Squamous cell carcinoma complicating chronic suppurative hydradenitis.

A 69-year-old male patient underwent excision of hidradenitis suppurativa (HS) affecting both gluteal areas and the perineum. The perineal specimen contained a 1-cm superficially invasive, well-differentiated keratinizing squamous cell carcinoma. The patient was free of recurrence 1 year after surgery. A 66-year-old male patient was diagnosed with massive perineal HS more than 40 years previously. More than 30 abscesses and suppurative sinus tracts were surgically treated over the years. He eventually died of unresectable pelvic squamous carcinoma. Search of the literature and available bibliography revealed 47 retrospective studies of skin carcinoma arising in HS since 1959, including a total of 64 patients together with the two patients treated by our team. Squamous cell carcinoma is a rare but potentially fatal complication of HS. Surgery is the only known treatment method that provides a real chance for cure for both HS and a carcinoma that complicates it. HS must be treated early with complete excision to avoid chronic progression of the disease that can cause cancerous degeneration. A high index of suspicion, early tissue diagnosis, and immediate referral for radical surgery carry the only hope for cure in those whose HS harbors malignancy.

Large neomucosal space 25 years after mesh repair of ventral hernia.

A 64-year-old, otherwise healthy, male patient presented with a malodorous abdominal wall fistula of recent onset. He gave a history of mesh repair of ventral hernia 25 years ago. Computed tomography scan of the abdomen revealed a 15 cm x 15 cm thick-walled cavity inside the abdomen adjacent to bowel loops and the prosthetic mesh. Resection of the mass included a 25-cm segment of small bowel. Histopathology revealed a thick-walled large cavity lined with mucosa, surrounding a large wrinkled sheet of permanent mesh.

Ogilvie syndrome and herpes zoster: case report and review of the literature.

BACKGROUND: The very unusual association between herpes zoster and Ogilvie syndrome has received scant attention in the published literature. OBJECTIVES: This review discusses the published experience since 1950 and attempts to increase clinical awareness about the co-existence of both conditions. CASE REPORT: An 84-year-old male patient affected by herpes zoster presented with advanced acute colonic pseudo-obstruction and was successfully treated with colonic diversion. DISCUSSION: Twenty published studies (1950-2008) of 28 patients in whom the two conditions co-existed are reviewed. The review included 22 male and 7 female patients (24%) aged 32-87 years (mean, 61 years). Significant co-morbidities were present in 45% of the patients. The majority of patients were observed and treated conservatively (83%). Two patients died (7%), both suffering from respiratory complications and malignancy. CONCLUSION: Recognition of the combined syndrome may help to avoid unnecessary surgery. Laparotomy should be reserved as a last resort for when the obstruction cannot be successfully managed by endoscopy. A diverting colostomy can be used to monitor the blood supply and thus provide early warning for an impending abdominal catastrophe.

Effect of four-day psyllium supplementation on bowel preparation for colonoscopy:A prospective double blind randomized trial [ISRCTN76623768].

BACKGROUND: Patients with new onset constipation or presumed hemorrhoid bleeding frequently require the use of both fiber supplements and diagnostic colonoscopy. We sought to determine whether preliminary fiber supplementation would alter the tolerability or efficacy of a standard bowel preparation for colonoscopy METHODS: A prospective, double blind, randomized trial was designed to compare a short course of a psyllium-based supplement versus placebo prior to a colon lavage. Patients were given an unlabeled canister of powder, and instructed to take 1 tablespoon with 8 oz of water bid for 4 days before colonoscopy. A 4-liter polyethylene based glycol lavage was self-administered over 4 hours on the day prior to colonoscopy. A questionnaire on pre-study bowel habits and side effects was completed. Efficacy of the preparation was visually evaluated on a pre-determined scale. RESULTS: There were no significant differences between the two groups in gender, race, age, pre-study stool frequency or consistency. Tolerability was equivalent but efficacy of the bowel preparation was worse in the psyllium group compared to placebo (P < 0.05). CONCLUSIONS: In non-constipated patients psyllium based fiber supplementation should not be initiated in the few days prior to endoscopy using a polyethylene glycol preparation.

Trace Elements in Head and Neck Cancer Patients: Zinc Status and Immunologic Functions.

In this study we have assessed zinc status and zinc-dependent cell-mediated immune functions (interleukin-2 production by mononuclear cells, natural killer cell lytic activity, and interleukin-1ß production by mononuclear cells) in adult patients with squamous cell carcinoma of the upper aerodigestive tract at diagnosis and before any therapy was instituted. Inasmuch as significant interactions between zinc, copper, and iron exist, we also assayed the plasma copper level, serum iron level, and total iron-binding capacity in our patients. We recruited 30 cancer subjects and 21 control subjects. On the basis of cellular zinc criteria, we diagnosed a mild deficiency of zinc in 53% of cancer subjects. The plasma zinc level was not decreased in our subjects. A univariate analysis was applied by use of one-way analysis of variance comparing study variables among the three study groups (controls and zinc-deficient and zinc-sufficient cancer patients) and Tukey's multiple comparison test, and we showed that interleukin-2 production and natural killer lytic activity were decreased in zinc-deficient cancer patients. Interleukin-1ß production (ELISA assay) was increased in both zinc-deficient and zinc-sufficient groups. Plasma copper level was not different, but the iron utilization was decreased in both groups of cancer subjects. We conclude that zinc deficiency and zinc-dependent immunologic dysfunctions are present in more than half of the patients with head and neck cancer in the Detroit area.
