective. The rh-G-CSF treatment resulted in an increase of ANC and the complete resolution of gingivostomatitis. The incidents of infections, the requirement of antibiotics and the duration of hospitalisation were markedly reduced. The consequent improvement in his physical condition made it possible to finally resolve the esophageal stricture surgically. We have not observed any neutropenic cycle since the end of the 14 month rh-G-CSF treatment. Though the medicine was discontinued there has been no recidiva for more than 22 months.     

Successful treatment of diarrheal disease associated with enteroaggregative Escherichia coli in adults infected with human immunodeficiency virus

The presence of enteroaggregative Escherichia coli (EAggEC) in stool has been strongly associated with persistent diarrhea. No treatment trials have been done to demonstrate that clearance of EAggEc results in an improvement of diarrheal symptoms. Twenty-four adults infected with the human immunodeficiency virus (HIV) with diarrhea and EAggEC were randomized to a double-blind placebo-control cross-over treatment trial (ciprofloxacin 500 mg orally twice daily for 7 days vs. placebo). After treatment with ciprofloxacin, the subjects had significantly fewer (50%) stools per day (from 5.0+/-2. 9 to 2.4+/-1.9). Intestinal symptoms decreased by 42% after active treatment. EAggEc were eradicated from stool of all participants after active treatment. These data strengthen the link between the presence of the EAggEc in stool and their role in the pathogenesis of diarrheal disease. It is likely that EAggEc are a treatable cause of diarrheal disease in some persons with HIV and no other apparent enteric pathogen.
